Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from json-repair.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed results and prompt-guard firewall protection.

How this service works
Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://json-repair.agentdiet.dev/v1/workflows)
Output
Returns a JSON object listing matching MCP servers or A2A tool endpoints relevant to the query, with token-compressed metadata (up to 85% compression), prompt-guard firewall status, and routing information for connecting to the matched tools.
Example use cases
Discover tools for company lead enrichment
“Search the tool meta-index for any MCP servers or A2A agents that can do B2B company or contact lead enrichment — use the query 'company enrichment' and list what you find.”
Route agent to context compression endpoint
“I need my agent to compress long prompts before sending them downstream — can you search for MCP tools that handle context compression and tell me which ones are available?”
Verify an endpoint for A2A compliance
“Check whether the endpoint at https://someprovider.example.com/v1/agent is a valid A2A or MCP endpoint by running it through the tool discovery router.”
Technical details
Endpoint
POSThttps://json-repair.agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, rather than hardcoding tool URLs. Especially useful in swarm or multi-agent architectures where tool availability changes frequently, or when you need safe-proxied access with built-in prompt firewall protection across 500+ indexed tools.
Side effects
- Empty or too-broad query returns no matches or overly generic results
- Queried endpoint URL is unreachable or non-compliant, returning validation error
- Token budget exceeded for large result sets
- Prompt-guard firewall blocks potentially adversarial query content
- x402 payment failure results in 402 response before routing occurs
- Service unavailability returns 5xx with no fallback routing
