# API Keys and Scribe MCP
## API Keys
API keys let external tools access your Fable data without a browser session. Each key is scoped to a single user — it can only access data that user owns or has been shared with them.
### Scopes
| Scope | Permissions |
|-------|-------------|
| `read` | GET endpoints only — list, search, fetch content |
| `write` | Full read + create, update, delete |
Admin-level operations (log access, user management) require a `write`-scoped key from an admin account.
### Creating a Key
1. Go to **Settings → API Keys**
2. Enter a name (e.g. "Claude MCP", "Home Server")
3. Choose scope
4. Click **Generate Key**
5. Copy the key immediately — it is shown only once (the token is `fmcp_`-prefixed)
Paste the key into the `Authorization: Bearer <key>` header of your MCP client
config (see **Scribe MCP Server** below).
### Revoking a Key
Click **Revoke** next to the key in the API Keys table and confirm. Revoked keys are deleted immediately.

## Scribe MCP Server
Scribe exposes itself as a set of MCP tools that Claude (and other MCP clients)
can use to read and write your notes, tasks, projects, rulebooks, and more. The
server is **built into the app** — it is mounted as a streamable-HTTP endpoint
at **`/mcp`** on the running Scribe instance (`src/scribe/mcp/server.py`). There
is nothing to install: no wheel, no separate package, no CLI. You connect a
client straight to the URL with a Bearer token.
### Authentication
Authenticate with an API key generated from **Settings → API Keys** (see above),
sent as `Authorization: Bearer fmcp_<key>`. A `read`-scoped key may call only the
read tools (`get_*`, `list_*`, `search`, `enter_project`, `retrieval_telemetry`);
any write/delete tool is rejected with `403`. The allow-list is explicit rather
than derived from the name — see `_READ_ONLY_TOOLS`, which is why the two reads
without a read-shaped name are spelled out here. A `write`-scoped key may call everything.
### Claude Code (Project-scoped)
Add a `.mcp.json` at the project root. The server `type` is `http` and the URL is
your instance's `/mcp` endpoint:
```json
{
"mcpServers": {
"scribe": {
"type": "http",
"url": "https://your-scribe-instance.example.com/mcp",
"headers": {
"Authorization": "Bearer fmcp_your-api-key"
}
}
}
}
```
Note: `.mcp.json` contains an API key and should be added to `.gitignore`.
### Claude Code (Global)
The same `mcpServers` block can live in `~/.claude.json` to make the server
available across all projects. A project-scoped `.mcp.json` takes precedence over
the global entry when both define the same server name — useful for pointing a
specific project at a dev instance or an admin key.
### Available Tools
The tool surface is large (~70 tools) and evolves with the app, so the live
registration in **`src/scribe/mcp/tools/`** is the source of truth rather than a
table here. The tools are grouped by family:
| Family | Examples | Purpose |
|--------|----------|---------|
| Notes | `create_note`, `get_note`, `update_note`, `delete_note`, `list_notes` | Free-form knowledge |
| Tasks | `create_task`, `update_task`, `add_task_log`, `start_planning` | Actionable work + plans |
| Projects / Milestones | `enter_project`, `get_project`, `create_milestone`, … | Containers and outcomes |
| Search / Recall | `search`, `get_recent`, `list_tags`, `retrieval_telemetry` | Semantic + structured recall, and the readout its thresholds are tuned from |
| Systems | `create_system`, `list_systems`, `list_system_records` | Reusable per-project subsystems/areas |
| Rulebooks | `list_rules`, `create_rule`, `create_project_rule`, `subscribe_project_to_rulebook`, … | Engineering/workflow rules |
| Processes | `list_processes`, `get_process`, `create_process` | Saved prompts/workflows |
| Trash | `list_trash`, `restore`, `purge_trash` | Recoverable deletes |
| Admin | `get_app_logs` (write/admin key) | Diagnostics |
Server-level usage guidance — when to reach for each entity, the
recall-before-acting reflex, and the rulebook conventions — is delivered to the
client automatically via the MCP server's `instructions` block (defined in
`src/scribe/mcp/server.py`).
