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://serp-extract.agentdiet.dev/v1/agent-tool-marketplace)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with token-compressed descriptions, relevance scores, and routing metadata. The response includes tool capabilities, connection details, and safety/firewall status for each matched tool.
Example use cases
Finding tools for SEC filings research
“Search the agent tool marketplace for any MCP servers or A2A tools that can pull SEC filings — I need to build an agent that monitors company disclosures.”
Discovering GitHub security audit tools
“Can you search the agent marketplace for tools that do GitHub security audits? I want to add one to my swarm that reviews repos for vulnerabilities.”
Routing to company enrichment capabilities
“Look up what tools are available for B2B lead enrichment and company data — I want to find the best MCP server I can plug into my sales research agent.”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/agent-tool-marketplace?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover new tools or MCP servers at runtime rather than hardcoding integrations. Ideal for swarm orchestrators that need to find the best available tool for a given capability, or when you want a single connection point that abstracts away routing to 500+ servers with built-in prompt-injection protection and token compression.
Side effects
- Empty or vague query returns no matches or low-relevance results
- Queried capability not indexed among the 500+ servers returns empty set
- Prompt-Guard firewall may block queries containing injection-like patterns
- Payment required (HTTP 402) if x402 credits are exhausted
- Malformed query (minLength not met) returns validation error
- Timeout if upstream MCP server probing is slow
