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://whale-momentum.agentdiet.dev/api/mcp/audit)
Output
Returns a list of matching MCP servers or A2A tools from a 500+ item index, including tool names, capabilities, endpoint URLs, and token-compressed descriptions, filtered through a Prompt-Guard firewall for safety
Example use cases
Finding a GitHub security audit tool
“I need to find an MCP server or A2A tool that can audit GitHub repositories for security issues — search the tool index for 'github security' and tell me what's available.”
Discovering SEC filing data tools
“Which MCP servers in your index can handle SEC EDGAR filings or 10-K data? Search for 'sec filings' and give me the best matching tools.”
Routing agent to context compression capability
“My agent needs to compress large context windows before sending them — search the tool index for 'context compression' and find me a suitable MCP endpoint I can route to.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool handles a given capability at runtime, rather than hardcoding tool URLs. Especially useful when building swarm architectures or meta-agents that need to route sub-tasks to specialized tools across a large, curated index.
Side effects
- Missing or empty query parameter returns validation error
- No matching tools found for obscure capability queries
- Firewall may block or sanitize queries containing prompt injection patterns
- Endpoint may return generic object response with unclear structure
- Payment required (HTTP 402) if x402 balance is insufficient
