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://mcp-security.agentdiet.dev/v1/tool-broker)
Output
Returns a token-compressed list of matching MCP servers or A2A tools relevant to the query, including capability metadata, endpoint references, and Prompt-Guard-screened payloads to protect against prompt injection in third-party tool responses.
Example use cases
Agent swarm tool discovery
“I'm building an agent swarm and need to find all indexed MCP tools that can do B2B lead enrichment — search the tool broker and list what's available with descriptions.”
Verify an MCP endpoint URL
“Can you check whether this endpoint URL is listed and verified in the tool broker index: https://mcp-security.agentdiet.dev/v1/sec-filings?”
Route agent to SEC filing capability
“My agent needs to pull 10-K filings — search the tool broker index for 'sec filings' and tell me which servers handle that so I can wire up the right connection.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover the right tool or MCP server at runtime rather than hardcoding a specific integration. Ideal for agent swarms that need to route capability requests across a broad catalog, or when building a meta-agent that orchestrates other specialized agents. The built-in 85% token compression and Prompt-Guard firewall make it preferable over raw MCP catalogs when token efficiency and injection safety both matter.
Side effects
- Empty query string returns validation error
- No matching tools found for niche query returns empty result set
- Endpoint URL verification returns not-found if URL not indexed
- Rate limiting or 402 payment required if usage quota exceeded
- Malformed query may return low-relevance results
