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 agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning compressed tool descriptors through a prompt-injection firewall proxy

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://agentdiet.dev/v1/crypto-alpha-dag)
Output
Returns a structured object containing matched MCP server and A2A tool descriptors relevant to the query, with up to 85% token compression applied to reduce prompt overhead, and all results filtered through the Prompt-Guard firewall to block hidden injection attacks.
Example use cases
Agent swarm tool bootstrapping
“I'm spinning up a new agent swarm and need to find all available MCP tools that handle 'SEC filings and company enrichment' — can you query the meta-router and give me the top matches with their capabilities?”
Safe proxied capability search
“Before my agent calls any external tool, I want to find MCP servers that do 'web distillation and content summarization' and have them routed through the prompt-guard firewall — search the tool index for me.”
Capability gap discovery for pipeline
“My agent pipeline needs a tool for 'on-chain risk scoring' — search the 500+ indexed MCP servers and A2A tools for the best match and return a token-compressed summary I can feed directly into my prompt.”
Technical details
Endpoint
POSThttps://agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without hardcoding tool lists. Ideal for agent swarms that need single-connection access to a broad tool ecosystem with built-in prompt-injection safety and token budget constraints. Prefer over manual tool registries when you need compressed, firewall-sanitized tool metadata at runtime.
Side effects
- Query too vague returns low-relevance tool matches
- No matching tools found for niche capability query returns empty result set
- Prompt-Guard firewall blocks query if it resembles injection pattern
- Malformed query string (empty or null) returns 400 validation error
- Payment not fulfilled via x402 returns 402 Payment Required
- Timeout if downstream MCP index is slow to respond
