Cursor config for AWS MCP Server

uvx aws-mcp
{
  "mcpServers": {
    "aws-mcp-server": {
      "command": "uvx",
      "args": [
        "aws-mcp"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Setup steps

  1. 1Open Cursor → Settings → MCP → Add new MCP server (or edit ~/.cursor/mcp.json directly).
  2. 2Paste the AWS MCP Server config below into the "mcpServers" object.
  3. 3Fill in placeholder secrets, then save.
  4. 4Cursor reloads MCP servers automatically — check Settings → MCP for a green status dot.
  5. 5Ask Cursor to use one of AWS MCP Server's tools to confirm it's connected.

Before you start

  • AWS CLI installed
  • AWS credentials configured (env vars, ~/.aws/credentials, ~/.aws/config, or IAM role)
  • uv installed (for uvx), or Docker

aws_cli_pipeline

Execute AWS CLI commands with optional pipes (jq, grep, etc.).

Security

Your IAM policy is your security boundary — the server executes whatever AWS commands Claude requests, and IAM controls what actually succeeds. Use a least-privilege IAM role, never use root credentials, and consider running via Docker for additional host isolation. A sandbox mode (AWS_MCP_SANDBOX) is available.

AWS MCP Server + Cursor FAQ

Where is the Cursor config file?

Cursor reads MCP servers from ~/.cursor/mcp.json. Paste the AWS MCP Server config there under the "mcpServers" key and restart the client.

Is AWS MCP Server safe to use with Cursor?

Your IAM policy is your security boundary — the server executes whatever AWS commands Claude requests, and IAM controls what actually succeeds. Use a least-privilege IAM role, never use root credentials, and consider running via Docker for additional host isolation. A sandbox mode (AWS_MCP_SANDBOX) is available.

How does it control what AWS actions Claude can take?

Your IAM policy is the security boundary. The server executes whatever AWS commands Claude requests, but IAM controls what actually succeeds. Use a least-privilege role and never use root credentials.

Which transports are supported?

stdio (default), streamable-http for web-based MCP clients, and a deprecated sse transport. Set the transport via the AWS_MCP_TRANSPORT environment variable.

How are AWS credentials provided?

Via the standard AWS credential chain: environment variables, ~/.aws/credentials, ~/.aws/config (profiles and region), or an IAM role when running on EC2, ECS, or Lambda. Set AWS_PROFILE to use a specific profile.
