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/a2a-router)
Output
Returns matched tool listings, capability metadata, and routed responses from indexed MCP servers and A2A agents, with up to 85% token compression applied and prompt-injection threats filtered by the Prompt-Guard firewall.
Example use cases
Discover tools for on-chain risk analysis
“Find me any MCP servers or A2A tools in your index that can analyze on-chain risk or DEX token data — I want to know what's available before I start building my crypto agent.”
Route agent query to best capability match
“My agent needs context compression right now — search your tool index for the best available MCP server that handles that and route my query there.”
Verify a specific endpoint is live and compliant
“Can you check whether https://json-repair.agentdiet.dev/v1/a2a-router is a valid, compliant A2A endpoint and tell me its capability metadata?”
Technical details
Endpoint
POSThttps://json-repair.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover, search, or route across a broad ecosystem of MCP servers and A2A tools without maintaining individual connections to each. Ideal for agents that need to find the right tool dynamically, want 85% token compression on aggregated results, or require a prompt-injection firewall before passing queries to third-party tools.
Side effects
- Empty or vague query returns no matches or low-confidence results
- Queried endpoint URL is unreachable or non-compliant, returning a validation error
- Token limit or compression failure if upstream tool response is malformed
- Payment required (HTTP 402) if x402 micropayment is not provided or fails
- No matching tools found for niche or unsupported capability queries
