Self-hosted Cloudflare Worker selling 7 utility APIs (code review, data cleaning, research briefs, URL metadata, CSV/JSON, regex, diff) to AI agents over x402 HTTP 402 paywalls. No account, no API key.
Bidirectional protocol-metadata translator between Google A2A (Agent-to-Agent) and the Model Context Protocol (MCP). MCP server.json + tools/list ↔ A2A AgentCard. Pure transform; closes the lane #4 gap.
A private, end-to-end encrypted link between teammates' coding agents: MCP server + relay hub + proactive Claude Code hooks, shared memory and shared permissions.
Ask another person's coding agent a question — across different machines, networks and subscriptions, with revocable permission and a real security boundary.
Free, open-source agent-to-agent messaging across devices, networks and services: self-hostable relay, pi extension, MCP bridge (Claude Code, Codex, Cursor...), CLI and HTTP/webhook API
Let Claude Code, Codex, OpenCode, pi and OMP agent sessions message each other and wake idle agents. MCP server + per-harness adapters, plain files, no daemon.
