Connect SpeedCurve to Codex

Use KosmoKrator as a local MCP proxy for Codex so coding sessions can reach selected integrations with explicit write policy.

Register kosmo mcp:serve as a local stdio server and choose the integration allowlist. The gateway is local, scoped to this integration, and starts with --write=deny so Codex can inspect read-capable tools without receiving write access by default.

SpeedCurve MCP Config for Codex

Keep write access denied or ask-based unless the workspace is trusted.

Why Use KosmoKrator Here

Scoped tools

Expose only SpeedCurve instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.

SpeedCurve Tools Visible to Codex

Codex sees stable MCP tool names generated from the SpeedCurve integration catalog.
