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 testwell-mcp https://www.test-well.com/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 testwell-mcp --url https://www.test-well.com/mcp

Cursor

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