A2a MCP Server

A2A Governance Bridge MCP server. Tools: verify agent compliance, authorize a2a transaction,... Exposed over MCP by the a2a mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

A2A Governance Bridge MCP — compliance checking for agent-to-agent communications. Policy enforcement, audit trails. MIT.

Adding it to your client

@smithery/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Its toolset

Everything the assistant can do here goes through one of these:

• Well — documented API
• Production-ready — Active maintenance
• Pro — ** $99/mo — Full MCP suite + EU AI Act tracking
• Enterprise — ** $499/mo — Custom dev + SLA + Dedicated support
• Domain — Purpose
• Tier — Price

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the a2a mcp server does with a few real requests.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. A2a's toolset — Well, Production-ready, Pro and 3 more — is a fair guide to whether it matches your workflow. It is maintained by CSOAI-ORG; worth a glance at recent repository activity before you build anything load-bearing on it.
