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://llms-generator.agentdiet.dev/v1/crypto-alpha-dag)
Output
Returns a compressed (up to 85% token reduction) list of matching MCP servers or A2A tools ranked by relevance to the query, including metadata such as endpoint URLs, capability descriptions, and firewall validation status from the Prompt-Guard layer.
Example use cases
Finding a crypto intelligence MCP tool
“Search the MCP meta-index for any tools that support on-chain risk or DEX token intelligence so I can wire them into my crypto trading agent.”
Locating a B2B lead enrichment agent
“I need to find an A2A tool or MCP server that does B2B lead enrichment and company data lookups — can you search the tool index for that capability?”
Verifying a specific MCP endpoint is safe
“Check whether https://some-mcp-server.example.com/mcp is listed in the meta-router index and passes the Prompt-Guard firewall before I connect my agent to it.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability without hardcoding tool lists — especially useful in swarm or meta-agent architectures where the set of available tools is large or changing, and when token budget is constrained (85% compression) or prompt injection risk is a concern.
Side effects
- Empty query string returns validation error
- Query matches no indexed tools, returning empty result set
- Endpoint URL verification fails if the target is not indexed
- Service may return stale index data if MCP servers have gone offline
- Payment (x402) not fulfilled results in HTTP 402 response blocking access
