A2a Bridge
Let separate agents exchange messages and coordinate handoffs in a multi-agent coding or ops setup via MCP.
Overview
io.github.mdfifty50-boop/a2a-bridge is an MCP server for the Build phase that bridges agent-to-agent communication in multi-agent setups.
What is this MCP server?
- npm package a2a-bridge-mcp v0.1.1 with stdio MCP transport for local agent hosts
- Agent-to-agent communication bridge aimed at multi-agent system topologies
- stdio transport fits Claude Code and local MCP runners without hosting a remote gateway
- Open-source repo at github.com/mdfifty50-boop/a2a-bridge-mcp for inspection and forks
- Foundation layer for delegating subtasks between specialized agents instead of one monolithic prompt
- Published version 0.1.3 is costcenter sibling; a2a-bridge version 0.1.1
- npm identifier a2a-bridge-mcp with stdio transport
- Repository https://github.com/mdfifty50-boop/a2a-bridge-mcp
What problem does it solve?
Multi-agent workflows stall when each agent is isolated in its own MCP session with no structured way to pass context or tasks peer-to-peer.
Who is it for?
Builders prototyping multi-agent pipelines locally with npm-based MCP and stdio transport.
Skip if: Simple single-agent apps that do not need inter-agent messaging or production-grade enterprise agent buses.
What do I get? / Deliverables
You install a stdio MCP bridge so agents can coordinate through defined tools rather than manual copy-paste between terminal sessions.
- Running stdio MCP bridge process in agent config
- Tool surface for agent-to-agent coordination patterns
- Clearer separation of specialized agents in local workflows
Recommended MCP Servers
Journey fit
Agent-to-agent bridges are installed while composing multi-agent build stacks, not during idea research or post-launch SEO work. agent-tooling is the shelf for MCP servers that wire agents together rather than shipping app features or infra monitors.
How it compares
Local MCP stdio bridge for agent messaging, not a hosted todo service or billing dashboard.
Common Questions / FAQ
Who is io.github.mdfifty50-boop/a2a-bridge for?
Developers assembling multi-agent systems in Claude Code or similar hosts who need MCP-accessible agent-to-agent communication.
When should I use io.github.mdfifty50-boop/a2a-bridge?
Use it during build when you split work across multiple agents and need a bridge layer exposed as MCP tools over stdio.
How do I add io.github.mdfifty50-boop/a2a-bridge to my agent?
Install the npm package a2a-bridge-mcp, add a stdio MCP server entry pointing at that binary in your client config, and restart the MCP connection.
