# InsumerAPI plugin for ChatGPT and Codex

The InsumerAPI plugin for the ChatGPT and Codex plugin directory: eight 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

```bash
./build.sh
```

Vendors the seven REST skills from a sibling checkout of [insumer-agent-skills](https://github.com/insumerapi/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](https://github.com/insumerapi/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.
