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/mesh/dispatch)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the search query, with compressed metadata about each tool's capabilities, likely including tool names, endpoint URLs, capability descriptions, and routing information — filtered through a Prompt-Guard firewall to prevent prompt injection.
Example use cases
Finding GitHub security audit tools
“Can you search the MCP tool index for anything that handles GitHub security audits or code vulnerability scanning? I want to know what agents are available before I pick one.”
Discovering DEX token intelligence agents
“Search for MCP servers or A2A tools that can give me DEX token intelligence or on-chain token risk analysis — show me what's indexed.”
Routing to best email verification service
“I need to verify some business emails at scale — search the agent tool directory for MCP servers or A2A endpoints that specialize in email verification so I can route my requests there.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to dynamically discover which MCP server or A2A agent to call for a given capability, rather than hardcoding a specific tool. Ideal for agent orchestration pipelines that need to route tasks to the best available specialist tool from a large index, or when building swarm architectures that need to enumerate available capabilities before dispatching work.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability query
- Upstream MCP server index temporarily unavailable
- x402 payment failure blocks access
- Prompt-Guard firewall rejects query containing suspicious injection patterns
- Timeout if routing to slow downstream agents
