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 mes-frais-de-notaire-mcp https://www.mesfraisnotaire.fr/api/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 mes-frais-de-notaire-mcp --url https://www.mesfraisnotaire.fr/api/mcp
