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 obolus-mcp https://www.obolusfinanz.de/api/mcp/public

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 obolus-mcp --url https://www.obolusfinanz.de/api/mcp/public
