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/a2a-router)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the capability query, with compressed descriptions (up to 85% token reduction) and routing metadata. May include endpoint URLs, capability summaries, and safety-filtered results from the Prompt-Guard firewall.
Example use cases
Discovering SEC filing tools for finance agent
“Find me all MCP servers or A2A tools in your index that can pull SEC filings or financial disclosures — I'm building a finance research agent and need the right capability.”
Routing to GitHub security audit capability
“Search your MCP tool index for anything that handles GitHub security auditing or code vulnerability scanning so my agent can use it without me wiring up each server manually.”
Finding context compression tools for token reduction
“Which of the 500+ indexed MCP tools can do context compression or token reduction? I want my agent to handle long documents more efficiently.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP server or A2A tool is best suited for a given capability without maintaining its own registry or connecting to hundreds of individual servers. Ideal for orchestration layers, swarm routers, or any agent that needs to delegate subtasks to the most appropriate specialized tool. Prefer this over hardcoded tool registries or manual MCP server enumeration.
Side effects
- Missing or empty query parameter returns validation error
- No matching tools found for obscure or overly specific capability queries
- Endpoint URL verification queries may time out if remote server is unreachable
- Prompt-Guard firewall may block queries containing injection-like patterns
- x402 payment failure if USDC balance insufficient
- Rate limiting under high-query swarm scenarios
