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/mesh)
Output
Returns a paginated list of matching MCP server or A2A tool entries with endpoint metadata such as capability descriptions, URLs, and relevance scores, plus an opaque cursor for fetching additional pages. The response is compressed for token efficiency.
Example use cases
Find context compression tools for agent
“Search the MCP tool directory for anything related to 'context compression' — I want to see which agent endpoints can help reduce token usage, show me up to 20 results.”
Discover web scraping A2A agents
“Can you look up available MCP servers and A2A tools that handle web scraping or URL distillation? Fetch the top 10 results from the mesh index.”
Route swarm to GitHub security auditors
“Search the A2A and MCP tool mesh for 'github security audit' capabilities — I want to find agent endpoints my swarm can delegate code review tasks to, up to 15 results please.”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/mesh?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or swarm needs to dynamically discover which MCP servers or A2A tools support a given capability at runtime, rather than relying on a hardcoded list. Prefer it over manual directory lookups when you need token-compressed results and a prompt-guard firewall on returned tool descriptions.
Side effects
- Empty query string returns a validation error requiring minLength of 1
- No matching tools found returns an empty results array
- Cursor invalid or expired returns a pagination error
- Rate limiting or payment failure (HTTP 402) blocks the request
- Upstream MCP server index unavailable returns a service error
