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/b2b-osint-dag)
Output
Returns a filtered, token-compressed list of matching MCP servers or A2A tools relevant to the query, including routing metadata, capability descriptions, and Prompt-Guard firewall verdicts for safe proxying.
Example use cases
Discovering OSINT tools for B2B research
“Search the agent tool index for anything related to 'domain OSINT' or 'B2B lead enrichment' — I want to find which MCP servers or A2A tools can help me research a company.”
Finding GitHub security audit capabilities
“Can you query the MCP discovery index for 'github security' and tell me which agent tools are available to audit a code repository for vulnerabilities?”
Routing to a context compression tool
“Search the tool index for 'context compression' — I need to find an MCP server or A2A tool that can compress my agent's token usage before it hits a large context window.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to delegate a task to, rather than hardcoding a specific tool. Useful for swarm orchestration, capability gap-filling, or when the required tool is unknown at design time. Prefer over manual tool registries when token efficiency and firewall safety are priorities.
Side effects
- Empty query string returns validation error (query minLength:1 required)
- Query too vague returns zero or low-confidence matches
- Index may not include very new or unlisted MCP servers
- Prompt injection attempts blocked by Prompt-Guard firewall returning redacted or rejected results
- HTTP 402 payment required if x402 payment header not included
- Unrecognized endpoint URL passed for verification may return null or error result
