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://serp-extract.agentdiet.dev/v1/swarm-execute)
Output
Returns a list of matching MCP servers and A2A tool endpoints relevant to the query, with token-compressed metadata (85% compression) and Prompt-Guard firewall screening applied. Results include tool names, capabilities, and routing information.
Example use cases
Find MCP tool for vulnerability scanning
“Search the swarm index for any MCP servers or A2A tools that can scan open-source packages for CVE vulnerabilities — I want to find what's available before picking one.”
Discover agents for on-chain risk analysis
“Can you query the MCP tool index and find me any A2A agents or tools that handle on-chain risk or smart contract security for Base or Solana?”
Route query to right email verification tool
“I need to verify business email addresses at scale — search the MCP swarm for tools that do email verification or B2B lead enrichment and tell me what's available.”

Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover the right tool or MCP server for an unfamiliar task, rather than hard-coding a specific API. Ideal for meta-orchestration, swarm routing, or building agent pipelines that need to self-discover capabilities at runtime. Preferred over manual MCP directory browsing when token efficiency and security (prompt injection firewall) matter.
Side effects
- Empty or vague query returns no meaningful matches
- Query string too short or malformed triggers validation error
- No MCP servers matching the query exist in the index
- Payment not completed via x402 results in 402 response
- Prompt injection attempt blocked by Prompt-Guard firewall returns error
