## Research notes
Verified 2026-09-07: POST of an MCP initialize to https://mcp.buffer.com/mcp returned HTTP 401 with {"error":"Authorization header is required","httpCode":401}, confirming a live auth-gated server, and the endpoint is printed verbatim in Buffer's own developer guide. THIS IS THE CHEAPEST OFFICIAL MCP SERVER FOUND IN THIS CATEGORY: a genuine free-forever plan carries a working API key and 3,000 requests a month, in a category where 12 of 16 prior entries had no MCP server at all and the ones that did were paid. That makes Buffer the natural bench-test candidate for this file. Rate limits are the thing to watch rather than the price: the guide states MCP calls "count against the same rate limits as any other client", on rolling 15-minute, 24-hour and 30-day windows, per client and shared across every request rather than counted per tool, so one chatty conversation that lists posts, reads several and edits one can spend a noticeable share of a free monthly allowance. Write access is in scope (schedule and edit posts), so an agent connected here can publish to real audiences. 2026-09-07: https://mcp.buffer.com/mcp returned 401 to an MCP initialize POST (https://mcp.buffer.com/mcp).
