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://alpha-stream.agentdiet.dev/v1/crypto-alpha-dag)
Output
Returns a list of matched MCP servers or A2A tools relevant to the capability query, with compressed metadata (85% token reduction) and Prompt-Guard firewall filtering applied. Results include tool names, descriptions, endpoint URLs, and routing metadata.
Example use cases
Discover crypto data MCP tools
“Search the MCP tool index for anything related to crypto price feeds or on-chain DEX token intelligence — I want to find available endpoints my agent can call.”
Find a GitHub security auditing agent
“Look up available A2A or MCP tools in the index that do GitHub security audits or code vulnerability scanning — what's indexed and ready to proxy?”
Route agent to company enrichment tool
“Find me the best available MCP server or A2A tool for B2B lead enrichment and company data — search the index for 'company enrichment' and tell me what comes back.”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability rather than hardcoding endpoint URLs. Prefer it when building multi-agent orchestration systems that need to route to the best available tool at runtime, especially when token efficiency matters.
Side effects
- Empty results if the query is too specific or no indexed tools match
- Rate limiting or payment required (HTTP 402) if request quota is exceeded
- Malformed query string returns validation error
- Timeout if the meta-router index is temporarily unavailable
- Prompt-Guard firewall may block queries flagged as adversarial
