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/swarm-execute)
Output
Returns a compressed manifest of matching MCP servers or A2A tools relevant to the query, including tool names, descriptions, and routing metadata, filtered through a Prompt-Guard firewall to remove malicious content. Response is token-compressed by up to 85%.
Example use cases
Discover tools for GitHub security audits
“Search the swarm router for MCP tools that can do GitHub security audits — I want to know what's available and what each tool does.”
Find prompt-safe proxy for domain OSINT
“I need to route a domain OSINT query through a safe proxy — search the meta-router for tools that handle domain intelligence and give me the best match.”
Locate context compression MCP servers
“Which MCP servers in your index support context compression? Search for 'context compression' and list what you find with any relevant details.”

Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without maintaining its own tool registry. Especially useful when you want a single connection point that applies prompt-guard safety filtering and token compression before returning tool metadata, reducing both security risk and context overhead compared to querying multiple registries directly.
Side effects
- Empty query string returns validation error
- No matching tools found for niche query returns empty result set
- Rate limiting or payment failure (HTTP 402) if per-call credit is exhausted
- Upstream MCP server index unavailable returns 503
- Malformed endpoint URL passed as query may return unverified or null routing result
