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://github-audit.agentdiet.dev/v1/execute)
Output
Returns a structured object listing matching MCP servers and A2A tools with compressed metadata, capability summaries, and endpoint details relevant to the search query, filtered through a Prompt-Guard firewall to prevent prompt injection from tool descriptions.
Example use cases
Discover SEC filing tools for agent
“Search the tool index for any MCP servers or A2A agents that handle SEC filings or financial document retrieval — I want to know what's available before wiring up my research agent.”
Route context compression capability
“Find me an MCP server in the index that does context compression or token reduction — I need to cut down my agent's token usage and want to know what tools are available.”
Verify endpoint before integration
“Can you check if this URL is a valid registered endpoint in the tool index: https://example-mcp-server.dev/v1 — I want to confirm it's there and compliant before I start using it.”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP or A2A tools are available for a given capability at runtime, rather than hard-coding tool integrations. Particularly useful when orchestrating swarms of agents that need to self-select tools, or when verifying whether a known endpoint URL is indexed and compliant. Prefer over manual tool registries when you need 500+ tools searchable in a single call with built-in safety filtering.
Side effects
- Empty query string returns validation error
- No tools found for niche capability query returns empty result set
- Endpoint URL verification returns not-found if URL is not indexed
- Rate limiting or x402 payment failure if micropayment not settled
- Malformed query may return generic or irrelevant results
