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://domain-osint.agentdiet.dev/v1/broker/execute)
Output
Returns a structured list of matching MCP servers or A2A tools that satisfy the capability query, including endpoint metadata, with 85% token-compressed responses and prompt-injection firewall screening applied.
Example use cases
Discover tools for on-chain risk analysis
“Search the A2A tool broker for any MCP servers or agents that can analyze on-chain risk or scan smart contracts for honeypot flags — I need to find what's available.”
Verify a specific endpoint URL exists
“Can you check whether https://some-mcp-server.example.com/v1/tool is listed and verified in the MCP tool index?”
Find compression or token-reduction tools
“Search the MCP broker for any tools that do context compression or token reduction for large language model inputs — I want to see what's indexed.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. Especially valuable in swarm or multi-agent orchestration scenarios where tool availability is unknown at design time, or when you need a safe-proxied single connection instead of managing 500+ individual tool connections.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability queries
- Endpoint URL verification returns not-found if URL is not indexed
- Rate limiting or payment failure via x402 if USDC balance is insufficient
- Malformed query may return empty or irrelevant results
