READ FIRST: the tools you can see are NOT all of emem. They are a small loop, chosen to keep your context small.

Call emem_tools to see the rest, search it, or get one tool's schema and a working example.

_ is it live, free and safe measured by this hub
Is emem live?
Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.
Is emem free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does emem have?
18 tools: Mint or get a canonical object identity, Resolve place to cell64 + band inventory, Compose a memory_token citation handle, Server-side ed25519 receipt verifier, Scan for multi-attester disagreement, What tools exist here, and when to reach for each, Ask a free-text question about a place, Find signed facts for a place, as citable sources, ….
Is emem 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.

_ usage and payments 30 days

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

_ what it can do 18 tools
18 never probed 0 of 18 classified

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.

  • emem_entity changes data unknown never probed

    Give a real-world object (a bridge, a farm plot, a river, a named place) one shared identity. Every agent resolves this identity the same way.

    readL0

  • emem_locate reads unknown never probed

    Get the canonical address (cell64) of a real-world place. Every agent resolves a place to the same cell64, so two models refer to the same ground.

    readL0

  • emem_memory_token changes data unknown never probed

    Make a citation handle, `emem:fact:<cell64>:<fact_cid>` (or `:<state_cid>`). Any agent or LLM resolves it to the same signed object, byte for byte.

    readL0

  • emem_verify_receipt reads unknown never probed

    Verify a signed receipt on the server. The tool builds the canonical preimage again, under the rule that the receipt's `preimage_version` names. It checks the ed25519 signature with the embedded key.

    verifyL1

  • emem_memory_contradictions reads unknown never probed

    Find where the corpus DISAGREES with itself (algebra: competing evidence). Two or more independent sources can sign different values for the same place, band and time.

    readL0

  • emem_tools reads unknown never probed

    The map of emem's tools, and the one tool that finds all the others. It gives the working loop in order (name, ground, cite, resolve, verify, check for drift).

    introspectL0

  • emem_ask reads unknown never probed

    Answer a free-text question about a real-world location in one call. Signed satellite, elevation, water and built-up receipts support the answer.

    readL0

  • search reads unknown never probed

    Search emem's signed corpus and get results as citations. Each entry is one signed fact.

    readL0

  • fetch reads unknown never probed

    Dereference an id from `search`. You get the reading in one line, then the signed body, the URL that serves those bytes, and metadata: cell, band, signing time and key.

    readL0

  • emem_entity_link changes data unknown never probed

    Record a signed, ATTRIBUTED claim that a label or an external id (GERS, OSM, Wikidata) names an existing object. With `stance: "disputes"`, record that it does not.

    writeL0

  • emem_find_similar reads unknown never probed

    Find the k nearest cells in the corpus by cell embedding or by an inline vector.

    readL0

  • emem_recall reads unknown never probed

    Read the signed facts at a canonical address (cell64). When a band has no fact yet but has a registered materializer, the responder fetches it.

    readL0

  • emem_memory_token_resolve reads unknown never probed

    Read a `emem:fact:<cell64>:<fact_cid>` citation handle and return the reading that it cites. `value`, `unit`, `band` and `kind` are at the TOP level of the answer, beside the full signed `fact` body.

    readL0

  • emem_guard_verdict reads unknown never probed

    Run the emem-guard policy checks on text before you send it. The checks use this responder's corpus.

    verifyL1

  • emem_echo_verify reads unknown never probed

    Grade a value that you will emit against the signed fact that your citation cites. The tool returns `matches`.

    readL0

  • emem_memory_bundle changes data unknown never probed

    Combine N (cell, band, tslot?) triples into ONE signed envelope. Each triple goes through the standard recall path, which materializes on a miss.

    readL0

  • emem_entity_resolve reads unknown never probed

    Find the objects that agents connected to a phrase. The tool ranks them by INDEPENDENT corroboration, never by arrival order.

    readL0

  • emem_intent unknown never probed

    State what you want in one typed object and get the answer. You do not choose a primitive. `type` selects the intent AND the other fields that the tool reads. Send only the fields in its row.

    planL0

_ try it over a2a 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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id ac3684b5628369bd.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ac3684b5628369bd/claim. Over MCP: the claim_endpoint tool.

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.

_ 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
0

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.
