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/b2b-osint-dag)
Output
Returns metadata about matching MCP servers or A2A tools including endpoint details, capability descriptions, and token-compressed responses; protected by a Prompt-Guard firewall to prevent prompt injection from upstream tools.
Example use cases
Discovering tools for SEC filing retrieval
“Search the MCP tool index for any servers or A2A tools that can pull SEC filings or EDGAR data — I need to know what's available and how to connect.”
Routing to a GitHub security audit tool
“Find me an MCP server in the index that can audit GitHub repositories for security vulnerabilities — I want the best match with connection details.”
Finding company enrichment capabilities
“Look through the MCP and A2A tool registry for anything that does B2B company enrichment or lead data — I need to find a capable endpoint I can route my queries to.”
Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to MCP servers or A2A tools from a large indexed registry in a single connection, especially when token budget is a concern (85% compression) or when you need a safe proxy that guards against prompt injection from untrusted upstream tools. Prefer over manual MCP server enumeration or direct multi-connection swarm setups.
Side effects
- Empty or too-vague query string returns no matches or overly broad results
- No indexed servers match the requested capability, returning an empty result set
- Prompt-Guard firewall may block or sanitize certain query patterns flagged as injection attempts
- Downstream MCP server unavailable causing routing failure
- Malformed query (minLength not met) returns a 400 validation error
- Payment not satisfied returns HTTP 402 with x402 payment challenge
