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 token-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches a meta-index of 500+ MCP servers and A2A agent tools by capability query, returning compressed, firewall-screened results for routing agent swarms to the right tool.

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://token-intel.agentdiet.dev/v1/workflows)
Output
A compressed list of matching MCP servers and A2A tools relevant to the query, with metadata about each tool's capabilities, filtered through the Prompt-Guard firewall and delivered at up to 85% token compression compared to raw listings.
Example use cases
Agent swarm capability routing
“I'm building a swarm of agents and need to find which MCP servers handle GitHub security audits — search the index and tell me the best options so I can route my agents there.”
Safe tool discovery for B2B enrichment
“Find me MCP or A2A tools that do B2B lead enrichment and company data lookups — I want results filtered through the Prompt-Guard firewall so I know they're safe to call.”
Endpoint verification for MCP URL
“Can you verify this MCP endpoint URL for me and tell me what capabilities it exposes and whether it's legitimate: https://some-mcp-server.example.com/tools”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool handles a given capability, especially within a multi-agent swarm where routing decisions must be made at runtime. Prefer it over hardcoding tool URLs when the ecosystem is large or changing, or when token budget is tight and compressed metadata is needed. Also useful for validating whether a specific MCP endpoint URL is real and compliant.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- No matching tools found for obscure or misspelled capability query
- Endpoint URL verification fails if the target URL is unreachable or malformed
- Rate limiting or payment failure via x402 if USDC balance is insufficient
- Stale index data if a listed MCP server has gone offline since last index update
