Read-only MCP tools for session state and published research
What it is
A remote Model Context Protocol server that exposes completed-session market state and a library of published research notes. Five read-only tools return analog ranges and tape for a symbol, a daily note, a calibration receipt, a search over publications, and a paged read of one document. Agents and analysts can call the public HTTPS endpoint without an API key, or run the Python command client against that same service. Omitting the date returns the latest published session rather than a live quote, missing evidence is left missing, and keyword search ranks documents rather than market similarity.
