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://company-enrich.agentdiet.dev/v1/execute)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers or A2A tools from an index of 500+, including tool metadata, capability descriptions, and endpoint references — delivered with up to 85% token compression relative to raw tool manifests.
Example use cases
Discovering a context compression tool
“Search the MCP tool index for anything that does context compression — I want to find a server I can route my agent through to cut down on token usage.”
Finding a GitHub security audit tool
“Look up MCP servers or A2A tools that handle GitHub security audits — I need to wire one into my pipeline to scan repos automatically.”
Routing agent to SEC filings capability
“Find me an MCP tool in the index that can pull SEC filings so my agent can look up earnings reports without me setting up a separate integration.”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover and route to the right MCP server or A2A tool from a large index without manually maintaining a tool registry. It is especially useful in swarm architectures where the correct downstream capability is not known in advance, or when token budget is constrained and compressed tool metadata is needed. Prefer this over hardcoded tool lists or manual MCP directory browsing.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- No matching tools found for obscure or misspelled capability query — returns empty result set
- Prompt-Guard firewall blocks queries detected as adversarial — returns rejection response
- Endpoint URL verification query for a non-compliant URL may return null or error metadata
- Payment failure via x402 if USDC balance is insufficient — returns 402 Payment Required
