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://json-repair.agentdiet.dev/v1/swarm-router)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed capability descriptions (up to 85% token reduction), safety/firewall status from the Prompt-Guard layer, and routing metadata for connecting to the identified endpoints.
Example use cases
Find tools for GitHub security audits
“Can you search the swarm router for any MCP servers or A2A tools that do GitHub repository security auditing? I want to know what's available before wiring up my coding agent.”
Discover company enrichment agents
“Look up what tools are indexed in the swarm router for B2B company enrichment — I need something that can pull tech stack and contact data for leads.”
Verify an endpoint before routing
“Check the swarm router to verify whether this endpoint URL is a known, safe MCP tool I can route traffic to: https://some-mcp-server.example.com/v1/tool”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover the right MCP server or A2A tool for a given capability without knowing which specific service to call — it acts as a universal directory and safe proxy. Prefer it over hardcoding individual MCP endpoints when you want token-efficient routing, firewall protection, or access to a broad index of 500+ tools from a single connection.
Side effects
- Empty or too-broad query returns too many low-relevance results
- Unknown or unindexed capability returns no matches
- Endpoint URL verification returns unrecognized or flagged result
- Prompt-Guard firewall blocks queries containing injected content
- Service unavailable if swarm index is being refreshed
- HTTP 402 payment required if x402 micropayment not included
