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://polymarket-odds.agentdiet.dev/v1/swarm-execute)
Output
A JSON object listing matched MCP servers or A2A tool endpoints relevant to the capability query, with compressed metadata (85% token reduction) describing each tool's function, URL, and schema, filtered through a Prompt-Guard firewall for safety.
Example use cases
Finding a GitHub security audit tool
“I need to find an MCP server that can run a GitHub security audit on a repository — search the tool index for anything related to github security.”
Discovering company enrichment agents
“Can you search the swarm index for any A2A tools capable of B2B lead enrichment or company data enrichment?”
Locating a context compression endpoint
“Look up whether there are any indexed MCP tools for context compression or token reduction — I want to cut down my agent's token usage.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools exist for a given capability without maintaining your own tool registry, especially when token efficiency matters and you want a safety-filtered proxy layer over a large multi-tool index.
Side effects
- Empty query string returns validation error
- Query matches zero indexed tools — empty results array returned
- Indexed tool URLs may be stale or offline at time of proxying
- Overly broad queries may return low-relevance results
- x402 payment not honored causes 402 response with no results
