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://serp-extract.agentdiet.dev/v1/mcp-router)
Output
Returns a compressed, token-pruned list of matching MCP servers or A2A tools from a 500+ endpoint index, including their metadata, routing instructions, and safety status as determined by the Prompt-Guard firewall layer.
Example use cases
Finding a tool for B2B lead enrichment
“Search the MCP router for any available agent tools that do B2B company enrichment or contact extraction — I want to know which servers in the index support that capability.”
Routing swarm agents to the right tool
“I'm building a multi-agent swarm and need to discover which MCP servers in your index can handle on-chain risk analysis or DEX token intelligence — can you find and route me to the best match?”
Verifying a known endpoint before use
“Check whether this endpoint URL is listed and verified in your MCP tool index: https://serp-extract.agentdiet.dev/v1/sec-filings — I want to confirm it's safe and get its metadata before my agent calls it.”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding tool URLs. It is especially useful in swarm architectures, orchestration layers, or meta-agents that need to route subtasks to appropriate specialized tools. Prefer this over manual tool registries when breadth of coverage (500+ indexed servers), token compression, and a safety firewall are priorities.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or niche queries
- Endpoint URL verification returns unrecognized/unlisted result
- Upstream MCP server index temporarily unavailable causing partial results
- Rate limit or payment failure via x402 preventing access
