CLI Reference

All CLI commands follow the pattern:

perspicacite [-c config.yml] [-v] <subcommand> [options]

Global flags:

  • -c, --config PATH — path to config.yml (default: config.yml in the current directory)
  • -v, --verbose — enable verbose/debug logging

Structured JSON logs go to stderr; clean output (DOI lists, JSON results, progress summaries) goes to stdout so you can pipe into jq, tee, etc.

serve

Start the web server (UI + REST API + MCP server).

perspicacite -c config.yml serve [--host HOST] [--port PORT] [--reload] [--no-mcp] [--no-ui]
Flag Default Description
--host HOST from config Bind address (e.g., 0.0.0.0 or 127.0.0.1)
--port, -p PORT from config Port number
--reload false Enable auto-reload (development only)
--no-mcp false Disable MCP server
--no-ui false Headless mode (REST API only, no web UI)

create-kb

Create a new knowledge base, optionally importing from BibTeX.

perspicacite -c config.yml create-kb NAME [--description TEXT] [--from-bibtex FILE]
Flag Description
NAME (positional) KB name (alphanumeric + hyphens/underscores)
--description, -d TEXT Human-readable description
--from-bibtex, -b FILE BibTeX file to import on creation
--session-db PATH Override default SQLite path
--chroma-dir PATH Override default Chroma directory

Without --from-bibtex, creates an empty KB. Papers can be added later with add-to-kb or via the REST API.

add-to-kb
