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/tool-search)
Output
Returns a ranked list of matching MCP servers and A2A tools from a meta-index of 500+ entries, including tool names, descriptions, capabilities, and connection details, with token-compressed output for efficient agent consumption.
Example use cases
Discovering web browsing tools for agents
“Search the AgentDiet tool index for any MCP servers or A2A tools that can help my agent browse and scrape web pages — query for 'web browsing scraping' and list what comes back.”
Finding payment-capable agent tools
“I need my AI agent to be able to execute crypto payments — can you search the AgentDiet tool directory for MCP or A2A tools related to 'crypto payment execution' and tell me what's available?”
Locating document summarization tools
“My agent needs a tool for summarizing long documents — search AgentDiet's index of 500+ tools for anything matching 'document summarization' and return the top results.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability, rather than hard-coding tool references. Ideal for agent orchestration systems that need to route tasks to the best available tool at runtime. Prefer over manual curation when the tool landscape changes frequently or when covering 500+ potential integrations.
Side effects
- Empty query string returns no results or validation error
- Query too vague returns irrelevant or low-confidence matches
- Service unavailable if meta-index is being updated
- Payment not processed results in 402 error blocking access
- Rate limiting if too many calls made in short succession
