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 2026-10-21).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning compressed tool descriptions through a 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://agentdiet.dev/v1/web-rag-shield-dag)
Output
Returns a compressed, firewall-filtered list of matching MCP servers or A2A tools from the 500+ tool index, including tool names, capability summaries (with ~85% token compression applied), and safety status from the Prompt-Guard firewall. May also return verification status if an endpoint URL was queried.
Example use cases
Discover tools for GitHub security audits
“Search the MCP tool index for any servers or A2A tools that can do GitHub security auditing or code scanning — I want to know what's available so I can wire one into my pipeline.”
Verify a third-party MCP endpoint
“Can you check whether this endpoint URL is a valid, indexed MCP server and tell me if it passes the prompt-guard firewall check? The URL is https://example-mcp-provider.com/v1/tool.”
Find token-efficient company enrichment tools
“I need to find MCP tools that do B2B company enrichment but use compressed token output so I don't blow my context window — search the tool index for 'company enrichment' and show me what's indexed.”

Endpoint
GEThttps://agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to dynamically discover which MCP servers or A2A tools exist for a given capability without pre-knowing their URLs, or when you want a single safe proxy point that applies prompt-injection filtering before routing to external tools. Particularly useful in multi-agent swarm architectures where tool availability needs to be resolved at runtime. Prefer over manual tool registries when token budget is a constraint, as the 85% compression is a distinctive advantage.
Side effects
- Query returns no matching tools if the capability term is too niche or misspelled
- Endpoint URL verification may return unverified/unsafe if the target is not indexed
- Generic or ambiguous queries may return a large unfiltered set
- Rate limiting or payment failure (x402) may block access
- Token compression artifacts may reduce fidelity of returned tool descriptions
