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/paid)
Output
Returns a token-compressed listing of matching MCP servers and A2A tools ranked by relevance to the query, including tool names, capabilities, endpoint URLs, and firewall validation status. Results are filtered through a Prompt-Guard firewall to prevent injection risks.
Example use cases
Discovering tools for GitHub security audits
“Can you search the MCP tool registry for anything that does GitHub repository audits or code security scanning? I want to know what's available before I wire up my agent pipeline.”
Finding context compression agents
“My agent is running out of tokens — search the MCP index for any tools that do context compression or summarization so I can add one to my swarm.”
Verifying a specific endpoint before proxying
“Before I route my agent through it, check if https://some-mcp-server.example.com is a verified and safe endpoint in the MCP discovery index.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/paid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability, rather than hardcoding tool URLs. Especially useful for swarm orchestration, building dynamic agent pipelines, or safely proxying through unknown external MCP endpoints with firewall protection. Prefer this over manual MCP server lists when you want 85% token compression on tool metadata to preserve context budget.
Side effects
- Empty or too-broad query returns low-relevance results
- Endpoint URL verification returns not-found if the server is not indexed
- Malformed query string causes 400 bad request
- Payment not completed (HTTP 402) blocks access
- Rate limiting or timeout if index is under heavy load
