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/broker/execute)
Output
Returns a ranked list of matching MCP servers or A2A tools with compressed metadata (85% token reduction), safety flags from the Prompt-Guard firewall, and routing information for the best-matching capability given the query.
Example use cases
Discover tools for GitHub security audits
“Search across all available MCP servers and A2A tools to find ones that can do GitHub security auditing — I want a single connection that routes me to the best option.”
Route agent to context compression tool
“Find me an MCP tool in the index that handles context compression so my agent can reduce token usage on long documents.”
Verify a suspicious MCP endpoint URL
“Can you check if this MCP endpoint URL is safe and compliant before I let my agent call it? I want to run it through the Prompt-Guard firewall first.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover and route to one of many MCP servers or A2A tools without managing individual connections, especially when token budget is constrained or when safety screening of upstream tools is required. It is particularly useful for swarm architectures or orchestrators that need dynamic tool selection at runtime.
Side effects
- Query too vague returns broad or irrelevant tool matches
- Endpoint URL verification fails if the target is offline or non-compliant
- Firewall blocks results for endpoints flagged as prompt-injection risks
- Empty results if no indexed tool matches the capability query
- Timeout if the meta-router cannot reach upstream MCP servers in time
