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/workflows)
Output
A list of matching MCP servers or A2A tools ranked by relevance to the query, including their endpoint metadata, capability descriptions, and routing details, returned through a single compressed connection.
Example use cases
Discovering MCP tools for SEC filings
“Find me an MCP server that can fetch SEC filings — search the tool index for 'sec filings' and tell me what's available.”
Routing to GitHub security auditing tool
“I need an agent tool that can audit GitHub repos for security issues — can you search the MCP index for 'github security' and route me to the best match?”
Finding email verification capability
“Look up which MCP or A2A tools support email verification in the agentdiet index so I can use one in my workflow.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover and route to the right MCP server or A2A tool without managing hundreds of individual connections, especially when token efficiency matters or when prompt injection protection via the Prompt-Guard firewall is required.
Side effects
- No matching tools found for the given query — returns empty result set
- Invalid or unreachable endpoint URL when used in verification mode — returns compliance error
- Query too vague — low-confidence results with irrelevant tool matches
- Service unavailable if the meta-router index is temporarily down
- Payment failure if x402 micropayment of $0.01 is not completed
