How to connect POSTFACT — Resolve Ambiguous Side Effects Before Retry
POSTFACT — Resolve Ambiguous Side Effects Before Retry is a remote MCP server: there is nothing to install. Its endpoint is https://postfact-api-production.up.railway.app/mcp, served over Streamable HTTP. In an assistant that accepts remote MCP servers (often under a setting named connectors, integrations or tools), add a new server and give it this URL; in a client configured by file, add it as a remote (HTTP) server with the same URL.
No headers are declared in the registry entry. If the server needs you to sign in, a client that supports MCP authorization opens the service's own sign-in page when it first connects.
Derived from the registry entry, not tested here. What the server does, and on what terms, is set by its publisher; check its repository or website before giving it access to your accounts or files. How to add an MCP server to an assistant · Before you connect
