InsumerAPI plugin for ChatGPT and Codex

The InsumerAPI plugin for the ChatGPT and Codex plugin directory: six skills plus a connection to the hosted InsumerAPI MCP server at https://api.insumermodel.com/mcp.

InsumerAPI is condition-based access infrastructure for blockchain wallets. Send a wallet and conditions, get a signed boolean across 37 chains, never the balance. Wallet auth is how it works: read, evaluate, sign.

Build

./build.sh

Vendors the five REST skills from a sibling checkout of insumer-agent-skills, validates the manifest limits, scans everything that will ship for secrets and internal names, and writes dist/insumer-plugin-<version>.zip. The ZIP is what gets uploaded to the plugin directory.

The hosted server

The MCP server is the same code as the mcp-server-insumer npm package, served over MCP streamable HTTP on a shared key. It serves ten tools that need no caller identity; the tools that produce signed results share one free daily allowance. For your own allowance, run the package locally with your own key.
