I just did a fresh pass over every API provider in my network — 6201 repos in the API Evangelist Network — looking for explicit evidence that each provider ships an MCP (Model Context Protocol) server. The bar I used: either an official repo in the company’s own GitHub organization with mcp in the name (attributed back to the specific product, not a sister product), or a first-party blog announcement on the company’s own domain whose title both names the company and uses an announcement verb (introducing, announcing, now generally available, etc.). No third-party tutorials, no “how-to-build-with-MCP” posts, no sister-product attribution. That filter surfaced 199 providers with an MCP server. Below they are grouped by the first tag each provider declares for itself in its apis.yml. 162 sit in tag groups of three or more; the remaining 37 are collected at the bottom under “Other”. The links go directly to the MCP repo or announcement post and to my catalog, so you can verify each one against the source.
