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://mesh.agentdiet.dev/v1/tool-broker)
Output
Returns a compressed, token-efficient list of matching MCP servers and A2A tools relevant to the query, including capability descriptions, endpoint URLs, and metadata — filtered through a Prompt-Guard firewall to prevent injection attacks.
Example use cases
Finding a compression tool for swarm agents
“I'm building a multi-agent pipeline and tokens are getting expensive — search the tool broker for any MCP servers that do context compression or token reduction so I can route through them.”
Verifying a specific endpoint is indexed
“Can you check whether this endpoint URL is listed in the AgentDiet tool broker: https://mesh.agentdiet.dev/v1/github-audit — I want to confirm it's discoverable before I wire it into my agent.”
Discovering on-chain risk tools
“I need an A2A tool that can assess on-chain risk for crypto wallets — search the tool broker for anything related to blockchain risk, DeFi security, or DEX token intelligence.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to specialized tools or MCP servers at runtime without hardcoding dozens of individual API integrations. Ideal for swarm orchestrators, meta-agents, and agent frameworks that need a single connection point to 500+ tools with built-in prompt-injection protection and token-efficient responses.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability names
- Endpoint URL verification returns not-found if URL is not indexed
- Rate limiting or payment failure when x402 micropayment is not correctly handled
- Overly broad queries may return too many results without useful ranking
