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/crypto-alpha-dag)
Output
Returns a ranked list of matching MCP servers or A2A tool endpoints with token-compressed metadata, capability descriptions, and routing recommendations filtered through the Prompt-Guard firewall
Example use cases
Discovering crypto risk analysis tools
“Find me all MCP servers in your index that handle on-chain crypto risk or DEX token intelligence — I want to route my trading agent through the best one.”
Locating email verification endpoints
“Search your tool index for any A2A or MCP endpoints that can verify email addresses — I need to plug one into my lead enrichment pipeline.”
Finding GitHub security audit tools
“Which MCP servers in your directory support GitHub security audits or repository scanning? My agent needs to call one for a code review workflow.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover the right MCP server or A2A tool for a capability at runtime, especially when the specific tool URL is unknown. Prefer it over hardcoded tool lists when building swarm agents or meta-orchestrators that must route across many third-party services. The 85% token compression makes it efficient for LLM context budgets, and the Prompt-Guard firewall makes it safer than direct proxy calls to unknown endpoints.
Side effects
- Empty or too-generic query returns no relevant results
- Query matches no indexed tools — empty result set returned
- Endpoint URL verification fails if target is offline or malformed
- Token compression artifacts may truncate tool descriptions for very long results
- Rate limit or 402 payment required if quota exceeded
