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://agentdiet.dev/v1/tool-broker)
Output
Returns a compressed list of matching MCP servers and A2A tool endpoints from a 500+ service index, including routing metadata, tool descriptions, and compatibility information, delivered with 85% token compression through the Prompt-Guard firewall proxy.
Example use cases
Swarm router tool discovery
“I'm building a multi-agent swarm and need to find all available MCP servers that handle web scraping or data extraction — can you query the tool broker with 'web scraping extraction' and show me what's indexed?”
Finding crypto or DeFi agent tools
“Search the AgentDiet tool broker for any A2A or MCP tools related to DEX trading, token analysis, or on-chain data so I can route my DeFi agent to the right service.”
Single-connection multi-tool lookup
“Instead of connecting to dozens of MCP servers separately, use the tool broker to find me everything available for natural language processing and summarization tasks in one shot.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover which MCP servers or A2A tools exist for a given task without connecting to each individually. It is the right choice when building swarm architectures, when you want to minimize token usage via compression, or when you need a firewall-filtered proxy layer between your agent and untrusted tool servers. Prefer this over direct MCP server connections when the tool landscape is unknown.
Side effects
- Query string missing or empty — returns no results
- Unsupported HTTP method — only GET/POST accepted
- No matching tools found for the query — empty result set
- Downstream MCP server unavailable — proxy timeout or error
- Payment not confirmed via x402 — 402 Payment Required response
