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/workflows/code-release-security-gate)
Output
Returns a compressed, firewall-filtered list of matching MCP servers or A2A tools from the 500+ indexed entries, including routing metadata, capability descriptions, and token-compressed summaries relevant to the search query or verified endpoint URL.
Example use cases
Discovering SEC filing tools for finance agent
“Search the A2A and MCP tool index for any servers that handle SEC filings or financial document retrieval — I need to route my finance agent to the right endpoint.”
Finding web distillation capability for research swarm
“Look through the MCP server index for tools that do web distillation or content summarization so I can connect my research swarm to the best available one.”
Verifying a specific MCP endpoint before use
“Can you check whether this URL is a valid, compliant MCP endpoint I can trust: https://example-tool.agentdiet.dev/v1/some-tool — I want to confirm it passes the prompt firewall before I route traffic to it.”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/workflows/code-release-security-gate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool provides a specific capability, rather than hardcoding a single tool. Especially useful for swarm architectures that need to route tasks to the best available tool at runtime, or when you want to verify an unknown endpoint for compliance and safety before use.
Side effects
- Empty or too-broad query returns too many low-relevance results
- Query for a niche capability returns no matches if not yet indexed
- Endpoint URL verification may return inconclusive results for non-standard implementations
- Payment failure (HTTP 402) if x402 USDC micropayment is not correctly handled
- Prompt injection attempts blocked by Prompt-Guard firewall, returning a rejection response
- Timeout if the index is temporarily unavailable or under load
