mcp-my-site: Turn Any Website into an MCP Server with .NET, Hybrid BM25+Vector Search
pournasserian · reddit · 2026-10-18
A Reddit user released mcp-my-site, an open-source .NET 10 project that turns any website into a remote MCP server so ChatGPT and Claude can search and read its content.
- How it works: a CLI (dotnet tool install --global mcpmysite) crawls the site and builds a search index; an ASP.NET Core app serves search and fetch tools over Streamable HTTP in the shape ChatGPT connectors expect, and doubles as a JSON search API for the site's own search box.
- Retrieval: hybrid BM25 + vector search over embeddings, fused per query; also runs keyword-only with no API key (the quick-start path).
- Scope: MIT licensed, designed for sites under 1,000 pages, one site per server. A live playground is available.
