Build bridges between A2A and MCP — wrap A2A agents as MCP tools, use MCP tools from A2A agents, and architect hybrid multi-agent systems. Use when integrating A2A agent-to-agent communication with MCP tool access.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# A2A + MCP Bridge ## Before writing code **Fetch live docs**: 1. Fetch `https://a2a-protocol.org/latest/specification/` for the A2A protocol details 2. Web-search `a2a mcp integration bridge agent tool` for patterns combining the two protocols 3. Web-search `site:github.com a2aproject A2A MCP` for any official A2A-MCP integration examples 4. Web-search `site:modelcontextprotocol.io specification` for the latest MCP specification ## Conceptual Architecture ### A2A vs MCP — Complementary Protocols | Aspect | A2A | MCP | |--------|-----|-----| | **Purpose** | Agent-to-agent delegation | Agent-to-tool/data access | | **Participants** | Agents (opaque, autonomous) | Agent + tool server (transparent) | | **Communication** | Tasks with messages | Tool calls with structured I/O | | **State** | Long-lived tasks with lifecycle | Stateless tool invocations | | **Discovery** | Agent Cards | Server manifests | | **Transport** | JSON-RPC over HTTP | JSON-RPC over stdio/HTTP+SSE | ### Why Bridge Them Real-world multi-agent systems need both: - **A2A** for delegating complex, open-ended work to other agents - **MCP** for accessing specific tools, databases, APIs, and data sources …

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/a2a-mcp-bridge@sha256:f23b6d4b7340ae3bThe line at the top of this page pins the label git:20260309.786511c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
