## Features

Built on [`@cyanheads/mcp-ts-core`](https://github.com/cyanheads/mcp-ts-core):

- Declarative tool definitions — single file per tool, framework handles registration and validation
- Unified error handling across all tools
- Pluggable auth (`none`, `jwt`, `oauth`)
- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`
- Structured logging with optional OpenTelemetry tracing
- Runs locally (stdio/HTTP) or via Docker from the same codebase

OpenFEC-specific:

- Type-safe client wrapping the [OpenFEC REST API](https://api.open.fec.gov/developers/)
- Multi-mode tools supporting both itemized records and aggregate breakdowns
- Keyset cursor pagination for high-volume Schedule A/B/E data
- Automatic retry with configurable timeout and max retries
- Error sanitization strips API keys from error messages; HTTP status errors enriched with actionable hints
- Two guided investigation prompts for campaign finance analysis workflows

## Getting Started

### Public Hosted Instance

A public instance is available at `https://openfec.caseyjhand.com/mcp` — no installation required. Point any MCP client at it via Streamable HTTP:

```json
{
  "mcpServers": {
    "openfec-mcp-server": {
      "type": "streamable-http",
      "url": "https://openfec.caseyjhand.com/mcp"
    }
  }
}
```

### Self-Hosted / Local

Add the following to your MCP client configuration file.

```json
{
  "mcpServers": {
    "openfec-mcp-server": {
      "type": "stdio",
      "command": "bunx",
      "args": ["@cyanheads/openfec-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "FEC_API_KEY": "your-api-key"
      }
    }
  }
}
```

Or with Docker:

```json
{
  "mcpServers": {
    "openfec-mcp-server": {
      "type": "stdio",
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "MCP_TRANSPORT_TYPE=stdio", "-e", "FEC_API_KEY=your-api-key", "ghcr.io/cyanheads/openfec-mcp-server:latest"]
    }
  }
}
```

For Streamable HTTP, set the transport and start the server:

```sh
MCP_TRANSPORT_TYPE=http MCP
