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/execute)
Output
Returns a compressed list of matching MCP servers and A2A tools relevant to the query, including tool names, capabilities, and routing metadata — delivered with up to 85% token compression compared to raw tool schemas. May also verify whether a provided endpoint URL is a valid, compliant MCP/A2A endpoint.
Example use cases
Agent tool discovery for GitHub audits
“Search your MCP index for any tools that can do GitHub security audits or code scanning — I want to know what's available before I build my next agent pipeline.”
Finding lead enrichment tools
“I need to enrich B2B leads with company data — can you search the A2A and MCP tool registry for anything that does company or contact enrichment and tell me which ones are available?”
Routing to context compression tool
“Look up 'context compression' in the MCP tool index and route me to the best server that can help my agent reduce token usage in long conversations.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to delegate a subtask to, rather than hard-coding tool integrations. Ideal for meta-agents or swarm orchestrators that need to find the right capability at runtime across a broad index of 500+ tools. Prefer this over manual tool registries when you need prompt-injection protection (Prompt-Guard firewall) and compressed tool metadata to stay within context limits.
Side effects
- Empty or too-vague query returns low-relevance or no results
- Queried endpoint URL is unreachable or not a valid MCP/A2A endpoint
- Index may not include newly launched MCP servers not yet crawled
- Token compression artifacts may occasionally omit edge-case schema details
- Rate limiting or payment failure (x402) blocks the request
