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://json-repair.agentdiet.dev/v1/tool-broker)
Output
Returns a compressed, Prompt-Guard-screened list of matching MCP servers or A2A tools from the meta-index, with up to 85% token reduction compared to raw tool manifests. Includes tool names, capability descriptions, and routing metadata relevant to the query.
Example use cases
Swarm agent capability discovery
“Find me all available MCP tools that support context compression and token reduction — I'm building a swarm and need to know what's indexed in the tool broker.”
Vetting a specific endpoint URL
“Can you check the tool broker to verify whether this endpoint URL is listed and safe to proxy: https://example-tool.dev/v1/analyze?”
Routing agent to SEC filings tool
“My agent needs to pull SEC filings data — search the tool broker for any indexed MCP servers or A2A tools that cover that capability and return the best match.”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover, search, or route to external MCP servers or A2A tools without maintaining its own registry. Ideal for swarm orchestration scenarios where a single-connection meta-router with built-in firewall protection and token compression is preferred over manually curating tool lists.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries returns empty result set
- Endpoint URL verification may return unverified status if URL is not indexed
- Rate limiting or payment failure (x402) may block access
- Prompt-Guard firewall may reject queries containing adversarial or injection-like patterns
