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://whale-momentum.agentdiet.dev/v1/b2b-osint-dag)
Output
A compressed list of matching MCP server or A2A tool descriptors relevant to the capability query, including endpoint metadata, with 85% token compression applied and prompt-guard firewall filtering applied to remove unsafe or malicious entries.
Example use cases
Discover GitHub security audit tools
“I need to find an MCP server or A2A tool that can do GitHub security audits — search the tool index for 'github security' and show me what's available.”
Route swarm to domain OSINT capability
“Can you search the agent tool directory for 'domain OSINT' and tell me which MCP endpoints I should route my swarm to for that capability?”
Find email verification endpoint
“Look up 'email verification' in the MCP tool index and give me the best matching endpoints I can plug into my agent pipeline.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or swarm needs to dynamically discover which MCP servers or A2A tools support a given capability at runtime, especially when the agent does not have a hardcoded tool registry and needs to search across 500+ indexed providers. Prefer this over direct MCP connections when token budget is constrained (85% compression) or when prompt injection safety is required.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability queries
- Prompt-guard firewall may block queries flagged as potentially harmful
- Rate-limiting or payment failure (HTTP 402) if x402 credentials are missing or insufficient
- Upstream MCP server index may be stale or temporarily unavailable
