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/crypto-alpha-dag)
Output
Returns a token-compressed (up to 85% reduction) list of matching MCP servers or A2A tools relevant to the query, including tool descriptors and endpoint metadata, filtered through a Prompt-Guard firewall to remove malicious or unsafe results.
Example use cases
Discover tools for on-chain risk
“Search the tool index for any MCP servers or A2A agents that can do on-chain risk analysis or smart contract security scanning.”
Find context compression tools
“I need to find MCP endpoints that support context compression or token budget control — can you search the tool discovery router for that capability?”
Verify an endpoint before routing
“Can you check the tool discovery index to verify this endpoint URL and see if it's a legitimate, indexed MCP server: https://some-agent-tool.example.com/v1/tool”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without hard-coding tool lists, or when you want a single connection point to a large tool index with built-in token compression and safety filtering. Prefer it over manual tool registries when operating in swarm or multi-agent orchestration contexts where tool availability changes frequently.
Side effects
- Query returns no matching tools if the capability is too niche or not yet indexed
- Overly broad queries may return noisy or loosely-relevant results
- Payment required (HTTP 402) if x402 credentials are absent or insufficient
- Firewall may block results flagged as unsafe even if legitimate
- Endpoint URL verification may fail for servers not yet indexed
