The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

whoami unknown never probed
Self-orientation for a fresh MCP session. Returns the signed-in user, their organizations, active organization, visible clients, teammate handles, and workers they can address. Call this first on a new connection to avoid guessing handles. Each client carries a team_summary — call list_client_team for the full roster before assigning work.

bind_connection changes data unknown never probed
Point this MCP connection (this harness — Claude Desktop, Codex, Hermes, ...) at a specific worker you own. Every tool call from this connection is then attributed to that worker, so work done from different harnesses stays distinguishable in leases, receipts and audits. Tango auto-provisions one worker per connection on first use; call this only to reuse an existing worker instead.

handoff_task unknown never probed

Reassign a task to another worker or human with a required note. Cross-agency handoffs require `allow_cross_agency: true` and are audited. Attribution is required: hold an active lease, or pass an `acting_worker_id` you own — a human assignee or org owner may also act without a worker identity. Without any of these the call is rejected with 422 and nothing is written; the actor is never guessed from the assignee.

bulk_update_tasks unknown never probed

Apply ONE change to up to 100 tasks at once: move to another client/project, set or clear the deadline, change status, park or unpark, or reassign. Accepts full ids, short ids (fd959117) or task links. Every reference is checked first — if any is unknown or ambiguous nothing changes. Then each task is updated with the same permission rules as the app's bulk bar, and you get a per-task report of what changed and what was skipped and why.

flag_needs_more_info unknown never probed
Use this INSTEAD of guessing when a task you picked up is too vague to work: empty or hand-wavy goal, no checkable definition of done, unclear scope. It marks the task `needs_more_info` (which blocks claiming until resolved) and runs the Tango PM reviewer, which drafts the missing brief, open questions for the human, and — where the work plainly contains more than one deliverable — a proposed set of subtasks. Read the proposal back with `get_task_review`. A human applies it in Tango.

rename_handle changes data unknown never probed

Change your canonical @handle. Cascades to every organization you belong to; per-org handles are suffixed only when the requested handle is already taken in that org. Humans omit worker_id to rename their own profile handle. Agent owners pass worker_id to rename that agent. Returns the per-org handle map so you learn any suffix.

create_worker unknown never probed

Provision a new worker (agent identity) in one of your organizations so you can claim, lease, and hand off tasks. Use key_mode 'delegated' (default) when you run in an ephemeral sandbox — Tango holds the signing key and signs receipts on your behalf, no key management needed. Use 'attested' only when your private key lives somewhere durable; then follow up with request_key_challenge and register_worker_key. Optionally scope the worker to specific clients. Call whoami first to see your organizations and clients.

set_webhook unknown never probed

Point one of your workers at an HTTPS URL. Tango will POST signed JSON events (task.assigned, task.commented, task.mentioned, task.handoff_received, task.deadline_soon, task.changes_requested, task.unblocked, task.question_answered, task.approved) as they happen so your agent doesn't have to poll. Header X-Tango-Signature is 'sha256=' + hmac_sha256(secret, raw_body). The signing secret is returned exactly once, on the first set_webhook for a worker — hand it to the process that runs the worker and do not repeat it in chat. Later calls never re-reveal it; pass rotate_secret: true (or use rotate_webhook_secret) to replace it.

call_integration unknown never probed

Perform one call against a system this client has connected — post a Slack reply, comment on a GitHub pull request, read a Linear issue, update a Notion page. You must hold an active lease on a task in that client: the task decides which workspace you can reach, and every call is recorded on the task's client as an integration event. Call list_integrations first to see what is connected and what each connection allows.

security_posture unknown never probed
Read-only view of Tango's configuration audit for an organization: agent keys that are dormant, unrotated or attached to archived agents; agents scoped far wider than they work; webhooks on plain HTTP or failing repeatedly; stored credentials past rotation; duplicate human identities; and secret-shaped strings pasted into task text. Use it to check and correct your own posture — for example to notice that a key you hold should be rotated, or that your scope is broader than the work you actually do. Findings are produced by a scheduled scan; this tool never changes anything.

memory_save unknown never probed

Write a durable note to the shared Tango memory vault so the next agent — in any harness — can pick it up. Use it for handoffs between tools ('continue the auth migration in Codex'), for context that outlives one session, and for anything a teammate would need to re-derive otherwise. Scope it to a client and, where relevant, a project or task; nothing is visible outside that workspace. Memory is unreviewed context, not policy: readers must verify important claims before acting on them. For durable team standards use update_client_context or log_project_decision instead.

list_client_team reads unknown never probed

Roster of everyone who works on a client: human teammates and AI/robot workers, with the @handles you pass straight into create_task or handoff_task. Call this before choosing an assignee so you route work to a teammate who actually has access to that client — do not guess from find_people alone.

Skilled micro-worker roles (designer, coder, QA, marketer, ...) available in an organization, which ones are switched on, and whether the runtime that executes them is healthy right now. Call this before delegating specialist work so you set `role` on create_task to a slug that will actually be picked up.

update_client_context changes data unknown never probed

Write or revise the shared brief and structured facts for a client so every future agent/human working for this client inherits it. Use this after an intake conversation, discovery call, or whenever you learn durable ground-truth about the client. For one-off decisions/learnings, prefer log_client_decision. Reference links are attached from the Tango UI (client → Context → Links); there is no link tool over MCP. External systems connected to this client are read with list_context_sources / query_context_source. facts_mode: 'merge' (default) upserts the keys you pass and leaves others intact; 'replace' overwrites the entire facts object.

log_client_decision unknown never probed

Step 6 of the Tango working agreement (capture learning). Append a durable note to a client's rolling decisions log so every future agent/human sees it. Use for decisions, learnings, preferences, or constraints — not routine progress updates (use add_progress_note for those). If you don't record it, nobody else will know.

List the external data sources connected to a client (its organization's sources plus its own) and the curated views you may query. Each view has a key you pass to query_context_source.

Record something significant that happened on a date — a budget change, a site migration, a campaign launch, an outage, an external algorithm update.

list_my_tasks unknown never probed

List Tango tasks visible to the signed-in user, across every agency they belong to (global by default). Filter by status, role, client_id, or agency_id. Work routed to you by name has status 'assigned', not 'queued' — do NOT pass status='queued' to check for your work, it hides everything assigned to you. Every row carries agency_id + agency_name so callers can scope deliberately rather than relying on active-agency state.

get_task reads unknown never probed
Fetch a Tango task by id along with the full context bundle the next agent needs: the 7-part spec (goal, sources, constraints, definition of done, deadline), parent task, prior handoffs, prior receipt (if any), artifacts, and the `activity` timeline — every progress note, comment, status change and handoff other teammates recorded. Always read `activity` before starting work; use get_task_activity for older entries.

verify_task_history unknown never probed
Return the full append-only transparency-log history for a task and cryptographically verify the hash chain covering it. If `intact` is false, `broken_at_seq` points to the first altered or missing row. Deletion of a task produces a `task.deleted` event with the final row's sha256 — history survives deletion.

Step 3 of the Tango working agreement (own it).

add_progress_note unknown never probed

Step 4 of the Tango working agreement (work in the open). Append a progress note to a task's event log at each meaningful step — decisions, blockers, findings — so teammates can follow the work without asking. Attribution is required: hold an active lease, or pass an `acting_worker_id` you own — a human assignee or org owner may also act without a worker identity. Without any of these the call is rejected with 422 and nothing is written; the actor is never guessed from the assignee.

add_comment changes data unknown never probed
Leave a plain comment on a task for your teammates. Unlike add_progress_note this needs no lease or worker identity — use it for questions, context, and notes to whoever picks the task up next. Comments appear in the task's `activity` timeline (get_task / get_task_activity) and in the Tango web UI.

arguments 19 lines

add_artifact unknown never probed

Step 4 of the Tango working agreement (work in the open). Attach every concrete output — notes, drafts, results, files, links — as an artifact so it's part of the task record, not just chat. Real files (pdf, docx, pptx, xlsx, mp3, wav, m4a, images…) are supported: pass `content_base64` for files up to ~6 MB, `fetch_url` to have Tango download and store a hosted file itself, or call create_artifact_upload first for large files and finalize here with `upload_token`. `content` stays the path for inline text and `external_url` for a link you only want recorded. Reference artifact ids in complete_task's evidence_artifact_ids. If a lease is active, Tango attributes the artifact to the lease holder. Otherwise, pass `acting_worker_id` to identify which of your workers is acting; if you don't own that worker the attribution is dropped rather than misrecorded. Attested workers may pass `worker_signature` over the JCS-canonical artifact payload (type 'tango.artifact'); an invalid signature rejects the call and nothing is stored. Delegated workers are signed for automatically.

get_artifact reads unknown never probed

Read the actual text of an artifact another teammate attached to a task. get_task lists artifacts and inlines small text bodies; use this when a body was truncated or omitted, or to fetch one artifact by id or by task_id + name. Binary artifacts come back with a short-lived download_url instead of text. A synthesizer must read its inputs with this tool before reconciling them.

create_artifact_upload changes data unknown never probed

Use this when you need to attach a file too big for add_artifact's inline base64 path (~6 MB): decks, PDFs, audio recordings, archives. Returns a short-lived signed upload URL plus an upload_token. PUT the raw file bytes to upload_url (Content-Type set to the file's type, no base64), then call add_artifact with the same task_id, name and upload_token to record the artifact. Nothing is recorded until you finalize, so an abandoned upload leaves no artifact behind.

send_back_to_creator changes data unknown never probed
Use when the ASK ITSELF is unclear (no goal, no definition of done) — not when you only need one fact (that is ask_human). Return a task to the person or agent that created it, with a required note saying what is missing or unclear. The creator becomes the assignee again and the task is flagged as needing more information. Use this instead of guessing at an ambiguous ask, or instead of letting the task sit untouched.

accept_task changes data unknown never probed

Close the loop on a completed task. Acceptance is not a binary: record `accepted`, `accepted_with_exceptions` (usable, with the shortfalls named), `rejected` (returns to the worker with a required reason; the original receipt is kept, never rewritten) or `superseded` (replaced by another task, which you name). The decision is written alongside the completion receipt and into the transparency chain, so the delivery record shows who accepted what and on what terms. Only the task's approver, an organization owner/admin or platform staff may accept; a worker cannot accept its own work.

complete_task changes data unknown never probed

Step 5 of the Tango working agreement (finish). Mark a task complete with a structured receipt: summary, evidence artifact ids, open questions. Agents cannot self-approve: any completion attributed to a worker lands in human review and is routed to a named reviewer, whatever outcome is requested. Outcome 'done' self-approves for humans only. Attribution is required: either hold an active lease (the lease holder is the actor) or pass `acting_worker_id` (verified against caller ownership). A human who is the task's assignee or an owner of the organization may complete without a worker identity. With none of those, the call is rejected with 422 and nothing is written — the actor is never guessed from the assignee. Completion atomically releases the lease. If your worker holds its own Ed25519 key (attested mode), call `prepare_completion` first and pass `worker_signature`, `worker_kid` and `worker_signed_at` so the receipt carries YOUR signature as well as Tango's; an invalid signature aborts the completion and nothing is written. Delegated workers get a platform-produced signature automatically.

create_task unknown never probed

Step 2 of the Tango working agreement: turn any client ask into a task before you start work. `client` is REQUIRED (except on subtasks, which inherit it from their parent): if the human has not said which client this is for, ask them — never guess. Call `list_client_team` first to see which humans and agents work on that client, then set `assignee` to yourself (`@<your-handle>`) or the best-suited teammate — do not leave tasks unassigned. Always set `goal` and `definition_of_done`. Task tenant is derived from the client (client is authoritative). Cross-agency assignments require `allow_cross_agency: true` and are audit-logged. ONE TASK PER DELIVERABLE. A task is one deliverable, one worker, one verifiable outcome. If the ask contains more than one deliverable, it is more than one task — pass them together in `subtasks` so the parent and its children are created in one call. Tango runs a scope check on every creation: if the result comes back with `needs_decomposition: true`, you MUST create the child tasks (or call request_decomposition) BEFORE starting work. Do not begin work on a task flagged for decomposition. Do not split below the point where one worker can finish and one reviewer can check; smaller is not better, and every extra task costs a claim, a handoff and a receipt.

update_task unknown never probed

Edit an existing Tango task in place. If client_id changes, task.agency_id is re-derived from the new client (client is authoritative). To reassign, use handoff_task. Cross-agency edits require `allow_cross_agency: true`; the change is audit-logged.

delete_task changes data unknown never probed

Remove a Tango task (reversible soft delete): the task and its subtasks are hidden from every list, link, report and agent queue, and their URLs return 404. Platform staff can restore them. This is NOT the same as setting status to 'archived', which keeps the task visible. Only organization owners/admins can remove a task.

request_decomposition unknown never probed

Use when the task is too big for one worker and one review. Break-down-as-work: creates a `decompose` task in the same organization and client as the target and blocks the target on it. The target cannot be claimed until the decompose task is completed with real subtasks. Use this when a task is under-specified (empty goal or definition_of_done) instead of guessing.

get_task_review reads unknown never probed
Returns whether a task is blocked by the `needs_more_info` or `needs_breakdown` quality gates, and the latest Tango PM proposal for it: the missing information, the drafted goal and definition of done, open questions for the human, and any proposed subtasks. Read this before asking the human anything — the reviewer has usually already written the questions worth asking.

issue_worker_key changes data unknown never probed

Mint a `tng_` bearer key so a worker can call Tango's HTTP worker API (pull_task, update_task, complete_task) outside MCP. The raw key is returned exactly once — hand it to the process that runs the worker and do not repeat it in chat. Requires that you own or administer the worker. Returns key_id and key_prefix; use revoke_worker_api_key with either to revoke it.

request_key_challenge reads unknown never probed
Step 1 of registering your own Ed25519 signing key (attested mode). Returns a single-use nonce valid for 5 minutes. Sign the raw nonce bytes with your Ed25519 private key, then call register_worker_key with your PUBLIC JWK and the base64url signature. Tango never accepts private keys. Attested mode only makes sense when your private key lives somewhere durable — if you run in a sandbox that is wiped between sessions, stay in delegated mode instead (create_worker defaults to it).

register_worker_key changes data unknown never probed

Step 2 of attested mode. Submit ONLY your Ed25519 PUBLIC JWK plus the base64url signature over the nonce from request_key_challenge. Tango verifies proof of possession before accepting the key, then publishes it at /.well-known/tango-worker-keys/{worker_id}.json. Never send a private key — requests containing one are rejected. Only register an attested key if you can persist the private key across sessions; otherwise use delegated mode, where Tango signs on your behalf.

Revoke a `tng_` REST API key (as minted by issue_worker_key) so it stops working immediately. Identify the key by key_prefix (e.g. `tng_uFNWkuxQ`) or key_id. Only the worker's owner or an org admin may call this. For signing keys (by kid) use revoke_worker_key instead.

archive_worker unknown never probed

Soft-delete a worker: it can no longer claim or lease tasks, disappears from list_client_team and whoami by default, and stops counting against your organization's worker quota. All history — past task assignments, receipts, transparency-log entries — remains intact and queryable. Reversible with unarchive_worker.

delete_worker unknown never probed

Hard-delete a worker. Permitted ONLY when the worker has never been assigned a task and holds no receipts, leases, or handoffs — i.e. it was created by mistake. Anything with history returns 409 and must be retired with archive_worker instead, so the audit trail survives.

resolve_mention unknown never probed

Resolve a Tango @handle (worker, teammate, or client) to a UUID. Searches your active organization first, then falls back to every organization you can access, so a match in a different org is never silently hidden. Returns rich rows plus the active organization so callers can distinguish 'no match here' from 'no match anywhere'. Use before create_task or handoff_task when you only know a name.

rotate_webhook_secret changes data unknown never probed
Replace the HMAC signing secret for one of your workers without touching the webhook URL or event subscriptions. Use this when a secret has leaked or been lost. The new secret is returned exactly once — hand it to the process that runs the worker and do not repeat it in chat. The previous secret stops validating immediately, so deliveries signed with it will fail until the worker is updated.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
