## Install

```sh

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

It was fun while it lasted! Fathom now has an offical mcp: https://developers.fathom.ai/mcp-docs

However, I plan on adding very customizable tools to this mcp so it will be kept alive and expanded on once I have time or if anyone else contributes.

---

## Get Started

This server is published to the [MCP Registry](https://registry.modelcontextprotocol.io) as `io.github.agencyenterprise/fathom-mcp-server`.

### Claude Desktop (Streamable HTTP)

Connect in under 60 seconds:

```
https://www.fathom-mcp-server.com/mcp
```

1. Open **Claude Desktop**
2. Go to **Settings > Connectors > Add Custom Connector**
3. Paste the URL above
4. Authenticate with Fathom

That's it. Ask Claude about your meetings.

> **Organizations**: Admins must add the connector via organization admin settings, not personal settings.

### Perplexity Desktop and other SSE clients

For clients that use the legacy SSE transport (such as Perplexity Desktop for Mac), use the SSE endpoint:

```
https://www.fathom-mcp-server.com/sse
```

Refer to your client's documentation for how to add a remote SSE connector.

### Custom MCP Tools

#### `search_meetings`

Search Fathom meetings by title, meeting title, host name, host email, or attendee name/email. Automatically scans up to 5 pages of results. This is an MCP-native tool that performs client-side filtering since Fathom's API doesn't provide a search endpoint.

See the [Fathom MCP Server documentation](https://www.fathom-mcp-server.com/docs) for full request and response parameters.

### Example Usage in Claude

> "Show me my meetings from last week"

> "Get the transcript from my standup yesterday"

> "Summarize my meeting with the design team"

## Security

**Your Fathom data is never stored or exposed by this server.**

| Data                             | Stored? | Exposed? | Details                                                  |
| -------------------------------- | ------- | -------- | -------------------------------------------------------- |
| Meetings, transcripts, summaries | No      | No       | Fetched from Fathom and passed directly to Claude        |
| Team and member info             | No      | No       | Fetched from Fathom and passed directly to Claude        |
| OAuth tokens                     | Yes     | No       | Encrypted at rest (AES-256-GCM), never logged or exposed |

- **Pass-through architecture**: This server acts as a secure proxy, your Fathom data flows directly from Fathom to Claude without being stored, cached, or logged
- **Encryption at rest**: The only stored data (OAuth tokens) is encrypted using AES-256-GCM before being written to the database
- **HTTPS only**: All communication between Claude, this server, and Fathom is encrypted in transit

See our full [Privacy Policy](PRIVACY.md) for details on data collection, usage, and your rights.

## Permissions

This MCP server defines a custom scope called `fathom:read` for tokens it issues to Claude. This is not a Fathom API scope - it's specific to this MCP server to describe read-only access to your Fathom data.

The Fathom API itself only provides read access via its `public_api` scope. Write operations (creating/editing meetings, transcripts, etc.) are not available in the Fathom API.

## Limitations

- `search_meetings` performs client-side filtering since Fathom's API doesn't provide a search endpoint. For users with many meetings, use `list_meetings` with date filters instead.
- You can always ask the LLM what query params are avaialable.

## Self-Hosting

Fathom OAuth apps require HTTPS redirect URIs, so local development with `http://localhost` isn't possible. Deploy to a hosting provider to test.

### 1. Deploy to a Hosting Provider

Railway (recommended), Render, or any platform that provides:

- Node.js 18+ runtime
- PostgreSQL database
- HTTPS URL

**Railway setup:**

1. Fork/clone this repo
2. Create a new Railway project (you can deploy directly from your forked Github repo)
3. Add a PostgreSQL database service in project
4. Connect Database url to deployed repo in project and setup other envs

### 2. Create a Fathom OAuth App

1. Go to [Fathom Developer Portal](https://developers.fathom.ai/oauth)
2. Click "Register your app" (requires Fathom admin access)
3. Set the redirect URI to `https://your-app-url.railway.app/oauth/fathom/callback`
4. Note your Client ID and Client Secret

### 3. Configure Environment Variables (locally and in Railway)

Set these in your hosting provider's dashboard (as well as your local .env file to test build and start commands locally before pushing changes)

| Variable               | Description                                                            |
| ---------------------- | ---------------------------------------------------------------------- |
| `DATABASE_URL`         | PostgreSQL connection string (auto-set by Railway - use public db url) |
| `BASE_URL`             | Your app's public URL (e.g., `https://your-app.railway.app`)           |
| `TOKEN_ENCRYPTION_KEY` | 32-byte hex key (generate with `openssl rand -hex 32`)                 |
| `FATHOM_CLIENT_ID`     | From step 2                                                            |
| `FATHOM_CLIENT_SECRET` | From step 2                                                            |

### 4. Initialize Database

Run migrations after first deploy:

```bash
npm run db:migrate
```

Or via Railway CLI:

```bash
railway run npm run db:migrate
```

### 5. Connect Claude

Add your deployed URL as a custom connector in Claude Desktop:

```
https://your-app.railway.app/mcp
```

For SSE clients (Perplexity Desktop, etc.):

```
https://your-app.railway.app/sse
```

## Development

```bash
npm run dev          # Start dev server with hot reload only for testing
npm run build        # Build for production
npm run start        # Run production build
npm run lint         # Check for linting errors
npm run lint:fix     # Fix linting errors
npm run typecheck    # Run TypeScript type checking
npm run ci           # Run all CI checks (lint, typecheck, test, build)
npm run format       # Format code with Prettier
npm run db:studio    # Open Drizzle Studio for database inspection
npm run db:generate  # Generate migrations from schema changes
npm run db:migrate   # Run pending migrations
npm run db:push      # Push schema directly (dev only)
```

> **Tip**: Run `npm run ci` before pushing to ensure your changes pass GitHub Actions.

## Beta Testing

For pre-release features, use the staging URLs:

```
https://fathom-mcp-staging.up.railway.app/mcp
```

```
https://fathom-mcp-staging.up.railway.app/sse
```

## Future Development Plans

- **Transcript vectorization** — Enable vectorization of large transcripts so LLMs can parse and understand them more efficiently. Would be implemented as a stateless worker to ensure no user data is persisted.
- **Action item aggregation** — Aggregate action items across meetings with filters. "Show all my incomplete action items from this week."
- **Meeting analytics** — Calculate stats like total meeting time, meeting frequency, and top attendees.
- **Speaker time analysis** — Analyze transcripts to show who spoke most in a meeting.
- **Meeting comparison** — Compare two meeting summaries to highlight what changed over time.
- **Fathom API changelog monitoring** — Automated detection of Fathom API changes via GitHub Action that periodically checks their API reference and creates an issue if changes are detected.

Contributions toward these goals are welcome. See [CONTRIBUTING.md](CONTRIBUTING.md).
