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://mcp-compiler.agentdiet.dev/v1/workflows/execute)
Output
A compressed list of matching MCP servers or A2A tools relevant to the query, including endpoint metadata, capability summaries (with up to 85% token reduction), and Prompt-Guard firewall screening status, all accessible through a single proxied connection.
Example use cases
Finding the right SEC data tool
“I need to find an MCP server that can pull SEC filings for a given company — search the tool index for 'SEC filings' and tell me which servers are available and what they offer.”
Routing agent to GitHub security tools
“My agent needs to run a GitHub security audit. Can you search the MCP router for tools that handle GitHub security scanning and return the top options?”
Discovering email verification endpoints
“I'm building a lead validation workflow and need an MCP or A2A endpoint for email verification — search the index and show me what's available with their descriptions.”
Technical details
Endpoint
GEThttps://mcp-compiler.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 handles a specific capability without maintaining dozens of individual connections, or when you want token-compressed tool descriptions with built-in prompt injection firewall protection. Prefer it over manually curating a list of MCP endpoints, especially for agentic workflows that need dynamic tool routing across a large, heterogeneous tool ecosystem.
Side effects
- No matching tools found for the query — returns empty result set
- Query too vague to disambiguate tool categories — returns mixed or low-confidence matches
- Upstream MCP server unavailable — proxy reports connectivity failure for that server
- Rate limit or payment failure via x402 — 402 Payment Required response
- Query string missing or empty — validation error returned
