Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches and routes queries across 500+ indexed MCP servers and A2A tools through a single meta-router endpoint with token compression and prompt-injection firewall

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/v1/workflows/execute)
Output
Returns a list of matching MCP servers or A2A tool endpoints relevant to the search query, with compressed capability descriptions, tool metadata, and routing information. Results are filtered through a Prompt-Guard firewall to prevent prompt-injection attacks from upstream tools.
Example use cases
Discover tools for GitHub security audits
“Look through the MCP tool registry and find me any servers or A2A agents that can do GitHub security audits or code vulnerability scanning.”
Find email verification MCP endpoint
“Search the tool index for email verification capabilities — I need to find an MCP server that can validate whether a list of email addresses are real.”
Route to on-chain risk analysis tool
“I need to analyze on-chain risk for a DeFi wallet — can you search the available MCP tools and find the right one to route this through?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool is best suited for a given capability without hardcoding individual tool URLs. Prefer this over direct MCP connections when you want a single normalized interface across 500+ tools, need token-compressed manifests to reduce context usage, or require a security firewall layer to protect against prompt-injection from untrusted tool descriptions.
Side effects
- Empty query returns validation error
- No matching tools found for obscure capability queries
- Upstream MCP server unavailable causing partial results
- Token compression may truncate detailed schema information
- Payment required (HTTP 402) if USDC balance insufficient
