# Attaching Clawboo's MCP servers

> Attach the four hosted MCP servers (tasks, memory, tools, teamchat) to an external agent over stdio or Streamable HTTP.

Use this page when you want an external agent to act as a teammate inside Clawboo: read and claim board tasks, search shared memory, call brokered tools, and post in a team room. Clawboo hosts four [MCP](/appendices/glossary) servers, `tasks`, `memory`, `tools`, and `teamchat`, and the agent attaches them as MCP clients. The agent does not need to be a Clawboo runtime; anything that speaks MCP can attach.

There are two transports for the same four servers:

* **stdio**: Clawboo ships four standalone bins (`clawboo-mcp-tasks`, `clawboo-mcp-memory`, `clawboo-mcp-tools`, `clawboo-mcp-teamchat`). The consuming agent spawns one as a child process and talks JSON-RPC over stdin/stdout. Best for an agent on the same machine that owns its own process lifecycle.
* **Streamable HTTP**: the running Clawboo server exposes the same four servers in-process at `/api/mcp/{tasks,memory,tools,teamchat}`. The agent connects over HTTP. Best when the agent is a separate process (or container) that talks to a long-running Clawboo.

Both transports read and write the **same SQLite database**, which is 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.

## Prerequisites

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

* The four stdio bins ship in the `clawboo` npm package (`bin` entries), so a clean Clawboo install has them. For HTTP, nothing extra is needed beyond a running server.
* The external agent must already speak MCP (initialize → `tools/list` → `tools/call`). The tool surface per server is in [MCP tools reference](/reference/mcp-tools).

## At a glance

| Server     | HTTP path           | stdio bin              | Example tools                                    |
| ---------- | ------------------- | ---------------------- | ------------------------------------------------ |
| `tasks`    | `/api/mcp/tasks`    | `clawboo-mcp-tasks`    | `list_tasks`, `claim_task`, `update_task_status` |
| `memory`   | `/api/mcp/memory`   | `clawboo-mcp-memory`   | `memory_save`, `memory_search`, `memory_browse`  |
| `tools`    | `/api/mcp/tools`    | `clawboo-mcp-tools`    | brokered tools (per descriptor)                  |
| `teamchat` | `/api/mcp/teamchat` | `clawboo-mcp-teamchat` | `team_chat_post`, `team_chat_subscribe`          |

Each HTTP path accepts `POST` (the JSON-RPC request body), `GET` (the SSE event stream for a session), and `DELETE` (session teardown). The session is keyed by the `mcp-session-id` header; the first request must be an `initialize`, which mints the session id returned on subsequent calls.

## Steps

### 1. Get an attach snippet (recommended)

Rather than hand-write config, ask Clawboo to emit it. `GET /api/mcp/config` builds a copy-pasteable attach block for a given 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 human copy-paste line; `structured` is the same attachment as an object (for programmatic config, e.g. 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`; these are the three the snippet builder knows how to format           |
| `transport` | `http`        | `http`, `stdio`                                                                                           |

<Note>
  The snippet builder formats config for `claude-code`, `codex`, and `openclaw` only. To attach from `hermes`, `clawboo-native`, or any other MCP-speaking agent, use the HTTP URL (`<base>/api/mcp/<server>`) or the `node <bin>` invocation directly; the structure is the same; only the per-runtime wrapper differs.
</Note>

For `transport=http`, the base URL in the snippet is the server's **own bound port**, resolved from `app.locals.apiPort`, never from 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` if the server was started with that env var (the CLI sets it for the bundled bins); otherwise it emits a `<path-to>/dist/bin/<server>.js` placeholder.

### 2a. Attach over HTTP

Point the agent's MCP client at `<clawboo-base>/api/mcp/<server>`. For Claude Code:

```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`.

### 2b. Attach over stdio

The agent spawns the bin and talks JSON-RPC over stdio. For Claude Code:

```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
```

<Info>
  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`, but the running server uses `~/.clawboo/clawboo.db` (under `resolveClawbooDir()`). Without the override, a stdio-attached agent would talk 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).
</Info>

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

The `memory` server is the shared tier every runtime reads and writes. When attached 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:

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

| Param           | Effect                              |
| --------------- | ----------------------------------- |
| `scopeTeamId`   | Binds searches/saves to that team   |
| `scopeAgentId`  | Binds to that agent within the team |
| `scopeTenantId` | Reserved tenant scope               |

When the scope params are present, the MCP session is bound at `initialize` and stays bound for that session. Absent params mean unbound (legacy behavior, identity comes from tool args). The `tasks` URL carries `scopeTeamId` and `scopeAgentId` too: the team binding forces `list_tasks` to that team and makes `get_task` refuse another team's ids, 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 an agent post into a team room. To stop an agent from posting **as a teammate it is not**, the author identity is bound from the attach URL, written by Clawboo, not passed in tool args:

```
http://127.0.0.1:18790/api/mcp/teamchat?roomTeamId=<team-id>&postAuthorAgentId=<agent-id>
```

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

Because the URL is Clawboo-written config and the binding is read server-side at session init, a `team_chat_post` tool call cannot override the author. When **both** params are present the session is bound; otherwise the attachment is unbound (the raw stdio bin / external attach passes identity in tool args). Both params are required for binding; supplying only one leaves it unbound.

## Options / variations

| Choice                    | stdio                                                                   | HTTP                                              |
| ------------------------- | ----------------------------------------------------------------------- | ------------------------------------------------- |
| Who owns the process      | The consuming agent (spawns + kills the bin)                            | Clawboo (long-running, in-process)                |
| Database path             | Bin default `~/.openclaw/clawboo/clawboo.db`; **set `CLAWBOO_DB_PATH`** | Server's `~/.clawboo/clawboo.db` (always correct) |
| Access gate               | n/a (no HTTP)                                                           | Exempt on loopback for `/api/mcp/*` (see below)   |
| Memory / TeamChat binding | Pass identity in tool args (unbound)                                    | Bind via URL query params (recommended)           |
| Best for                  | Same-machine agent owning its lifecycle                                 | Separate process / container                      |

## 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 a `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 runtime Clawboo spawned on the same machine attach its MCP client; its environment is scrubbed of the token by design.
* The prefix test is **case-folded**: the gate lower-cases the pathname before matching, so an uppercased `/API/mcp/` (or `/API/settings`) cannot evade the gate.
* A **non-loopback** `/api/mcp/*` request still requires the cookie; the exemption is loopback-only, and a remote client cannot forge a loopback source on a real TCP handshake.

<Info>
  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 attach over HTTP **with** the access cookie (or keep the attaching agent on loopback). See [Security](/operating/security) and [self-host securely](/guides/self-host-securely).
</Info>

## 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` should only return that team's facts (plus global). A save lands under the bound scope.

## Troubleshooting

<Warning>
  **stdio agent sees an empty board.** 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.** A `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 a JSON-RPC error ("No valid session; send an initialize request first").
</Danger>
