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://mesh.agentdiet.dev/v1)
Output
Returns a token-compressed list of matching MCP servers or A2A tools relevant to the capability query, including metadata about each tool, its function, and endpoint details, all filtered through a Prompt-Guard firewall to prevent injection attacks in the returned tool descriptions.
Example use cases
Finding SEC filing tools for agent
“Search the tool mesh for any MCP servers or A2A endpoints that handle SEC filings or EDGAR document lookup — I want to add one to my research agent.”
Discovering prompt firewall capabilities
“Can you search the agent tool index for anything related to prompt injection detection or jailbreak protection so I can add a safety layer to my swarm?”
Locating token compression endpoints
“Look through the MCP index for tools that do context compression or token reduction — I'm running into context window limits and need something that gives around 80%+ compression.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which external MCP server or A2A tool to delegate a subtask to, especially when the agent doesn't have a hardcoded tool registry and needs runtime capability lookup across 500+ options with built-in safety filtering and token-efficient responses.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries
- Rate limiting or payment failure (x402) blocks access
- Firewall false positives may suppress legitimate tool results
- Overly broad queries may return noisy or low-relevance results
