How this service works
ShieldAPI - MCP Server Trust Score
Output
Returns a trust score and risk assessment for the specified MCP server endpoint, indicating whether it is safe for an AI agent to connect to or invoke, along with supporting evidence or signals used to compute the score.
Example use cases
Vetting unknown MCP tool servers
“I found an MCP server at https://someplugin.io/mcp that claims to handle payments — can you check its trust score before I let it handle anything?”
Pre-connection safety check in agent workflow
“Before my agent routes any requests through https://mcptools.example.dev/api, run a ShieldAPI trust score check on it so I know if it's safe to use.”
Auditing third-party AI integrations
“We're evaluating a third-party MCP server at https://partner-tools.acme.com/mcp for our agent pipeline — can you get a trust score on it before we approve the integration?”
Technical details
Endpoint
POSThttps://shield.vainplex.dev/api/cdp/check-mcp-trustWhen to prefer
Use this endpoint specifically when an AI agent needs to evaluate whether an MCP (Model Context Protocol) server is trustworthy before connecting to it, installing it, or routing tool calls through it. This is the right choice when the subject being checked is an MCP server URL — as opposed to general domain trust, IP reputation, identity checks, or dependency scanning, which are covered by sibling ShieldAPI endpoints.
Side effects
- Invalid or unreachable MCP server URL returns an error or low-confidence score
- Malformed input missing required 'endpoint' query parameter triggers validation error
- Unknown or newly registered MCP server may return low trust score due to lack of signal
- Network timeout if the MCP server endpoint is unresponsive during analysis
- Payment failure (x402) if USDC balance is insufficient for the $0.02 per-call fee
