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 2026-10-23).
Searches an index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed metadata 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://token-intel.agentdiet.dev/v1/mcp-gateway)
Output
A paginated list of matching MCP servers and A2A tool entries, each including capability descriptions, endpoint URLs, and compressed metadata. Includes an opaque cursor for fetching subsequent pages. Protected by Prompt-Guard firewall to filter malicious tool outputs.
Example use cases
Discovering tools for SEC filing analysis
“Search the MCP tool index for any servers or A2A agents that can retrieve or analyze SEC filings — show me up to 20 results so I can wire one into my research workflow.”
Finding context compression MCP servers
“I need an MCP server that supports context compression to reduce token usage in my agent pipeline — can you search the tool index for 'context compression' and return the top 5 matches?”
Routing agent swarm to lead enrichment tools
“My agent swarm needs a tool for B2B company and contact enrichment — search the A2A and MCP registry for 'company enrichment' and give me the first page of results with their endpoint details.”

Endpoint
GEThttps://token-intel.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability, rather than hard-coding a specific tool. It is especially useful for agent orchestrators, swarm routers, or meta-agents that need to find and delegate to specialized tools at runtime, and when token efficiency (85% compression claim) and prompt injection safety (Prompt-Guard firewall) are priorities.
Side effects
- Empty query string returns validation error
- Query matches no indexed tools, returning an empty result set
- Cursor is invalid or expired, causing a pagination error
- Rate limiting or payment failure (x402) blocks access
- Index may be stale if newly added MCP servers have not yet been crawled
