mcp-my-site

Point it at your website and ChatGPT, Claude and any other MCP client can search and read it.

A command-line indexer crawls the site and builds a hybrid keyword and vector index. A small
ASP.NET Core app serves that index as an MCP server with search and fetch tools, and as a JSON
search API for the site's own search box. One site per server, built for sites under 1,000 pages.

Try it now

A live instance indexes pournasserian.com:

claude mcp add --transport http pournasserian https://ai.pournasserian.com/mcp

Then ask Claude Code something about the site. For ChatGPT, add the endpoint as a connector; the
tools follow the search and fetch contract its connectors expect.

Quick start

You need the .NET 10 SDK. Nothing else: the first index is
keyword-only, so no API key is involved.

dotnet tool install --global mcpmysite
mcpmysite init https://example.com --keyword-only   # writes appsettings.json
mcpmysite build                                     # crawls the site into ./index
mcpmysite search "how can I contact you"            # checks the index
docker run --rm -p 5000:8080 -v "$PWD/index:/index:ro" -e Index__Path=/index ghcr.io/pournasserian/mcp-my-site:latest

Without Docker, clone the repository and run the server from source with
Index__Path=index dotnet run --project src/McpMySite.Server from the clone, or publish it
(user guide). The indexer also runs from a clone as
dotnet run --project src/McpMySite.Indexer -- ..., which is how to try unreleased changes.

The server is now at http://localhost:5000: /mcp for agents, /playground to try it in the
browser, /api/search?q=contact for JSON, /healthz for the loaded index.

claude mcp add --transport http mysite http://localhost:5000/mcp

Upgrade to hybrid search. Keyword search matches words; hybrid search also matches meaning, and
is what the live instance runs. It needs an API key for an OpenAI-compatible embeddings endpoint,
OpenRouter by default or another provider; the key is read
from AI_API_KEY and never written to a file. A small site embeds for a fraction of a cent.

export AI_API_KEY=sk-...
# in appsettings.json, under Embeddings, change "Enabled": false to true, then rebuild and serve
mcpmysite build
docker run --rm -p 5000:8080 -v "$PWD/index:/index:ro" -e Index__Path=/index -e AI_API_KEY ghcr.io/pournasserian/mcp-my-site:latest

Windows PowerShell and cmd, Docker without .NET on the host, and other MCP clients (VS Code,
Cursor, Claude Desktop) are in the user guide.

Features

• Hybrid search. BM25 keyword search and vector search over embeddings, fused per query, with a
  keyword-only fallback when the embedding provider is unavailable.
• Works without a key. A keyword-only index needs no embeddings provider at all; switch to
  hybrid search later with one setting and a rebuild.
• ChatGPT and Claude ready. Streamable HTTP MCP endpoint with search and fetch tools in the
  shape ChatGPT connectors use, and server instructions generated from the site itself. Works with
  Claude Code, Claude Desktop, VS Code, Cursor and the MCP Inspector.
• Search API for your own site. GET /api/search with CORS, rate limiting, an OpenAPI 3.1
  document and an interactive reference. Drop-in snippet for a search box in the
  user guide.
• Playground. /playground is a small MCP client in the page, so anyone can try the server
  without installing anything.
• Docker image. docker pull ghcr.io/pournasserian/mcp-my-site:latest; mount the index or
  point it at a URL.
• Hot swap. The server polls the index source and swaps in a new build without a restart.
• Telemetry. OpenTelemetry traces, metrics and logs to Application Insights or any OTLP
  collector. Query text is not logged unless you turn it on.
• Any embeddings provider. OpenRouter by default; any OpenAI-compatible endpoint works.
