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 1820-ch-mcp https://mcp.1820.ch/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 1820-ch-mcp --url https://mcp.1820.ch/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable 1820-ch-mcp in your MCP settings.
