How this service works
ShieldAPI - MCP Server Trust Score
Output
Returns a trust score and supporting assessment for the given MCP server endpoint URL, indicating how safe or reputable the server is for an AI agent to connect to and use.
Example use cases
Preflight before installing new MCP tool
“I want to add a new MCP server at https://data-tools.somevendor.io/mcp to my agent setup — can you check its trust score first and tell me if it looks safe?”
Verify community-shared MCP endpoint
“Someone shared this MCP server URL with me: https://community-mcp.example.net/api — what's its trust score? I don't want to connect my agent to something sketchy.”
Automated agent safety gating
“Before my agent calls any new MCP server it discovers, I want it to check the trust score of that server's endpoint and only proceed if the score is acceptable — run the trust check on https://unknown-mcp.dev/server now.”
Technical details
Endpoint
POSThttps://shield.vainplex.dev/api/cdp/check/mcp/trustWhen to prefer
Use this endpoint specifically when you need to evaluate the trustworthiness of an MCP (Model Context Protocol) server before an AI agent connects to or executes tools from it. Prefer this over generic domain or URL trust checks when the target is explicitly an MCP server endpoint, as the scoring is tailored to MCP server signals and agentic risk factors.
Side effects
- Invalid or unreachable endpoint URL returns an error or low trust score
- Malformed input schema (missing required 'type' or 'method' fields) results in a 400-level error
- Unknown or brand-new MCP servers may have insufficient data for a reliable score
- Payment failure (x402) if USDC balance is insufficient
- Network timeout if the target MCP server URL is slow to probe
