Add this to .mcp.json in your project root (or ~/.claude.json for a user-scoped install):

{
  "mcpServers": {
    "plaid": {
      "command": "uvx",
      "args": [
        "mcp-server-plaid",
        "--client-id",
        "YOUR_PLAID_CLIENT_ID",
        "--secret",
        "YOUR_PLAID_SECRET"
      ]
    }
  }
}

Or use the CLI:

claude mcp add plaid -- uvx mcp-server-plaid --client-id YOUR_PLAID_CLIENT_ID --secret YOUR_PLAID_SECRET

For quick installation, use the one-click installation button.

For manual installation, add the following JSON block to Cursor MCP config file.

{
  "mcpServers": {
    "plaid": {
      "command": "uvx",
      "args": [
        "mcp-server-plaid",
        "--client-id",
        "YOUR_PLAID_CLIENT_ID",
        "--secret",
        "YOUR_PLAID_SECRET"
      ]
    }
  }
}

Add this to ~/.codex/config.toml:

[mcp_servers.plaid]
command = "uvx"
args = ["mcp-server-plaid", "--client-id", "YOUR_PLAID_CLIENT_ID", "--secret", "YOUR_PLAID_SECRET"]

For quick installation, use one of the one-click installation buttons below.

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is needed when using the mcp.json file.

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "client_id",
        "description": "Plaid Client ID",
        "password": false
      },
      {
        "type": "promptString",
        "id": "secret",
        "description": "Plaid Secret",
        "password": true
      }
    ],
    "servers": {
      "plaid": {
        "command": "uvx",
        "args": ["mcp-server-plaid"],
        "env": {
          "PLAID_CLIENT_ID": "${input:client_id}",
          "PLAID_SECRET": "${input:secret}"
        }
      }
    }
  }
}

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "plaid": {
      "command": "uvx",
      "args": [
        "mcp-server-plaid",
        "--client-id",
        "YOUR_PLAID_CLIENT_ID",
        "--secret",
        "YOUR_PLAID_SECRET"
      ]
    }
  }
}

Add to your Zed settings.json:

{
   "context_servers": {
      "mcp-server-plaid": {
         "command": {
            "path": "uvx",
            "args": [
               "mcp-server-plaid",
               "--client-id",
               "YOUR_PLAID_CLIENT_ID",
               "--secret",
               "YOUR_PLAID_SECRET"
            ]
         }
      }
   }
}

You can use the MCP inspector to debug the server. For uvx installations:

npx @modelcontextprotocol/inspector uvx mcp-server-plaid --client-id YOUR_PLAID_CLIENT_ID --secret YOUR_PLAID_SECRET

Or if you've installed the package in a specific directory or are developing on it:

cd path/to/servers/src/plaid
npx @modelcontextprotocol/inspector uv run mcp-server-plaid --client-id YOUR_PLAID_CLIENT_ID --secret YOUR_PLAID_SECRET
