# Attach Clawboo's MCP to an external agent

> A worked walkthrough: pick a server and transport, fetch the attach snippet, wire it into Claude Code, Codex, or a custom MCP client, and bind scope safely.

Use this guide when you want an agent that Clawboo does **not** run, a standalone Claude Code session, a Codex CLI, or your own [MCP](/appendices/glossary) client, to join a Clawboo team by attaching one of the four hosted MCP servers (`tasks`, `memory`, `tools`, `teamchat`). Once attached, the external agent reads and claims [board](/concepts/the-board) tasks, searches [shared memory](/concepts/memory), calls brokered tools, and posts in a [team room](/concepts/peer-chat), over the same SQLite store every Clawboo runtime shares.

This composes three references; read them when you need the full shape:

* [Operating: attaching MCP servers](/operating/mcp-servers), the step-by-step operating procedure.
* [MCP tools reference](/reference/mcp-tools), every tool and its zod input schema.
* [Tools & MCP API](/reference/rest-api/tools-and-mcp), the `/api/mcp/*` and `/api/tools*` REST shapes.

<Note>
  Clawboo's own runtimes get a *scoped* attach config injected automatically at run time; the executor builds it from the run's `memoryScope` and passes it through `buildAttachConfig`. An external agent is unscoped by default; this guide shows how to bind it the same way the server binds its own runs.
</Note>

## Prerequisites

<Note>
  Node 22+ (the stdio bins are `node` scripts). For Streamable HTTP, a running Clawboo server (`clawboo`, see [Installation](/getting-started/installation)).
</Note>

* A running Clawboo, or a clean Clawboo install (the four stdio bins ship in the CLI package).
* An external agent that already speaks MCP: `initialize` → `tools/list` → `tools/call`. Anything MCP-capable can attach; it does not have to be a Clawboo runtime.
* The team id (and, for scoping, the agent id) you want the external agent to act as. Read them from [`GET /api/teams`](/reference/rest-api/teams) and [`GET /api/agents`](/reference/rest-api/agents).

## Decide: which server, which transport

You attach one server per concern. The four are independent; attach only what the agent needs.

| Server     | What the agent does with it                    | stdio bin              | HTTP path           |
| ---------- | ---------------------------------------------- | ---------------------- | ------------------- |
| `tasks`    | Read / claim / update board tasks              | `clawboo-mcp-tasks`    | `/api/mcp/tasks`    |
| `memory`   | Search and save shared team facts              | `clawboo-mcp-memory`   | `/api/mcp/memory`   |
| `tools`    | Call brokered tools (gated, approved, audited) | `clawboo-mcp-tools`    | `/api/mcp/tools`    |
| `teamchat` | Post / read in the team room as a named peer   | `clawboo-mcp-teamchat` | `/api/mcp/teamchat` |

Then pick one of two transports for the same four servers:

|                          | **stdio**                                                                   | **Streamable HTTP**                                                      |
| ------------------------ | --------------------------------------------------------------------------- | ------------------------------------------------------------------------ |
| How it runs              | The agent spawns a bin as a child process, talks JSON-RPC over stdin/stdout | The agent connects to the running server's `/api/mcp/<server>` over HTTP |
| Who owns the process     | The consuming agent (spawns + kills the bin)                                | Clawboo (long-running, in-process)                                       |
| DB path                  | Bin defaults to `~/.openclaw/clawboo/clawboo.db`, **set `CLAWBOO_DB_PATH`** | Server's `~/.clawboo/clawboo.db` (always correct)                        |
| Scope / identity binding | Pass identity in tool args (unbound)                                        | Bind via attach-URL query params (recommended)                           |
| Best for                 | Same-machine agent owning its own lifecycle                                 | A separate process or container talking to a long-running Clawboo        |

Both transports read and write the **same SQLite database**, the shared-services bus. A stdio bin spawned by an external agent and the in-process HTTP server operate on one board, one memory store, one tool-call audit.

## Steps

### 1. Get the attach snippet from `GET /api/mcp/config`

Do not hand-write the config. Ask Clawboo to emit it for your runtime, server, and transport:

```bash theme={"theme":{"light":"github-dark","dark":"github-dark"}}
curl 'http://127.0.0.1:18790/api/mcp/config?runtime=claude-code&server=tasks&transport=http'
```

```json theme={"theme":{"light":"github-dark","dark":"github-dark"}}
{
  "ok": true,
  "config": {
    "id": "clawboo-tasks",
    "transport": "http",
    "snippet": "claude mcp add --transport http clawboo-tasks http://127.0.0.1:18790/api/mcp/tasks",
    "structured": {
      "clawboo-tasks": { "type": "http", "url": "http://127.0.0.1:18790/api/mcp/tasks" }
    }
  }
}
```

`snippet` is the copy-paste line; `structured` is the same attachment as an object (for programmatic config such as Claude Code's inline `mcpServers`). The query params:

| Param       | Default       | Values                                                                                                    |
| ----------- | ------------- | --------------------------------------------------------------------------------------------------------- |
| `server`    | `tasks`       | `tasks`, `memory`, `tools`, `teamchat`; an unknown value returns `400 { "error": "unknown server: <x>" }` |
| `runtime`   | `claude-code` | `claude-code`, `codex`, `openclaw`, the three the snippet builder knows how to format                     |
| `transport` | `http`        | `http`, `stdio`                                                                                           |

<Info>
  For `transport=http`, the base URL in the snippet is the server's **own bound port** (`loopbackMcpBaseUrl` reads `app.locals.apiPort`), never the request's `Host` header. A forged `Host` cannot redirect an agent's MCP traffic to another server. For `transport=stdio`, the snippet uses the path under `CLAWBOO_MCP_BIN_DIR` when the server was started with it (the CLI sets it for the bundled bins); otherwise it emits a `<path-to>/dist/bin/<server>.js` placeholder.
</Info>

If your agent is not one of `claude-code` / `codex` / `openclaw`, the snippet builder cannot format its config; but the *structure* is the same. Use the HTTP URL (`<base>/api/mcp/<server>`) or the `node <bin>` invocation directly; only the per-runtime wrapper differs.

### 2a. Wire it in: over HTTP (Claude Code)

Point the agent's MCP client at `<clawboo-base>/api/mcp/<server>`. For Claude Code, the snippet is a ready command:

```bash theme={"theme":{"light":"github-dark","dark":"github-dark"}}
claude mcp add --transport http clawboo-tasks http://127.0.0.1:18790/api/mcp/tasks
```

The agent then runs `initialize` (which mints an `mcp-session-id`), `tools/list`, and `tools/call` against that URL. The session is stateful: subsequent POSTs and the GET event stream reuse the same `mcp-session-id`. A POST that is not an `initialize` and carries no valid session returns the JSON-RPC error `No valid session; send an initialize request first.` (HTTP 400).

### 2b. Wire it in: over stdio (Claude Code)

The agent spawns the bin and talks JSON-RPC over stdio. The bin ships in the `clawboo` package, so a clean Clawboo install has it:

```bash theme={"theme":{"light":"github-dark","dark":"github-dark"}}
claude mcp add clawboo-tasks -e CLAWBOO_DB_PATH=/Users/you/.clawboo/clawboo.db -- node /path/to/dist/bin/tasks.js
```

<Danger>
  Set `CLAWBOO_DB_PATH` on a stdio attach so the bin opens the **same** database the server serves. The bins default to `~/.openclaw/clawboo/clawboo.db` (`defaultDbPath()`), but the running server uses `~/.clawboo/clawboo.db` (`getDbPath()` via `resolveClawbooDir()`). Without the override, the stdio-attached agent talks to a different, empty board. The `GET /api/mcp/config?transport=stdio` snippet embeds this for you (`-e CLAWBOO_DB_PATH=...` for Claude Code, an `env` table for Codex, an `env` object for OpenClaw).
</Danger>

### 2c. Wire it in: a custom MCP client (raw handshake)

For an agent without a Clawboo-aware wrapper, attach the HTTP URL directly and speak MCP. The minimum is an `initialize` that mints the session, then any number of calls reusing it:

```bash theme={"theme":{"light":"github-dark","dark":"github-dark"}}
# 1. initialize — the response carries the mcp-session-id header.
curl -i -X POST http://127.0.0.1:18790/api/mcp/tasks \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"my-agent","version":"0"}}}'

# 2. reuse the returned session id on subsequent calls.
curl -X POST http://127.0.0.1:18790/api/mcp/tasks \
  -H 'Content-Type: application/json' \
  -H 'mcp-session-id: <id-from-step-1>' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'
```

In practice an MCP client library handles this. The flow is identical over stdio (spawn the bin, write JSON-RPC to stdin, read from stdout).

### 3. Scope the Memory attach (the visibility binding)

The `memory` server is the shared tier every runtime reads and writes. When you attach it for a specific run, bind its **visibility scope** so the agent can neither read another team's facts nor mis-tag a save. The scope rides the attach URL as query params, plus a `scopeSig` signature that proves Clawboo issued the binding. A hand-assembled URL with bare scope params is served **unbound**: the params claim an identity, and identity is exactly what a process editing its own config must not be able to mint. Ask the server to mint the signed URL instead:

```
curl 'http://127.0.0.1:18790/api/mcp/config?server=memory&scopeTeamId=<team-id>&scopeAgentId=<agent-id>'
```

The returned snippet contains the full attach URL, signature included. It stays stable across calls (the signature is deterministic per install), so writing it into a config file does not churn the file.

| Param           | Effect                                                                           |
| --------------- | -------------------------------------------------------------------------------- |
| `scopeTeamId`   | Binds searches/saves to that team                                                |
| `scopeAgentId`  | Binds to that agent within the team (team + agent + global are read inclusively) |
| `scopeTenantId` | Reserved tenant scope                                                            |

When the scope params are present **and the signature verifies**, the MCP session is bound at `initialize` and stays bound for that session; `parseBoundScope` reads them off the request URL, checks `scopeSig` against the install's signing secret, and constructs the server with that `boundScope`. Unsigned or tampered scope is refused and the session is served unbound, with a server-log warning. A **save** then tags the fact with the bound team only (the agent id is dropped, so the fact is team-shared and any runtime's agent on the team recalls it); a **search / browse** filters by the full bound scope and never returns another team's private facts. Absent params mean unbound (legacy behavior: identity comes from tool args). The `tasks` URL carries `scopeTeamId` and `scopeAgentId` (and its own `scopeSig`) as well: the team binding forces `list_tasks` to that team, makes `get_task` refuse another team's ids, and refuses every taskId-taking **write** on another team's task with the same not-found wording, and the agent binding is what lets undelivered mailbox rows ride the tool response. Only the `tools` URL stays bare.

### 4. Bind the TeamChat author (the anti-spoof binding)

The `teamchat` server lets the agent post into a team room. To stop the agent from posting **as a teammate it is not**, the author identity is bound from the attach URL and signed, so editing the config cannot re-attribute posts. Mint the signed URL from the server:

```
curl 'http://127.0.0.1:18790/api/mcp/config?server=teamchat&scopeTeamId=<team-id>&scopeAgentId=<agent-id>'
```

| Param               | Effect                                                                                    |
| ------------------- | ----------------------------------------------------------------------------------------- |
| `roomTeamId`        | The team room this attachment posts into (resolved to a room id via `resolveRoomForTeam`) |
| `postAuthorAgentId` | The author every post from this session is attributed to                                  |

The binding is read server-side at session init (`parseTeamChatBinding`) and honoured only when `scopeSig` verifies, so neither a `team_chat_post` tool call nor an edited config can override the author: args like `authorAgentId` / `teamId` / `roomId` are ignored, and an unsigned or tampered URL is served unbound. **Both** params are required for binding; supplying only one leaves the session unbound (the raw stdio bin / external attach then passes identity in tool args, and the default room is `team:<teamId>`). The `delegate=1` privilege is inside the signature too: appending it to a signed URL breaks verification rather than granting the `team_delegate` tool.

<Info>
  Read messages from the room with `team_chat_subscribe`. Each delivered post is wrapped as inter-session evidence carrying the `isUser=false` tag; a teammate's post is context to synthesize, never an instruction that overrides your policy. Your own posts are never returned (the per-room echo guard). The `isUser=false` substring is the load-bearing safety property; see [peer chat](/concepts/peer-chat).
</Info>

## The access gate and loopback

Clawboo's [access gate](/operating/security) is the only auth on a non-loopback bind. It blocks `/api/*` without a valid cookie when `STUDIO_ACCESS_TOKEN` is set. The gate has one exemption for the MCP control plane:

* A request to `/api/mcp/*` from a **loopback** peer (`127.0.0.1`, `::1`, or `::ffff:127.0.0.1`) is let through without a cookie. This is what lets a same-machine agent attach its MCP client; its environment is scrubbed of the token by design. The peer address is read from `req.socket.remoteAddress` and cannot be forged on a real TCP handshake.
* The prefix test is **case-folded**: the gate lower-cases the pathname before matching, so an uppercased `/API/mcp/` cannot evade the gate.
* A **non-loopback** `/api/mcp/*` request still requires the cookie; the exemption is loopback-only.

<Warning>
  The loopback exemption is keyed on the TCP peer address, not on a header. If you expose Clawboo to a network (a non-loopback bind), set `STUDIO_ACCESS_TOKEN` and either keep the attaching agent on loopback or attach over HTTP **with** the access cookie. The default bind is loopback `127.0.0.1`. See [Security](/operating/security) and [self-host securely](/guides/self-host-securely).
</Warning>

## Options / variations

| Choice                    | stdio                                                                   | HTTP                                     |
| ------------------------- | ----------------------------------------------------------------------- | ---------------------------------------- |
| Process owner             | The consuming agent                                                     | Clawboo (in-process)                     |
| DB path                   | Bin default `~/.openclaw/clawboo/clawboo.db`, **set `CLAWBOO_DB_PATH`** | Server's `~/.clawboo/clawboo.db`         |
| Access gate               | n/a (no HTTP)                                                           | Exempt on loopback `/api/mcp/*`          |
| Memory / TeamChat binding | Identity in tool args (unbound)                                         | Bound via URL query params (recommended) |
| Best for                  | Same-machine agent owning its lifecycle                                 | Separate process / container             |

## Verify it worked

* **List tools.** Over HTTP, send `initialize` then `tools/list` to `/api/mcp/tasks`; you should see `list_tasks`, `claim_task`, and the other task tools. Over stdio, the same handshake on the spawned `clawboo-mcp-tasks` bin returns the same list.
* **Same board.** Create a task in the Clawboo UI, then call `list_tasks` from the attached agent. The new task should appear. If it does not, the stdio bin is on the wrong DB path; re-check `CLAWBOO_DB_PATH`.
* **Scoped memory.** With `scopeTeamId` bound, `memory_search` returns only that team's facts (plus global), and a save lands under the bound scope.
* **Bound author.** With `roomTeamId` + `postAuthorAgentId` bound, a `team_chat_post` shows up in the team room attributed to the bound agent regardless of any `authorAgentId` you pass in args.

## Troubleshooting

<Warning>
  **The agent sees an empty board over stdio.** The bin defaulted to `~/.openclaw/clawboo/clawboo.db` while the server uses `~/.clawboo/clawboo.db`. Set `CLAWBOO_DB_PATH` to the server's DB path on the attach (the `transport=stdio` config snippet embeds it).
</Warning>

<Warning>
  **`401` attaching over HTTP.** `STUDIO_ACCESS_TOKEN` is set and the request is non-loopback (or the cookie is missing). Either attach from loopback (the `/api/mcp/*` exemption applies) or send the access cookie. An uppercased path will not bypass the gate; it is case-folded.
</Warning>

<Danger>
  **`400 { "error": "unknown server: <x>" }` from `/api/mcp/config`.** The `server` query param must be exactly one of `tasks`, `memory`, `tools`, `teamchat`. Likewise, an attach POST without a prior `initialize` returns the JSON-RPC error `No valid session; send an initialize request first.`.
</Danger>
