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://mcp-security.agentdiet.dev/v1/swarm-router)
Output
Returns a list of matching MCP servers and A2A tools from the 500+ indexed registry, with tool metadata, endpoint details, and token-compressed summaries — all filtered through the Prompt-Guard firewall to strip hidden injection attempts before surfacing results to the agent.
Example use cases
Discovering tools for crypto intelligence
“Can you search the swarm router for any indexed MCP servers or A2A tools that handle DEX liquidity analysis or on-chain token risk scoring?”
Finding prompt-safe email verification tools
“I need to find available agent tools for email deliverability checking — search the meta-router and make sure results are filtered through the prompt-guard firewall.”
Routing a capability query for GitHub audits
“Look up which MCP servers in the swarm router index support GitHub repository security auditing or dependency scanning — I want to pick the best one for my coding agent.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to discover the right tool for an unknown capability across a broad landscape of MCP servers and A2A APIs, especially when you want a single-connection entrypoint, 85% token compression on results, and built-in prompt-injection safety rather than manually curating tool lists or calling multiple registries.
Side effects
- Missing or empty 'query' parameter returns 400 validation error
- Query returns no matching tools if capability is not indexed
- Payment required (HTTP 402) if x402 credit not provided
- Prompt-Guard may suppress results flagged as injection attempts, returning fewer results than expected
- Upstream MCP server may be offline despite being indexed
