Using the service
Metro MCP is an unofficial community project. It is not affiliated with or endorsed by WMATA, MTA, OpenAI, Anthropic, or any transit agency. You may use it to retrieve public, read-only transit information through its website, server-information endpoint, and MCP tools. The service does not sell tickets, control transit operations, or modify agency data.
Live data has limits
WMATA and MTA control the availability and accuracy of their upstream feeds. Results can be delayed, incomplete, inaccurate, unavailable, omitted, stale, or changed by the agencies without notice. Metro MCP can also be interrupted by network, edge-platform, deployment, or maintenance events.
Fair use and rate limits
Please use reasonable request rates. Abuse, disruption, attempts to circumvent service protections, and unlawful use are prohibited. Avoid automated traffic that disrupts the service or its upstream providers. Metro MCP uses abuse controls and rate limits, currently configured at roughly 300 requests per 60-second window per source-IP key per Cloudflare location. Shared networks can share that allowance, and enforcement is eventually consistent.
Requests may be refused, throttled, or limited to protect the service, other users, and upstream systems. The policy can change as operational needs change.
Third-party services and data
Use of Cloudflare, GitHub, WMATA, MTA, MCP clients, and transit data remains subject to applicable third-party service and data-source terms. Metro MCP does not replace those terms.
No warranty
Metro MCP is provided “as is” and “as available,” without warranties of availability, accuracy, fitness for a particular purpose, or non-infringement. To the extent permitted by law, the project author is not liable for losses arising from use of, inability to use, or reliance on the service or its data.
