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://polymarket-odds.agentdiet.dev/v1/crypto-alpha-dag)
Output
Returns a list of matching MCP servers or A2A tools relevant to the capability query, with token-compressed descriptions (up to 85% compression), safety-filtered through a Prompt-Guard firewall, and optionally a verification result if an endpoint URL was provided.
Example use cases
Discovering GitHub security audit tools
“Can you search the MCP tool index for anything that does GitHub security audits or code vulnerability scanning? I want to know what agents or servers are available for that.”
Finding on-chain DeFi risk tools
“Look up what MCP servers or A2A tools are available for on-chain risk analysis and DEX token intelligence — I need something I can route crypto alpha queries through.”
Verifying a specific MCP endpoint
“Can you verify whether this endpoint URL is a valid MCP server and check if it's compliant: https://some-agent.example.com/mcp”
Technical details
Endpoint
GEThttps://polymarket-odds.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 exist for a given capability, rather than hardcoding a specific tool. Especially useful when building swarm orchestrators or agent pipelines that need to route tasks to the best available tool at runtime. Prefer this over manual tool registries when you need token-efficient results across a large catalog of 500+ servers.
Side effects
- Empty or too-broad query returns low-relevance results
- Queried endpoint URL is unreachable or non-compliant, returning an error or failed verification
- Index may not include newly registered MCP servers if not yet indexed
- Prompt injection attempts in query are blocked by firewall and may return a rejection response
- Payment not completed (HTTP 402) blocks access to results
