add_drop_rule
Adds a new drop rule to filter out specific logs at Last9 Control Plane
Parameters:
name(string, required): Name of the drop rule.
filters(array, required): List of filter conditions to apply. Each filter has:
Installation
You can install the Last9 Observability MCP server using either:
Homebrew
NPM
Configuration
Environment Variables
The service requires the following environment variables:
LAST9_AUTH_TOKEN: Authentication token for Last9 MCP server (required)
LAST9_BASE_URL: Last9 API URL (required)
LAST9_REFRESH_TOKEN: Refresh Token with Write permissions. Needed for accessing control plane APIs (required).
- Signup at Last9 and setup one of the integrations.
- Obtain
LAST9_BASE_URLandLAST9_AUTH_TOKENfrom here.
- The Write Refresh Token can be obtained from API Access page.
Usage with Claude Desktop

- Go to Settings, then Developer, click Edit Config
- Open the
claude_desktop_config.jsonfile
- Copy and paste the server config to your existing file, then save
- Restart Claude
Usage with Cursor
Configure Cursor to use the MCP server:
- Navigate to Settings, then Cursor Settings
- Select MCP on the left
- Click Add new global MCP server at the top right
- Copy and paste the server config to your existing file, then save
- Restart Cursor
Usage with Windsurf
