MCP support
Provides three tools to MCP clients through a local stdio package or a hosted Streamable HTTP endpoint. The tools read public data and require no credentials.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From the project READMEopencrater-mcp
An MCP server for OpenCrater — the monetization network for the terminal. Surface OpenCrater inside any MCP client (Claude Code, Codex, …): live network stats, supported AI tools, and how to start earning USDC from your own MCP server or CLI tool.
No credentials needed — every tool reads public data.
Tools
| Tool | What it returns |
|---|---|
opencrater_network_stats | Live network momentum — Blips delivered, developers reached, budget committed to creators, USDC earned by maintainers, supported tools. |
opencrater_supported_tools | The AI coding tools where OpenCrater Blips render. |
opencrater_get_started | How a maintainer starts earning USDC with OpenCrater. |
Install
Two ways to connect — a local stdio package, or the hosted remote endpoint.
Local (stdio, via npx)
npx opencrater-mcp
{
"mcpServers": {
"opencrater": {
"command": "npx",
"args": ["-y", "opencrater-mcp"]
}
}
}
Hosted (remote, Streamable HTTP)
No install — point any MCP client at the hosted endpoint:
https://opencrater.to/mcp
{
"mcpServers": {
"opencrater": {
"url": "https://opencrater.to/mcp"
}
}
}
Run from source
npm install
npm run build
node dist/index.js
Monetize your tool
If you maintain an MCP server or CLI tool, you can earn USDC with a single tasteful sponsored Blip at a natural pause — free to add, opt-out always a keystroke away. → https://opencrater.to/monetize

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
