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://workflows.agentdiet.dev/v1/swarm-router)
Output
A compressed, Prompt-Guard-firewall-screened list of matching MCP servers and A2A tools from the 500+ server index, including tool names, capability summaries, and routing metadata — delivered with up to 85% token compression relative to raw tool catalogs.
Example use cases
Discovering SEC filing tools for agents
“Search the A2A and MCP tool index for anything related to 'SEC filings' — I need to find which servers in the swarm can pull financial disclosures so my agent can use one.”
Verifying a suspicious MCP endpoint
“Can you run this endpoint URL through the swarm router's safe-proxy check to verify it's not malicious before my agent starts using it? The URL is https://example-mcp-server.dev/tools.”
Finding company enrichment capabilities
“Search the meta-router for MCP servers and A2A tools that support 'company enrichment' — I want to see what's indexed and available with token-compressed results so I can wire one into my workflow.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability without maintaining its own tool registry. Ideal for orchestrators building swarm pipelines, agents needing token-efficient tool catalogs, or workflows requiring pre-screened, firewall-validated tool references before invocation.
Side effects
- No matching tools found for the query — returns empty results set
- Query string too vague or ambiguous — returns broad or irrelevant tool listings
- Endpoint URL verification fails if the target is unreachable or malformed
- Rate limit or x402 payment failure if the $0.01 per-call fee is not satisfied
- Firewall blocks results if indexed tools contain suspected prompt injection content
