Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from cve-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-28).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed results and prompt-guard firewall protection.

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://cve-intel.agentdiet.dev/v1/tool-search)
Output
Returns a list of matching MCP servers or A2A tool cards relevant to the search query, with token-compressed metadata, capability descriptions, endpoint URLs, and pricing information. Results are filtered through a Prompt-Guard firewall to block malicious tool descriptions.
Example use cases
Finding a web distillation tool for agent pipelines
“Search the tool index for an MCP server or A2A agent that can distill web URLs into compact token-efficient summaries — I want to add it to my swarm.”
Discovering SEC filing retrieval agents
“Find me any tools in the MCP ecosystem that handle SEC filings or financial document retrieval — search for 'sec filings' and show me what's available.”
Verifying a specific MCP endpoint is indexed
“Check whether the endpoint at https://example-mcp.dev/v1/tool is listed in the tool index and what capabilities it's registered for.”
Technical details
Endpoint
POSThttps://cve-intel.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or orchestrator needs to dynamically discover which MCP servers or A2A tools exist for a given capability — especially in multi-agent swarms where the right downstream tool is not known at build time. Prefer this over hardcoded tool lists when the ecosystem is large (500+ servers) and the agent needs to self-assemble a toolchain at runtime. The built-in 85% token compression and Prompt-Guard firewall make it safer than querying raw registries.
Side effects
- Empty or overly broad query returns too many low-relevance results
- Query for a very niche or newly registered tool may return no matches if not yet indexed
- Malformed query string (empty) rejected with validation error
- Payment/x402 authorization failure if funds are insufficient
- Endpoint URL verification may return not-found if the target is not indexed
