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://workflows.agentdiet.dev/v1/mesh/dispatch)
Output
Returns a compressed index of matching MCP servers and A2A tools relevant to the query, including capability summaries, endpoint references, and safety-filtered metadata. Responses are token-compressed at approximately 85% to minimize context usage.
Example use cases
Discovering tools for SEC filing retrieval
“Search the MCP mesh for any tools that can pull SEC filings or EDGAR data — I need to find which servers support that capability so my agent can route calls to them.”
Finding on-chain risk analysis agents
“Look through the A2A and MCP index for tools that handle on-chain risk or smart contract security — I want to know what's available before I build my DeFi workflow.”
Locating email verification endpoints
“Search the tool discovery mesh for any MCP servers or A2A agents that do email verification or lead enrichment — list what's available with their capability summaries.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding tool endpoints. Ideal for swarm orchestration, dynamic workflow construction, or when building meta-agents that need to route sub-tasks to specialized tools without pre-knowing all available endpoints. The 85% token compression makes it particularly useful when operating under tight context window budgets.
Side effects
- Missing or empty query string returns a 400 validation error
- Query matches no indexed tools resulting in an empty result set
- Payment not attached triggers HTTP 402 requiring x402 micropayment
- Prompt injection detected by Prompt-Guard firewall blocks malicious queries
- Upstream MCP server unavailable causes partial result set
- Rate limiting on high-frequency swarm routing calls
