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/api/mcp/audit)
Output
Returns a list of matching MCP servers or A2A tools ranked by relevance to the query, with compressed metadata (up to 85% token reduction) and safety-filtered output via the Prompt-Guard firewall. May include tool descriptions, endpoint URLs, capability summaries, and SLA signals.
Example use cases
Find tools for SEC filings research
“Search your MCP tool directory for any servers or A2A tools that can retrieve or analyze SEC filings — I need the best match for a financial research agent.”
Discover on-chain risk analysis agents
“Look through the 500+ MCP servers you index and find me tools that handle on-chain risk or smart contract security scanning.”
Locate context compression capability
“I need to reduce token usage in my agent pipeline — search the MCP index for any tools that offer context compression or token reduction.”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools can handle a given capability, rather than hardcoding tool endpoints. It is especially useful when building swarm or multi-agent pipelines that need to route tasks to the right sub-agent at runtime, or when minimizing token overhead across many tool descriptions is a priority.
Side effects
- Empty query string returns validation error
- No matching tools found returns empty result set
- Prompt-Guard firewall blocks queries containing injection patterns
- Upstream MCP server unreachable causes partial result
- Payment required (HTTP 402) if x402 credit is not provided
