a2aidentitytoll-mcp — Claude Code MCP server: what it does and setup
Remote gatekeeper for agent-to-agent interactions. It validates caller identity, enforces scope rules, and writes structured audit receipts.
claude mcp add --transport http a2aidentitytoll-mcp https://a2aidentitytoll.clauxel.com/mcpWhat a2aidentitytoll-mcp does
The server acts as a hosted gatekeeper between collaborating agents. When one assistant queries another, the tool verifies the caller credentials and task scope. It returns structured decisions in JSON alongside explanation details whenever a request gets rejected.
Five tools power the workflow: evaluate_a2a_identity_policy, review_agent_scope, issue_identity_receipt, explain_denied_call, and export_a2a_audit_log. They let your setup evaluate inbound calls, issue proof receipts, and extract audit records on demand.
This is a commercial remote service hosted at https://a2aidentitytoll.clauxel.com/mcp. Because the public repository contains guides rather than backend application code, running it requires an active paid account on the vendor platform.
What it helps with
- verify caller identity and task scope between interacting agents
- generate structured proof receipts for authorized calls
- diagnose why a specific agent call was denied
- export historical audit records for compliance inspection
Example prompts for the agent
- Verify incoming agent permissions with
evaluate_a2a_identity_policybefore processing the payload. - Check why the remote caller was rejected using
explain_denied_call. - Retrieve recent interaction logs with
export_a2a_audit_log.
