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/code-release-security-gate)
Output
A list of matching MCP server or A2A tool entries relevant to the query, with compressed capability descriptions (up to 85% token reduction) and Prompt-Guard firewall filtering applied. Results include tool names, capability summaries, and connection details.
Example use cases
Discovering context compression tools
“Search the MCP index for tools that support context compression — I want to find what's available through a single connection with token savings.”
Finding GitHub security audit agents
“Can you look up which MCP servers or A2A tools handle GitHub security audits? I need a safe-proxied option I can route through.”
Locating B2B lead enrichment tools
“Search the agent tool index for anything that does company enrichment or B2B lead enrichment — show me the top results with capability summaries.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/workflows/code-release-security-gate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover which of 500+ MCP servers or A2A tools supports a specific capability, and wants results delivered through a single safe-proxied connection with token-compressed output and prompt injection protection — rather than managing direct connections to many individual servers.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability queries
- Endpoint URL verification returns inconclusive result if the target is offline
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not properly included
