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/agent-router)
Output
Returns a token-compressed (up to 85% reduction) list of matching MCP servers or A2A tools, their capability descriptions, and endpoint metadata, all filtered through a Prompt-Guard firewall to remove prompt-injection risks. May include endpoint verification status when a URL is submitted as the query.
Example use cases
Discover context compression tools
“I need to find MCP servers that support context compression for my AI pipeline — can you search the agent-router index and show me what's available?”
Verify a specific endpoint before use
“Before I connect to this endpoint at https://some-mcp-server.example.com/tool, can you check the agent-router to verify it's safe and tell me what capability it actually offers?”
Route swarm query to right tool
“My agent swarm needs to handle B2B lead enrichment tasks — search the meta-router for the best available A2A tools for company enrichment and give me a compressed list of options.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/agent-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which tools, MCP servers, or A2A agents exist for a given capability rather than hardcoding a specific tool. Especially valuable in swarm architectures, multi-agent pipelines, or when building tool-agnostic orchestration layers. Prefer this over direct endpoint calls when you want prompt-injection protection on third-party tool responses, or when you need token-efficient tool routing across a broad catalog of 500+ services.
Side effects
- Empty or vague query returns no meaningful matches
- Unknown or unindexed capability query returns empty results
- Endpoint URL verification fails if the target is offline or returns unexpected responses
- 402 payment required error if micropayment is not handled correctly
- Rate limiting if too many discovery requests are made in quick succession
