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://workflows.agentdiet.dev/v1/workflows/code-release-security-gate)
Output
Returns a list of matching MCP servers and A2A tool endpoints relevant to the capability query, with 85% token-compressed metadata and firewall screening applied. May include endpoint URLs, capability descriptions, latency indicators, and safety flags.
Example use cases
Finding SEC filing tools for a research agent
“I need to find all MCP servers or A2A tools that can pull SEC filings or financial disclosures — can you search the tool index and show me what's available?”
Routing swarm queries through a safe proxy
“My agent swarm needs a safe, compressed connection to discover and call MCP tools for GitHub security audits — search for 'github security' in the tool registry and route me to the best match.”
Verifying an unknown MCP endpoint URL
“I have this MCP endpoint URL I found and I'm not sure if it's legitimate — can you check it against the tool index and verify whether it's a known, safe endpoint?”
Technical details
Endpoint
GEThttps://workflows.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 MCP servers or A2A tools support a given capability without maintaining its own registry, or when safe proxying and token compression across a large tool ecosystem is required. Prefer over direct MCP registries when prompt-injection protection and unified single-connection routing across 500+ servers matters.
Side effects
- Empty query string returns validation error
- Unknown or unindexed endpoint URL returns no match
- Prompt injection attempts blocked by Prompt-Guard firewall with rejection notice
- Service unavailable if 500+ server index is unreachable
- Payment not completed (x402) results in 402 response before results are returned
