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://token-intel.agentdiet.dev/api/mcp/audit)
Output
Returns a compressed, firewall-filtered list of matching MCP servers and A2A tools from a 500+ entry index, including capability descriptions and routing metadata, with approximately 85% token reduction compared to raw tool listings.
Example use cases
Discovering tools for GitHub security audits
“Find me MCP servers or A2A tools in the index that can do GitHub security scanning — I want to pick the best one to plug into my pipeline.”
Routing agent to context compression capability
“Search for tools that do context compression so I can cut down on token usage in my agent swarm — show me what's available in the index.”
Verifying a specific MCP endpoint before use
“Can you check whether this endpoint URL is listed in the MCP tool index and tell me what capabilities it offers: https://some-mcp-server.example.com/api/tools”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool supports a given capability without hardcoding integrations, or when you want a single-connection proxy to 500+ tools with built-in token compression and prompt injection protection. Prefer it over direct MCP server registries when token budget is tight or when safety filtering of tool responses is required.
Side effects
- Empty query string returns validation error (query is required, minLength 1)
- Query matches no indexed tools — returns empty result set
- Upstream MCP index unavailable — may return 503 or timeout
- Payment not fulfilled — returns HTTP 402 requiring x402 Base USDC payment
- Prompt-Guard firewall blocks query flagged as potentially malicious — returns rejection with firewall reason
