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://onchain-risk.agentdiet.dev/v1/swarm-execute)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers or A2A tools from a 500+ entry index, including tool descriptors, routing endpoints, and capability metadata, with up to 85% token compression applied to the response.
Example use cases
Discover tools for GitHub security auditing
“Search the MCP tool index for anything that can do GitHub security audits — I need to find an agent or server I can route to for that capability.”
Find on-chain risk analysis agents
“I need to route to an MCP server or A2A tool that handles on-chain risk or DEX token intelligence — can you search the swarm router and tell me what's available?”
Locate email verification MCP endpoint
“Search the A2A and MCP tool index for an endpoint that can verify email addresses — I want to pick the best one to plug into my workflow.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability without hardcoding individual server URLs. Prefer it over manual tool registries when you need token-efficient metadata, built-in prompt injection protection, or a single connection point routing to 500+ tools across diverse domains like SEC filings, GitHub audits, on-chain risk, and lead enrichment.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability keyword
- Prompt-Guard firewall blocks query flagged as adversarial input
- Downstream MCP server unavailable causing partial results
- x402 payment failure prevents execution ($0.01 per call required)
- Query too generic returns overwhelming or unfocused result set
