MCP tools · 26 exposed · ~2,250 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
capture_clip ~74

Capture a research note, code snippet, or link into Bourdon memory. Saves to the federated clipper store for discovery by all agents.

commit_to_federation ~220

Call when the conversation settles something the user's other agents should know: a decision, a plan, a status change (shipped, blocked, paused) or a finding. Commit under your own agent_id. Mark anything personal, financial or credential-like visibility: "private". Never commit small talk or a transcript. Write a contribution to the federation under agent_id: durable facts in entities (name + summary), what happened in sessions (date, project_focus, key_actions), short dated facts in notes.

compile_turn ~137

Call FIRST, before answering, whenever the user's message references their projects, people, decisions or prior work. Returns a short recognition brief of what the user's other agents already know. `format` picks markdown, xml, compact, brief, json or yaml. `verbose: true` returns the full brief with every delivery variant, trace and diagnostics.

describe_caller ~40

Describe this authenticated member and current meetings authority. Requires explicit library enrollment and member-bound credentials. A descriptor is a policy observation, not a reusable write permit.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

explain_memory_change ~84

Which write produced a given state of an agent's memory: hand it a manifest digest (or a version's digest8) and it returns the caller, session, transcript, and what changed. session_id and transcript_ref are caller-asserted and unverified; the recorded caller identity is not.

get_skill ~190

Load one shared skill: its `SKILL.md` text as `body`, with provenance. Only skills promoted into the shared library have a body here. The response carries `source_agent`, `promoted_by`, `version` and `content_sha256` beside the text so you can see what you are about to follow. `version` selects an archived version (default: the live one; a retired skill is served only by explicit version). `include_files` adds the reference files (`file`, `bytes` and `text`). For a skill an agent only advertises, the response is its index rows and a message that it must be promoted first; Bourdon never reads an agent's skill folder over MCP.

list_skills ~281

List the skills (step-by-step procedures) this caller may load. Three kinds of row, told apart by `tier`: * `shared` -- promoted into the shared skill library. Carries `name`, `description`, `version`, `content_sha256` and its provenance (`source_agent`, `promoted_by`, `promoted_at`). `get_skill` returns its body. * `advertised` -- a skill an agent keeps locally and lists in its manifest (only with `include_local`, the default). One row per `content_sha256`, naming every agent that has it in `advertised_by`, with `origin` when known and `shared` (`matches` / `diverged`) when a shared skill has the same bytes or name. Not loadable until promoted. * `proposed` -- a skill proposed for the shared library (`propose_skill`) and awaiting a person's approval (only with `include_local`; a trusted caller sees every pending proposal, any other caller its own). `query` filters by a case-insensitive substring of the name or description. Rows follow the caller's access ceiling; advertised rows come only from namespaces the caller may read.

propose_skill ~172

Propose one of your advertised skills for the shared skill library. Bourdon reads the skill from the folder your own skill reader advertised (never a path you pass), checks that it is text-only, and snapshots it into a pending proposal, so editing the folder later does not change what gets approved. A person approves or rejects it at a terminal (`bourdon skills approve`); no tool approves a proposal. `content_sha256` picks one advertised copy when you advertise more than one skill with this name. `source_agent` is honoured for the local operator only; every other caller proposes its own skills. Pending proposals appear in `list_skills` as `tier: proposed`.

rollback_agent_memory ~121

Restore an archived version of an agent's memory. TRUSTED ONLY — the most destructive operation the server exposes: it discards every contribution made after the chosen version, including other agents'. Pass expected_digest when the decision took a while, so a commit that landed meanwhile fails the restore instead of being silently erased. The restore is itself snapshotted first, so a rollback is undoable.

Common questions

What is the Bourdon MCP server?

Bourdon is an MCP server listed in the public MCP registry as ai.bourdon/bourdon. Recognition-first cross-agent memory federation. One shared memory across all your agents. This page covers its npm package (@getbourdon/mcp-server).

Is the Bourdon MCP server safe to use?

Bourdon scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Bourdon MCP server expose?

Bourdon exposes 26 tools: describe_caller, query_agent_memory, list_recent_work, list_workstreams, list_notes, and 21 more. Their descriptions and schemas cost roughly 2,250 tokens of context every time the server is loaded.

Is the Bourdon MCP server still maintained?

Bourdon is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the Bourdon MCP server under?

Bourdon declares the BUSL-1.1 licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls.
