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/workflows/execute)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with results compressed to reduce token usage and filtered through a Prompt-Guard firewall to remove prompt-injection risks. Response is a generic JSON object with discovered tool metadata.
Example use cases
Finding a tool for SEC filings
“I need to pull SEC filings data for a public company — can you search the MCP tool index for something that handles SEC filings and return the best match?”
Safe-proxied GitHub security audit
“Search for an MCP or A2A tool that does GitHub security audits or repo vulnerability scanning, and make sure the result is filtered through the prompt-guard firewall before you show me.”
Discovering email verification tools
“My agent needs to verify email deliverability — search across all indexed MCP servers for a tool that handles MX records, SPF, or DMARC validation and tell me which one to use.”
Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to dynamically discover which MCP server or A2A tool supports a given capability across a broad index of 500+ options, especially when token efficiency and prompt-injection safety are priorities. Prefer this over hard-coding specific tool URLs when your agent's required capability is unknown at design time or when you want a single connection point for multi-tool orchestration.
Side effects
- Empty or vague query returns no relevant tools
- Query matches no indexed server (no results found)
- Firewall blocks response if prompt injection detected in upstream tool output
- Payment required (HTTP 402) if x402 credits are insufficient
- Timeout if upstream MCP server is unresponsive
- Malformed query schema returns validation error
