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/workflows/execute)
Output
Returns a compressed (85% token reduction) listing of matching MCP servers and A2A tools from the 500+ item index, filtered through a Prompt-Guard firewall, including endpoint metadata, capability descriptions, and verified connection details.
Example use cases
Finding SEC filings MCP tool
“Search the MCP tool index for anything that can fetch or analyze SEC filings — I need to find the right agent endpoint for financial document research.”
Discovering email verification agents
“Can you search the MCP server index for tools that do email verification? I want to see what's available so I can route my lead validation workflow to the best one.”
Locating on-chain risk analysis tools
“Search the agent tool directory for MCP servers that handle on-chain risk or crypto wallet analysis — show me what's indexed with their compressed descriptions.”

Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP server or A2A tool is best suited for a specific capability without connecting to each one individually. It is especially useful when building multi-agent swarms that need dynamic tool selection, or when you want a firewall-filtered, token-efficient index search rather than manually curating MCP registries.
Side effects
- Empty or too-vague query returns no matches or overly broad results
- Queried capability not yet indexed returns empty result set
- Rate limiting or payment failure (x402) blocks the request
- Endpoint URL verification query returns compliance failure if target is down
- Token compression may strip nuanced endpoint metadata in edge cases
