CoinGecko MCP Integration for Codex
Connect CoinGecko to Codex through the local KosmoKrator MCP gateway with scoped tools, credentials, and write policy.
Connect CoinGecko 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.
CoinGecko MCP Config for Codex
Keep write access denied or ask-based unless the workspace is trusted.

kosmokrator mcp:serve --integration=coingecko --write=deny Why Use KosmoKrator Here
Expose only CoinGecko instead of a broad multi-service tool list.
Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.
Start read-only, then opt into ask or allow for trusted workspaces.
