Dev launches hosted MCP server for US equity research with mandatory data dates and caveats
cplj777 · reddit · 2026-10-28
Developer cplj777 released Axiocairn, a remote MCP server (Streamable HTTP + OAuth, listed in the official MCP Registry as com.axiocairn/mcp) that lets agents find and read published US equity research: pre-market, midday, close reports, a weekly House View, and per-ticker reports.
The core design problem: agents are good at sounding current — ask what happened in the market today and you may get a confident answer built on yesterday's data. So the server enforces three rules:
- Every response carries the data date, separate from the publish date;
- Every report carries its limitations and missing fields, with tool descriptions instructing agents to keep caveats rather than summarize them away;
- Expected publish time ≠ availability — getreportschedule shows when a report should land, and tools plainly say when it hasn't.
Tools include gettodaysreports, searchreportarchive, gethouseview and more. Reports are free through Nov 1. The author is seeking client compatibility feedback (works in ChatGPT; testing Claude, Gemini, Grok, Copilot) and reliable techniques for making agents retain caveats across turns.
