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 JSON object listing matching MCP servers or A2A tools relevant to the query, including their names, capabilities, and routing metadata, filtered through a Prompt-Guard firewall to prevent prompt injection attacks.
Example use cases
Discover tools for GitHub security
“Search the swarm router for any available MCP servers or A2A tools that can audit GitHub repositories for license risk and supply-chain vulnerabilities.”
Route query to compression agent
“Find me an MCP tool in the meta-router index that does context compression — I need to slim down long documents before passing them to my downstream agent.”
Verify an unknown agent endpoint
“Can you check the swarm router to see if https://some-agent.example.com/v1/tool is a known, compliant A2A endpoint and what capability it advertises?”
Technical details
Endpoint
POSThttps://json-repair.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover which of 500+ MCP servers or A2A tools can handle a specific capability, rather than hardcoding tool URLs. Ideal for dynamic agent orchestration pipelines where the right downstream tool is not known in advance. Prefer over manual tool registries when you need token-compressed, firewall-guarded routing in a single API call.
Side effects
- Empty or too-vague query string returns no matches or low-confidence results
- Unknown endpoint URL passed as query may return unverified or empty result
- Firewall may block or flag queries that resemble prompt injection attempts
- Payment failure via x402 returns HTTP 402 with no result
- Upstream MCP servers may be offline, returning partial or stale index data
