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://mcp-compiler.agentdiet.dev/v1/x402-gateway)
Output
Returns a compressed list of matching MCP servers and A2A tools relevant to the search query, including capability descriptions, endpoint URLs, and metadata — with 85% token compression applied and prompt-injection-safe payloads, enabling the calling agent to route to the right downstream tool.
Example use cases
Discover tools for GitHub security auditing
“Can you search the MCP tool index for anything that does GitHub security audits or code vulnerability scanning? I want to find what A2A endpoints are available for that.”
Find on-chain risk analysis capabilities
“Search for MCP servers or agent tools that can do on-chain risk analysis or DEX token intelligence — I need to route my agent to the right capability.”
Verify a specific MCP endpoint is live
“Check whether this endpoint URL is a real, active MCP server: https://some-mcp-server.example.com/v1 — I want to confirm it's indexed and working before routing my agent there.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover the right downstream MCP server or A2A tool without knowing which one to call in advance, especially when operating across a large heterogeneous tool ecosystem. It is particularly valuable when token efficiency matters (85% compression), when safety from prompt injection in tool responses is a concern, or when you want a single connection point rather than managing hundreds of individual tool registrations. Prefer alternatives when you already know the exact MCP server URL to call directly.
Side effects
- Empty or vague query returns no useful matches
- Queried endpoint URL not indexed or unverifiable
- Token budget exceeded despite compression for very broad queries
- Payment not confirmed via x402 leading to 402 response blocking results
- Prompt-Guard firewall blocks a query that superficially resembles injection pattern
