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://defi-yield.agentdiet.dev/v1/tool-search)
Output
Returns a list of matching MCP servers or A2A tool entries relevant to the capability query, with compressed metadata (85% token reduction) and Prompt-Guard firewall filtering applied, indicating which tools are available, their endpoints, and their capabilities.
Example use cases
Discovering tools for financial data
“Search for MCP servers or A2A tools that handle SEC filings or financial document retrieval — I want to find what's available so my agent can pull earnings reports.”
Finding a prompt safety firewall tool
“Can you search the tool index for any MCP or A2A endpoints that do prompt injection protection or prompt firewall filtering? I need one I can route my swarm through.”
Locating GitHub audit capabilities
“Find me any available MCP servers or agent tools that can do GitHub security audits or code vulnerability scanning — search the tool directory for 'github security'.”
Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/tool-search?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, rather than hard-coding tool endpoints. Ideal for swarm orchestration scenarios where the right tool is not known in advance, or when you need a safe-proxied, token-compressed single-connection interface to hundreds of tools at once.
Side effects
- Empty result set if the query matches no indexed tools
- Query too vague or broad may return low-relevance results
- Endpoint URL verification may fail if the remote server is offline
- Payment required (HTTP 402) if x402 micropayment header is missing or insufficient
- Malformed query string returns validation error
