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://domain-osint.agentdiet.dev/v1/mcp-gateway)
Output
A paginated JSON object listing matching MCP servers and A2A tools, including endpoint metadata, capability descriptions, and relevance-ranked results, compressed with up to 85% token reduction. Includes an opaque cursor for fetching additional pages.
Example use cases
Discovering tools for SEC financial data
“Search the MCP gateway for any tools or servers that handle SEC filings or 10-K financial intelligence — show me up to 20 results so I can pick one to wire into my research agent.”
Finding prompt injection firewall tools
“I need to protect my agent swarm from indirect prompt injection — search the MCP tool index for 'prompt firewall' or 'jailbreak detection' tools and list what's available.”
Locating token compression MCP servers
“My agent is hitting context limits — search the MCP gateway index for servers that offer context compression or token pruning capabilities, give me the top 15 matches.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover MCP-compatible or A2A-compatible tools at runtime without pre-configuring dozens of individual connections. Ideal for swarm orchestrators, agent pipelines, or meta-agents that need to find the right capability on demand. Preferable over hard-coding individual MCP server URLs when the tool landscape is evolving or unknown.
Side effects
- Empty query string returns validation error
- Query matching no indexed tools returns empty results list
- Cursor from a previous session may be stale and return 404 or empty page
- Rate limiting or payment failure (x402) if micropayment not resolved
- Limit value out of range (>100 or <1) returns 400 bad request
