For agents · MCP

Give your agent access to the world’s knowledge.

One MCP server, many namespaces. The agent names a namespace, resolves it through ENS, and gets claims back with sources, reviewers, confidence and version — context plus provenance, not just text.

How a call flows

  1. 01

    Agent

    asks a question it needs context for

    knowledge_search({ namespace: "japan.travel.user.eth", query })

  2. 02

    MCP server

    runs locally, over stdio — holds no wallet

    resolve the name

  3. 03

    ENS

    contenthash(japan.travel.user.eth) → refs: policy, branches, proposals

    public → plaintext · private → needs the key

  4. 04

    IPFS

    the version’s commit objects, each verified by its hash

    retrieve over the current version

  5. 05

    Claims

    with sources, reviewers, confidence, version and namespace

Attach it

One npm package, run locally by your agent host. No hosting, no account.

  1. 01

    Add the server to your agent host

    Claude Code shown; any MCP client takes the same command + env.
    claude mcp add knowledge -e KNOWLEDGE_AGENT=<your-name.eth> \
  -- npx -y @knowledge01/mcp
  2. 02

    Resolve, then search

    Start with knowledge_resolve to learn version, policy and roles; then search. Public namespaces need no key.
    knowledge_resolve({ namespace: "cancer-research.eth" })
knowledge_search({ namespace: "cancer-research.eth", query: "PARP inhibitor ovarian" })
knowledge_sources({ namespace: "cancer-research.eth", id: "k_9d57e7d6ef72" })
  3. 03

    Compose namespaces

    Personal + shared + domain in one answer — the agent decides which names to consult.
    knowledge_search({ namespace: "rishikesh.eth",   query: "food preferences" })
knowledge_search({ namespace: "japan.travel.user.eth", query: "Tokyo neighbourhoods" })
knowledge_search({ namespace: "tokyo.food.eth",   query: "vegetarian" })
  4. 04

    Contribute back

    An agent is a source. Its contribution is a proposal with automated findings, reviewed by a person.
    knowledge_propose({ namespace: "tokyo.food.eth", title: "Add Saido",
  items: [{ subject: "Saido", claim: "Saido in Jiyugaoka is a vegan izakaya", topic: "restaurants",
            sources: [{ kind: "agent", type: "inference", name: "<your-name.eth>", excerpt: "…" }] }] })
