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/rag-context-sanitizer)
Output
Returns a compressed, prompt-guard-filtered object containing matching MCP server and A2A tool records relevant to the query, with 85% token compression applied to reduce downstream LLM cost. Results may include tool names, capability descriptions, endpoint URLs, and safety verdicts.
Example use cases
Discovering GitHub security audit tools
“Find me any MCP servers or A2A tools in the index that can do GitHub security audits or code scanning — I want to know what's available and get a compressed summary I can use right away.”
Routing to context compression capability
“Search the tool discovery index for anything that supports context compression or token reduction — I'm trying to reduce prompt size before sending to my LLM.”
Verifying a remote agent endpoint
“Can you check whether this agent URL is listed and verified in your MCP index: https://some-agent.example.com/v1/tools — I need to know if it's a known, safe endpoint.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without hardcoding tool lists. It is especially useful when you want compressed, safe output (token-efficient, prompt-injection-filtered) for downstream LLM consumption. Prefer it over manual tool registries when working within a swarm or multi-agent architecture that needs real-time tool routing.
Side effects
- Empty query string returns validation error (query minLength:1 required)
- Query matches no indexed tools — returns empty result set
- Endpoint URL verification fails if URL not in index
- Payment not completed (HTTP 402) blocks response
- Prompt-Guard firewall may reject queries containing injection-like patterns
- Response schema is generic object — field names may vary or be undocumented
