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://shopify-intel.agentdiet.dev/v1/workflows/rag-context-sanitizer)
Output
Returns a structured object containing matching tool or MCP server entries from a 500+ item index, with token-compressed metadata, Prompt-Guard-filtered context, and routing information suitable for direct agent consumption or swarm orchestration.
Example use cases
Discover tools for SEC filing retrieval
“Search the tool index for any MCP servers or A2A agents that handle SEC filings or financial document retrieval — I need to plug one into my research pipeline.”
Find a prompt-safe proxy for GitHub audits
“Look through the agent tool directory for something that can do GitHub security audits and runs through a prompt firewall so I don't have to worry about injection attacks.”
Route swarm agent to email verification tool
“My swarm agent needs to verify email addresses — search the MCP index for the best available tool for that and return its endpoint details and compressed metadata.”
Technical details
Endpoint
GEThttps://shopify-intel.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 server or A2A tool to use for a given capability at runtime, especially when token budget is constrained (85% compression) or when prompt injection safety is a concern. Prefer it over hardcoded tool registries when the tool landscape may change or when routing across a large multi-server swarm.
Side effects
- Empty or too-generic query returns low-relevance or no matches
- Query matches no indexed capability, returning empty result set
- Prompt-Guard firewall blocks a query flagged as potentially adversarial
- Endpoint URL verification query fails if the target is offline or non-compliant
- HTTP 402 payment required if x402 credentials are missing or invalid
