Occam MCP MCP server

Occam is a remote MCP server that performs symbolic regression on numerical data to discover governing mathematical equations. It supports SINDy for differential equations and PySR for algebraic relationships, returning results ranked by simplicity and accuracy.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http occam-mcp https://occam.fit/mcp/

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add occam-mcp --url https://occam.fit/mcp/

Cursor

Merge this server into .cursor/mcp.json in your project, then enable occam-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "occam-mcp": {
      "url": "https://occam.fit/mcp/"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "occam-mcp": {
      "type": "streamableHttp",
      "url": "https://occam.fit/mcp/",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start occam-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "occam-mcp": {
      "type": "http",
      "url": "https://occam.fit/mcp/"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http occam-mcp https://occam.fit/mcp/

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "occam-mcp": {
      "url": "https://occam.fit/mcp/"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "occam-mcp": {
      "serverUrl": "https://occam.fit/mcp/"
    }
  }
}
