Install

The sweep installs into a clean prefix, but this is the command a user would run:

npx onepassword-mcp-server

Needs credentials: OP_SERVICE_ACCOUNT_TOKEN. The probe used placeholder values, so an amber needs credentials result below means the server asked for the real ones, not that it is broken. Maintainers: how to go green.

handshake failed: MCP error -32000: Connection closed
--- stderr (tail) ---
[ERROR] security: Server cannot start: no elicitation mechanism is configured.

This 1Password MCP server requires user confirmation prompts (elicitation) to be
configured before it will start. Without elicitation, all secrets would be accessible
to any connected MCP client without user approval.

To fix this, choose one of the following options:

  Option 1: Configure HTTP elicitation fallback (recommended):
    export ELICITATION_REQUEST_URL="https://your-endpoint/request"
    export ELICITATION_POLL_URL="https://your-endpoint/poll"

  Option 2: Explicitly opt out of elicitation (use with caution):
    export DANGEROUSLY_SKIP_ELICITATIONS=true

Note: If your MCP client supports native elicitation (e.g., Claude Desktop),
you still need to configure HTTP fallback URLs or set DANGEROUSLY_SKIP_ELICITATIONS=true
since native support cannot be verified at server startup time.
