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
Returns a structured object containing matched MCP servers or A2A tool listings relevant to the search query, with metadata such as endpoint URLs, capability summaries, and token-compressed context. May also include Prompt-Guard firewall validation results if routing through a proxied tool.
Example use cases
Agent pipeline tool discovery
“I'm building an autonomous agent and need to find which indexed MCP servers can handle SEC filings or financial intelligence — search the tool index for me and give me the best matches.”
Safe proxy routing for untrusted tools
“I want to route my agent's request through a prompt-guard firewall before it hits an external MCP server — search for 'github security audit' in the tool index and proxy the call safely.”
Token-compressed multi-tool context lookup
“My agent is running low on context budget — search the MCP index for 'context compression' tools and return the most relevant ones with 85% token reduction applied.”
Technical details
Endpoint
POSThttps://whale-momentum.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover the right MCP server or A2A tool among a large indexed catalog without maintaining separate connections to hundreds of endpoints. Ideal when token budget is constrained (85% compression), when prompt injection protection is required before routing to external tools, or when building swarm architectures that need dynamic tool selection at runtime.
Side effects
- Empty or vague query returns no meaningful matches
- Query targets a capability not yet indexed among the 500+ servers
- Prompt-Guard firewall blocks a legitimate query flagged as suspicious
- Payment not processed via x402, resulting in 402 response with no data
- Upstream MCP server is offline, causing proxy routing failure
- Idempotency-Key collision causes unexpected cached response reuse
