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/workflows/execute)
Output
Returns a structured list of matched MCP servers or A2A tools from the 500+ index, including endpoint metadata, capability descriptions, and routing information. Responses are compressed by up to 85% in token count and passed through a Prompt-Guard firewall to prevent prompt injection.
Example use cases
Discover context compression tools
“Search across all indexed MCP servers and find me any tools or agents that specialize in context compression or token reduction for AI pipelines.”
Find GitHub security audit agents
“I need to find an MCP server or A2A agent in the index that can audit GitHub repos for security and license risks — can you search the tool directory for that capability?”
Route to on-chain risk tool
“Search the meta-router index for any available tools that cover on-chain risk analysis or DEX token intelligence so I can plug the right one into my swarm.”
Technical details
Endpoint
POSThttps://json-repair.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. It is especially valuable in multi-agent swarm architectures where the right downstream tool is not known in advance, or when you want a safe-proxied, token-efficient single connection to a broad ecosystem of 500+ tools.
Side effects
- Empty or overly vague query returns no useful matches
- Queried capability not yet indexed returns empty result set
- Endpoint URL verification fails if target is offline or non-compliant
- Rate limiting or payment failure (x402) may block execution
- Prompt-Guard firewall may reject queries that resemble injection attempts
