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://llms-generator.agentdiet.dev/v1/swarm-router)
Output
Returns a list of matching MCP servers or A2A tool endpoints from a 500+ server index, with token-compressed capability descriptions (85% compression), Prompt-Guard firewall filtering applied, and routing metadata to connect agents to the discovered tools.
Example use cases
Discovering tools for lead enrichment
“Search the MCP swarm router for any A2A or MCP tools that can do B2B lead enrichment or company data lookup — I want to see what's available before I wire up my agent pipeline.”
Finding a safe proxy for GitHub security audits
“I need my agent to audit GitHub repos for security issues — can you search the swarm router for MCP servers that handle GitHub security scanning and route me to the best one?”
Routing to on-chain risk analysis tools
“Look up the swarm router index for any MCP or A2A endpoints that cover on-chain risk or blockchain transaction analysis — list the matches with their capability summaries.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool supports a given capability at runtime, rather than hardcoding tool lists. Ideal for swarm orchestration, meta-routing pipelines, or when the set of available tools is large and changes frequently. Prefer this over direct MCP server calls when you need token-compressed discovery across 500+ tools in a single query, or when you need the Prompt-Guard firewall to screen tool metadata before routing.
Side effects
- Empty query string returns validation error (query is required, minLength 1)
- No matching tools found for obscure or misspelled capability queries
- Payment required (HTTP 402) if x402 USDC micropayment not provided
- Firewall (Prompt-Guard) may block queries containing adversarial or injection-like content
- Downstream MCP servers may be offline, causing partial or empty results
