A2A Identity Toll MCP is a MCP server that enforces A2A caller identity and scope policy with verdict receipts and audit history.
About
A2A Identity Toll MCP is a Clauxel-hosted remote MCP server that acts as an identity and policy toll booth for agent-to-agent traffic—developers running multi-agent products use it when anonymous tool calls are no longer acceptable. Through streamable HTTP and a website-issued bearer token, the server evaluates caller identity against scope policy and returns verdict receipts backed by audit history, giving you evidence similar to a lightweight IAM review without building custom auth middleware first. It complements dependency inspection when both who is calling and what they depend on must be provable at Ship time. The surface is advanced: you need clear A2A roles, token management, and comfort wiring Authorization headers in MCP clients like Claude Code or Cursor. Skip it for single-user local experiments; adopt it when external or chained agents touch customer data or paid APIs.

What it does
Add A2A Identity Toll MCP so agents enforce caller identity, scope policy, and verdict receipts with auditable history for agent-to-agent traffic.
Who is it for?
Best when you're launching multi-agent or A2A integrations and need policy tolls and audit trails without a bespoke identity microservice.
Skip if: Single-agent local coding with no external callers, or teams satisfied with basic API keys only on human-facing REST endpoints.
What you get
After registering the remote MCP with a bearer token, your agent workflow gains identity checks, scope decisions, and auditable verdict receipts for A2A traffic.
- Caller identity and scope policy verdicts as structured receipts
- Audit history suitable for security and compliance review
- Production-ready remote MCP registration at version 1.0.0
By the numbers
- Server version 1.0.0
- GitHub repository clauxel/a2a-identity-toll-mcp
- Four publisher tags including agent-security and identity-policy
