A2a Governance Bridge Mcp
A2A Governance Bridge MCP is a security MCP server that verifies agent compliance, authorizes A2A transactions, and exposes trust context for governed multi-agent workflows.
About
A2A Governance Bridge is a Model Context Protocol server that exposes governance-oriented tools for multi-agent setups: verifying that agents meet compliance expectations, authorizing agent-to-agent transactions, and surfacing trust-related context (description truncates at trust retrieval). Developers shipping agent orchestrations—marketplaces, copilots that delegate to specialists, or internal tool agents—can register this server so coding agents invoke policy checks instead of improvising security. It installs as a stdio MCP server from PyPI under CSOAI-ORG’s io.github namespace, aligning with MCP’s 2025-12-11 server schema. You reach for it when A2A volume grows beyond a single trusted agent and you need repeatable guardrails before launch, not as a replacement for full IAM or enterprise GRC platforms.
- MCP tools to verify agent compliance against governance rules
- Authorize individual A2A transactions before they execute
- Retrieve trust or attestation context for participating agents
- Stdio MCP transport via PyPI package a2a-governance-bridge-mcp v1.1.5

What it does
Gate and audit agent-to-agent (A2A) calls from Claude Code or Cursor before production multi-agent workflows go live.
Who is it for?
Best when you're wiring Claude Code or similar agents into A2A-style delegation and need lightweight governance hooks at ship time.
Skip if: Skip if you only run a single local agent with no cross-agent RPC, or orgs that already mandate a full enterprise identity and GRC stack for every call.
What you get
Your agent can call MCP tools to verify compliance and authorize A2A actions so multi-agent flows stay policy-bound instead of trust-on-first-use only.
- Compliance verification results for registered agents via MCP tools
- Explicit authorization decisions on proposed A2A transactions
- Trust or attestation context surfaced to the coding agent during orchestration

FAQ
Who is A2A Governance Bridge MCP for?
Developers shipping multi-agent products who want compliance verification and A2A authorization wired into their coding agent via MCP.
When should I use A2A Governance Bridge MCP?
Use it in the Ship security subphase when agent-to-agent transactions need explicit authorization and trust checks before production rollout.
How do I add A2A Governance Bridge MCP to my agent?
Install the PyPI package a2a-governance-bridge-mcp, add a stdio MCP server entry in Claude Code or Cursor pointing at that package, then invoke the governance tools from the agent.
