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://prompt-guard.agentdiet.dev/v1/workflows/b2b-lead-enrichment)
Output
A token-compressed list of matching MCP server entries and A2A tool endpoints relevant to the query, including capability metadata such as endpoint URLs, tool names, and routing recommendations, all filtered through the Prompt-Guard firewall for safety.
Example use cases
Discovering lead enrichment tools for a sales agent
“I'm building a sales automation agent — search the MCP tool index for anything that handles B2B lead enrichment or company contact lookup and give me the best matching endpoints.”
Routing swarm agents to SEC filing tools
“My agent swarm needs to pull SEC filings data — can you query the tool discovery router for MCP servers or A2A agents that handle SEC filings and return the top options?”
Finding safe-proxied GitHub audit capabilities
“I need my agent to run a GitHub security audit on a repo — search the indexed tool registry for any MCP servers or A2A tools that cover GitHub audits and return a compressed list of what's available.”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/workflows/b2b-lead-enrichment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which of 500+ MCP servers or A2A tools can handle a given capability, rather than hard-coding a specific tool. Ideal for meta-orchestration, swarm routing, and situations where the right downstream tool is unknown at design time. Prefer over manual tool registries when token efficiency and built-in prompt safety filtering are required.
Side effects
- Empty query string returns validation error
- No matching tools found for niche or misspelled query returns empty result set
- Firewall blocks a query flagged as prompt injection attempt
- Upstream MCP server index temporarily unavailable returns 5xx
- x402 payment failure if USDC balance insufficient for $0.01 per-call fee
