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/a2a-mesh)
Output
Returns a compressed, token-efficient list of matching MCP servers and A2A tools, including endpoint URLs, capability descriptions, safety/firewall status, and routing metadata — filtered through a Prompt-Guard firewall to remove malicious or injection-risk entries.
Example use cases
Discovering context compression tools
“Search the A2A and MCP tool index for anything that handles context compression or token reduction — I need to find a server I can route my agent through to reduce prompt size.”
Finding SEC filings capability
“Look through the MCP server index for any tools that can pull SEC filings or 10-K reports — I want to know what's available before I build my financial research agent.”
Verifying a specific MCP endpoint
“Can you check whether this endpoint URL is listed and trusted in the MCP tool registry: https://some-provider.example.com/v1/mcp — I want to know if it's indexed and safe to use.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding specific tool URLs. Ideal for meta-agent orchestration, swarm routing, and situations where you want a safety-screened, token-compressed index of the MCP/A2A ecosystem in a single call.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- No matching tools found returns an empty result set
- Query too vague returns low-relevance or broad results
- Payment not processed (x402) results in 402 Payment Required response
- Upstream MCP index unavailable causes 503 or timeout
