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/x402-gateway)
Output
Returns a structured, token-compressed (up to 85% reduction) list of matching MCP servers or A2A tools with capability descriptions, endpoint metadata, and safety status from the Prompt-Guard firewall. Results are filtered for prompt-injection risk before delivery.
Example use cases
Discover tools for a coding agent pipeline
“Search the tool index for 'github security' and 'dependency audit' capabilities — I'm building a coding agent and need to know which MCP servers or A2A tools can handle repo scanning.”
Find context compression tools for token savings
“Look up 'context compression' in the MCP tool discovery index — I want to find servers that can reduce token usage for my swarm and see their summaries.”
Verify an endpoint before routing agent traffic
“Can you check whether the endpoint at https://some-mcp-server.example.com is indexed and safe to proxy through the tool router? I want to confirm it passes the prompt-injection firewall before I send agent traffic there.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability, rather than hard-coding tool references. Especially useful for swarm orchestration, multi-agent routing, and when token budget is tight (85% compression). Prefer over manual tool registries when you need real-time index search across 500+ servers with built-in prompt-injection safety screening.
Side effects
- Query too vague — returns no matching tools or overly broad results
- Endpoint URL provided for verification is not indexed — returns not-found status
- Payment not processed (x402) — 402 response blocking result delivery
- Query matches tools that have since gone offline — stale index entries
- Firewall flags result payload as unsafe — response withheld or flagged
