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/bundle-execute)
Output
Returns a compressed list of matching MCP servers or A2A tools relevant to the capability query, including endpoint details and tool manifests, filtered through a Prompt-Guard firewall for safety. Results feature up to 85% token compression to reduce context overhead.
Example use cases
Discovering SEC filing retrieval tools
“Search the agent tool index for anything that handles SEC filings or EDGAR data — I need to find an MCP server my agent can call to pull company financials.”
Finding email verification endpoints
“Can you look through the MCP server index for tools that do email verification? I want to route my agent to a safe, token-efficient endpoint for validating contact lists.”
Locating on-chain risk analysis tools
“Search for A2A or MCP tools that cover on-chain risk or DEX token intelligence — I'm building an agent that needs to assess crypto wallet exposure before a transaction.”

Endpoint
GEThttps://github-audit.agentdiet.dev/v1/bundle-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hard-coding a specific tool. Especially useful when building swarm architectures, when the required capability may be served by multiple providers, or when token budget is constrained and compressed manifests are needed. Prefer this over direct MCP server lookup when safety filtering (Prompt-Guard) is required.
Side effects
- Empty result set if query term is too niche or no indexed tools match
- Prompt-Guard firewall may block or filter queries containing potentially malicious or injection-like content
- Rate limiting or payment failure (HTTP 402) if x402 payment is not properly attached
- Timeout if the meta-router cannot reach enough upstream MCP servers within SLA
- Malformed query returns validation error
