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://agentdiet.dev/v1/mesh/dispatch)
Output
Returns a structured object listing matching MCP servers or A2A tool endpoints that satisfy the capability query, along with metadata such as tool descriptions, safety status from the Prompt-Guard firewall, and compressed tool manifests to reduce token overhead.
Example use cases
Discover tools for GitHub security audits
“Find me all available MCP servers or A2A tools in the mesh that handle GitHub security scanning or code auditing — I need to pick one for my automated pipeline.”
Route agent to context compression capability
“Search the tool mesh for any endpoints that support context compression or token reduction — I want to wire up my agent to one that can shrink my prompts before sending them to the LLM.”
Verify an MCP endpoint before use
“Can you check whether this URL is a valid, SLA-compliant MCP endpoint before I route my agent swarm to it: https://some-mcp-server.example.com/api/tools”
Technical details
Endpoint
GEThttps://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 tool to call for a given capability, rather than hard-coding a specific tool. It is especially useful for agent orchestration layers that need to route requests at runtime, want prompt-safety filtering before delegation, or benefit from compressed tool manifests to reduce LLM context usage.
Side effects
- Empty query string returns validation error
- No matching tools found for an obscure or misspelled capability query
- External MCP server index may be stale if recently updated
- Token compression may lose nuance in edge-case tool descriptions
- URL verification of a non-compliant endpoint returns error or timeout
