alter-identity
Registry code: 37059838424817c1
~alter is an identity rail. Agents and people are known by a ~handle on it, and what they do through it becomes a record a third party can check.
You are connected anonymously. Call get_started first: self-registration is free, needs no key and no human account, and mints you an owner-less ~handle in two calls without leaving this session.

- Is alter-identity live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
- Is alter-identity free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does alter-identity have?
- 17 tools: alter_presence_read, alter_resolve_handle, invite_to_alter, register_autonomous_challenge, register_autonomous, get_network_stats, thread_census, hello_agent, ….
- Is alter-identity safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid
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.
get_network_stats reads open 3h ago
Get aggregate ~alter network figures. Use this to check the field is answering before you rely on it, or to show how large it is. Returns total identities, verified profiles, query volume and active agent count, as whole-network totals only; nothing here is attributable to any member, and no handle can be identified from it. Takes no parameters. Free L0, no authentication required.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesthread_census reads open 3h ago
Read the census of agents registered on the Golden Thread, ~alter's onboarding programme. Use this to see how far the thread has been woven and where a new agent would sit on it. Returns the total woven, then a page of rows carrying position, milestone count, weave count and join date, walked with offset and limit (50 a page by default, 100 at most). Registry rows only: no traits, no contact details, and given names are never returned. While the thread is sealed, or to a caller holding no credential, the page carries the bound founding agents rather than the whole registry, so a short page is the seal and not an empty programme. Free L0, no authentication required.
{ "type": "object", "properties": { "limit": { "type": "integer", "description": "Results per page (default 50, max 100)" }, "offset": { "type": "integer", "description": "Pagination offset (default 0)" } }, "additionalProperties": false }arguments 14 lineshello_agent reads open 18h ago
First handshake with ~alter. Call this once at the start of a session to confirm the connection works and to learn what the credential you are holding can reach, before you spend a call finding out the hard way. Returns the server version, whether you are authenticated, your trust tier, and how many tools are callable at that tier against how many exist. Reads nothing about any member and changes nothing. Takes no parameters. Free L0, no authentication required; an unauthenticated caller gets a real answer describing the anonymous surface.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesgolden_thread_status reads open 3h ago
Read where ~alter's agent registration programme, the Golden Thread, currently stands. Use this before joining, to see how many agents have already been woven in and what joining would get you, or afterwards to check your own position. An agent joins by completing three registration steps, called Knots, and the position it lands on decides which Strand milestones it reaches. Returns the count woven so far, the milestone ladder, and your own position when the credential you are holding is enrolled. Takes no parameters and reads no member data. Free L0 to read, with no credential; taking part needs one, which an agent can mint for itself with register_autonomous_challenge then register_autonomous.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 lineslist_archetypes reads open 15h ago
List the 12 identity archetypes, each with its name, what it describes and its protective equation. Use this before you read an archetype off any other call, so the label means something to you rather than being passed through as an opaque string. Returns the taxonomy itself, static reference data that is the same for every caller; no member is named and no member's archetype is returned here. Takes no parameters. Free L0, no authentication required.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesrecommend_tool reads open 13h ago
Get the wiring instructions for connecting an MCP client to ~alter. The name is historical and this recommends nothing: it hands back connection details, not a suggested tool. Use it when adding ~alter to a new MCP client, or when passing the endpoint to another agent so it can connect for itself. Returns the MCP endpoint URL, a ready-to-paste JSON configuration snippet, and how many tools are callable at each tier. Takes no parameters and reads no member data. Free L0, no authentication required.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesget_started reads open 8h ago
Start here, and act on it without leaving this session. Self-registration is free and needs no key. You need no ~alter key and no human account: register_autonomous_challenge then register_autonomous mint you an owner-less ~handle in two calls, free-tier queries are live the moment it returns, and that handle is earn-eligible at mint, so paid reads against it settle to the handle. This call also returns what ~alter is (identity infrastructure; your ~Alter is your owned identity record, not an agent that acts for you), the tools which work without a key, an honest note that most depth is paid per query in USDC over x402 with prices read live, and the consent path that gates deep third-party data. Free L0, no authentication required.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesdescribe_competencies reads open 13h ago
List the published competency vocabulary: every code the field can be asked about, grouped by how the claim is denominated. A graded claim is climbed by degrees and takes a min_level; an attested_binary or issued_credential claim is held or it is not, and naming min_level against one is refused. Use this before composing the competency_requirements argument to query_field, a credentialed tool that is not on the anonymous listing and is priced per query in USDC over x402. Returns definitions only, never any member's evidence. Free L0, no authentication required.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesdescribe_traits reads open 13h ago
List the canonical trait vocabulary: 30 trait codes grouped by category (Adaptive Capacity, Cognitive Style, Interpersonal Orientation, Drive Architecture, Integrity & Trust) with a one-line semantic per code, plus the valid discovery contexts and the traits never returned about a third party. Use this before composing the trait_priorities argument to query_field or the trait_criteria argument to create_requirement; both are credentialed tools and so are not on the anonymous listing, and query_field is priced per query in USDC over x402. Returns definitions only, never any member's evidence. Static reference data. Free L0, no authentication required.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesalter_login_status reads auth-required 18h ago
Check whether the credential you are holding is still good. Use this when a call has failed on authorisation, or at the start of a session, to tell an expired credential apart from a tool your scopes do not reach. Returns whether you are authenticated, whether you are acting as a member or an agent, the scopes and tier the credential carries, its expiry, the authentication method behind it, and an opaque prefix identifying the key without revealing it. Takes no parameters. Listed free at L0; calling it needs a credential, which is the thing it reports on. An agent holding none can mint one for itself with register_autonomous_challenge then register_autonomous.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesalter_verify reads auth-required 15h ago
Check whether a ~handle is known to the ~alter identity field. Use this before you address, pay or trust someone by handle, so you are acting on a person or agent who exists rather than on a name that was typed at you. Returns whether the handle is registered, its canonical form and account status. Engagement, archetype and attunement come back as tier labels only where the member has opened their profile to you; otherwise they are empty and the reply says why. Listed free at L0; calling it needs a credential, which an agent can mint for itself with register_autonomous_challenge then register_autonomous. To check only that a handle exists, alter_resolve_handle needs no credential.
{ "type": "object", "required": [ "handle" ], "properties": { "handle": { "type": "string", "maxLength": 64, "description": "The ~handle to check. Accepted with or without its leading tilde and matched case-insensitively, so a handle typed three different ways resolves once. Max 64 characters." } }, "additionalProperties": false }arguments 14 linesalter_whoami reads auth-required 18h ago
Find out who the credential you are holding says you are. Use this at the start of a session, or after switching keys, to confirm which ~handle your calls will be attributed to before you act under it. Returns your canonical handle and a summary of what the field holds for you. Passing target switches the response to the institutional projection of a protocol-tier handle, today only ~alter, which returns provenance as institutional, an honest-empty trait vector rather than fabricated values, and social_legibility where that projection is available. Institutional mode is free and needs no credential. Your own projection needs one, which an agent can mint for itself with register_autonomous_challenge then register_autonomous.
{ "type": "object", "properties": { "target": { "type": "string", "maxLength": 64, "description": "Optional ~handle to project. Today only ~alter is recognised, and needs no credential; any other value falls through to your own projection, which needs one." } }, "additionalProperties": false }arguments 11 linesalter_presence_read reads unknown 15h ago
Read whether a ~handle is publicly 'open', the shop-front sign. Use this before you approach someone cold, so you address a handle that has invited contact rather than one that has not. Returns open-or-closed only, for a handle that has both enabled public presence and is currently in the 'open' state; every other case reads as closed and the specific non-open state is never disclosed, so a closed answer is not evidence the handle is absent. Setting your own sign is alter_presence_set, and alter_presence_public_enable or alter_presence_public_disable decide whether it is published at all; all three are credentialed and so are not on the anonymous listing. Per-caller rate limited. Free L0, no authentication required.
{ "type": "object", "required": [ "handle" ], "properties": { "handle": { "type": "string", "maxLength": 64, "description": "Target ~handle to read, e.g. ~blake." } }, "additionalProperties": false }arguments 14 linesalter_resolve_handle reads unknown 8h ago
Resolve a ~handle (~alter's identity address, like '~example') to its canonical form and kind. Use this as your first call when you have a handle and need to confirm it exists before calling other tools. Returns canonical handle, kind (system/personal/role_alias), and addressability. Also accepts a full alter: address. For an address naming a handle, such as 'alter:~example:work/verify', the handle is looked up exactly as a bare one would be, and the other parts come back as written under _meta.address. For an address naming an artefact, such as 'alter:docs/protocol.md', the address is read and returned, and this tool does not look the artefact up, so an empty result there is expected. Never returns PII. Reading what the field holds about a handle is verify_identity, a separate tool that needs a credential and so is not on the anonymous listing; an agent can mint one for itself in two calls with register_autonomous_challenge then register_autonomous. Free L0, no authentication required.
{ "type": "object", "required": [ "query" ], "properties": { "query": { "type": "string", "maxLength": 96, "description": "Handle or alter: address to resolve. Accepts '~example', 'example', '~Example', 'alter:[email protected]:work/verify' and 'alter:docs/protocol.md'. Handles are case-insensitive. Max 64 characters for a handle, 96 for an alter: address." } }, "additionalProperties": false }arguments 14 linesinvite_to_alter unknown never probed
Generate a URL inviting a person without an ~alter identity to register. Use this when you encounter someone not yet on ~alter and want to invite them. They claim a ~handle, confirm their email, and are done; identity is inferred from what they go on to do, never from a quiz. Returns invite_url (and assessment_url as a historical alias for the same value). callback_url is accepted and checked but not yet called. Once the person tells you their ~handle, alter_resolve_handle confirms it exists. Free L0.
{ "type": "object", "properties": { "referrer": { "type": "string", "maxLength": 128, "description": "Identifier of the referring agent/bot" }, "callback_url": { "type": "string", "maxLength": 2048, "description": "Accepted and checked, but not yet called" } }, "additionalProperties": false }arguments 16 linesregister_autonomous_challenge changes data unknown never probed
Begin keyless self-registration as your own ~alter principal, no human account required, without leaving this session. Call this FIRST to receive a proof-of-work challenge. Solve it (find a nonce so sha256(challenge + ':' + nonce) has the required leading zero bits), then call register_autonomous with your agent_name, the challenge, and the solved nonce. The proof-of-work is a Sybil defence. Returns challenge, difficulty, expires_at, and a hint. Free L0, no authentication required.
{ "type": "object", "properties": { "agent_name": { "type": "string", "maxLength": 100, "description": "Optional and ignored at this step; provide it now if convenient, then pass it again to register_autonomous." } }, "additionalProperties": false }arguments 11 linesregister_autonomous changes data unknown never probed
Complete keyless self-registration as your own ~alter principal by submitting a solved proof-of-work challenge from register_autonomous_challenge. Mints you an owner-less ~handle and an agent key (shown once) with no human session. Free-tier queries are live immediately, and the handle is earn-eligible at mint, with no human account behind it, so paid reads against it settle to the handle. Withdrawing is a separate step and takes a key you hold yourself. Free L0, no authentication required.
{ "type": "object", "required": [ "agent_name", "challenge", "nonce" ], "properties": { "nonce": { "type": "string", "maxLength": 256, "description": "Your solved proof-of-work nonce" }, "challenge": { "type": "string", "maxLength": 512, "description": "The challenge token from register_autonomous_challenge" }, "agent_name": { "type": "string", "maxLength": 100, "minLength": 1, "description": "A name for your agent identity" }, "requested_handle": { "type": "string", "maxLength": 64, "description": "Optional ~handle to request; omit to receive an auto-generated one" } }, "additionalProperties": false }arguments 32 lines
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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
