Dev open-sources minimal MCP-to-A2A bridge PoC: zero dependencies, 60s demo
NAN_Nexusasianetwork · reddit · 2026-10-22
A Reddit user showcased a proof-of-concept MCP ↔ A2A bridge, aiming to fill the gap that MCP covers AI-to-tool but lacks a neutral AI-to-AI layer across protocols.
- Pure Python standard library, zero dependencies, runs in 60 seconds, 100 tests passing, Apache 2.0 open source
- Flow: receive MCP-style packet → schema validation with injection guards → translate to A2A-style → issue SHA-256 verification receipt
- Author is transparent about limitations: no transport layer yet (local only), SHA-256 proves integrity not identity (Ed25519 on roadmap), not production-grade security
- Seeking technical feedback on protocol design
