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/web-rag-shield-dag)
Output
A structured list of matching MCP servers or A2A tools relevant to the query, with token-compressed summaries (up to 85% reduction) and prompt-guard-filtered responses. Results include tool names, capabilities, and routing information for connecting to the matched endpoints.
Example use cases
Discover tools for GitHub security auditing
“Find me any MCP servers or A2A tools in the index that can run GitHub security audits — I want the compressed results so I'm not burning tokens.”
Route SEC filing queries through safe proxy
“Search the tool registry for anything that handles SEC filings and route my query safely through the firewall proxy so I don't expose my agent to prompt injection.”
Find context compression capabilities
“I need to find MCP tools that do context compression — can you search the 500-server index and tell me what's available?”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover which MCP servers or A2A tools are available for a given capability without connecting to each server individually. It is especially useful when token budget is a concern (85% compression), when security against prompt injection is required (Prompt-Guard firewall), or when you want a single-connection router rather than managing many separate MCP connections.
Side effects
- Query string too vague returns low-relevance or empty tool matches
- Endpoint URL verification may fail if remote server is down or non-compliant
- Token compression may lose nuance for complex capability queries
- Prompt-Guard firewall may block legitimate queries that resemble injection patterns
- HTTP 402 payment required if payment not attached
