The nerlo CLI
The command-line client for the Nerlo registry: search scanned MCP servers, read their scoresheets, install verified skills, and submit new repositories for scanning.
Install
pip install nerlo
nerlo --help
Consumer commands
Search the registry
Keyword search across name, description, and author (2–100 characters):
nerlo search "weather"
nerlo search "weather" --json
Inspect a server
Score, badge, and the full per-scanner scoresheets for a skill:
nerlo info weather-mcp
The output mirrors the registry website: every scanner's verdict is shown, and the composite is labelled as one view among many.
Install a skill
Writes an mcpServers config entry for your platform. Runnable directly for
npm/PyPI-hosted packages; other sources get a repository reference you finish
wiring manually. Requires an API token:
nerlo install weather-mcp --target claude-code
Install respects the composite badge — Verified proceeds, Caution prompts for confirmation, Unsafe is refused.
Publisher commands
Submit a repository
Queue a repository for ingestion and scanning (authenticated):
nerlo submit https://github.com/you/your-mcp-server --token $NERLO_API_TOKEN
Request a re-scan
By server UUID or skill slug (authenticated):
nerlo rescan weather-mcp --token $NERLO_API_TOKEN
Tokens
Authenticated commands read --token or the NERLO_API_TOKEN environment
variable. Tokens are issued per account; treat them like passwords.
Configuration
Point the CLI at a different registry with --api-url or NERLO_API_BASE_URL
(defaults to https://api.nerlo.ai).
