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://github-audit.agentdiet.dev/v1/swarm-execute)
Output
Returns matched MCP server endpoints and A2A tools relevant to the query, along with routing metadata, compressed token output (up to 85% reduction), and Prompt-Guard firewall validation status. The response is a generic JSON object containing discovered capabilities and proxied results.
Example use cases
Discover tools for GitHub security audits
“I need to find which MCP servers or A2A tools in the swarm can audit a GitHub repository for security issues — search for 'github security audit' and tell me what's available.”
Route a DeFi yield analysis query
“Search the swarm router for any tools that can scan DeFi yield opportunities or stablecoin APYs — I want to know what's indexed and get the results back with token compression enabled.”
Find email verification tools via meta-router
“Can you query the swarm router with 'email verification' to discover which MCP tools or agents are available for validating business email addresses, so I can pick the best one?”
Technical details
Endpoint
POSThttps://github-audit.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to multiple AI tools, MCP servers, or A2A agents through a single API call rather than managing dozens of individual connections. It is best suited for agent orchestration pipelines that need dynamic tool selection, token-efficient responses, and built-in prompt injection protection. Prefer it over direct MCP server connections when you want a unified discovery layer with firewall safety.
Side effects
- No matching tools found for the query — returns empty results or low-confidence matches
- Query string too vague or too short — may return irrelevant or broad tool matches
- Prompt-Guard firewall blocks the query as potentially unsafe — returns a rejection notice
- Downstream MCP server unavailable — proxy routing fails for specific tools
- Payment not fulfilled via x402 — request blocked before tool discovery executes
- Idempotency-Key collision causing repeated results from a cached prior call
