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://mesh.agentdiet.dev/v1/workflows/rag-context-sanitizer)
Output
Returns a token-compressed list of matching MCP servers or A2A tools relevant to the query, including capability metadata, endpoint URLs, and safety/firewall status — with up to 85% token reduction compared to raw results.
Example use cases
Discovering tools for SEC filing analysis
“Search the MCP tool index for any available capabilities related to SEC filings or financial document retrieval so I can wire up the right tool for my research agent.”
Verifying a suspicious MCP endpoint URL
“Can you check this endpoint URL against the tool registry to verify it's a legitimate MCP server and not something that could inject malicious prompts into my agent?”
Finding B2B lead enrichment tools for agent swarm
“Search across all indexed A2A and MCP servers for any tools that do B2B company enrichment or contact lead extraction — I need to find the best one to plug into my prospecting workflow.”
Technical details
Endpoint
GEThttps://mesh.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 at runtime, especially when token budget is constrained or when the agent needs to validate an endpoint before calling it. Prefer this over hardcoded tool registries when the tool landscape is evolving or when prompt-injection safety screening is required.
Side effects
- Empty query string returns validation error
- No matching tools found for niche query returns empty result set
- Endpoint URL verification may fail if the target is unreachable
- Rate limiting or payment failure via x402 may block the request
- Malformed query may return generic or irrelevant results
