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://mesh.agentdiet.dev/v1/workflows/execute)
Output
Returns a token-compressed list of matching MCP servers and A2A tools relevant to the query, including capability descriptions, endpoint metadata, and safety status from the Prompt-Guard firewall — structured as a JSON object with 85% fewer tokens than raw discovery payloads.
Example use cases
Finding SEC filing tools for research agent
“Search the MCP tool index for anything that handles SEC filings or EDGAR data — I'm building a financial research agent and need to know which servers to connect to.”
Discovering context compression MCP servers
“I want to reduce token usage in my agent pipeline — can you search for MCP servers that offer context compression or token-diet capabilities?”
Verifying a suspicious A2A endpoint before use
“Before my agent calls this endpoint at https://some-tool.example.com, can you run it through the tool index to verify it's a known, safe MCP server and not something sketchy?”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover new MCP servers or A2A tools at runtime rather than using a hardcoded list — especially useful when the required capability is unknown in advance, when routing to the safest available proxy matters, or when token budget is constrained and 85% compression on discovery payloads is valuable. Prefer over manual registry searches or raw MCP directory scraping.
Side effects
- Empty or too-broad query returns low-relevance results
- Unknown or unindexed endpoint URL returns no verification match
- Payment not processed (402) blocks result delivery
- Query matches no indexed MCP server in the 500+ catalogue
- Malformed query string returns validation error
