• Safe, atomic file downloads with conflict policy (fail/skip/overwrite)

Install

Requirements:

• Go 1.26 or newer

go install github.com/edithatogo/osf-cli-go/cmd/osf@latest
go install github.com/edithatogo/osf-cli-go/cmd/osf-mcp@latest

Or from a local checkout:

go build -o bin\osf.exe ./cmd/osf
go build -o bin\osf-mcp.exe ./cmd/osf-mcp
.\scripts\build.ps1

Authentication

Set OSF_TOKEN in your shell session. Do not commit the token or write it into project files. OSF_USERNAME and OSF_PASSWORD are supported as an opt-in fallback credential source, but personal access tokens remain preferred for automation and for accounts using SSO or two-factor authentication.

$env:OSF_TOKEN = '<your-token>'

For guided token setup:

osf auth login

Quick Start

osf --help
osf auth whoami
osf projects list
osf projects get https://osf.io/abc12/
osf components list abc12
osf files list abc12
osf files download --file <file-id> ./output/
osf files download --tree abc12 ./output/
osf files upload --node abc12 ./report.pdf
osf search "open science"
osf preprints list
osf registrations create abc12 --schema <schema-id> --title "Analysis plan"
osf export abc12 --json

MCP Server

osf-mcp runs a stdio MCP server with read-only tools: osf_whoami, osf_projects_list, osf_project_get, osf_components_list, osf_files_list, and osf_contributors_list.

Local development configs are included for GitHub Copilot, VS Code, Claude, Codex, Gemini CLI, and Qwen Code. Public registry metadata is in server.json and registry/.

Output Modes

All commands support --output table|json and --json shorthand:

osf projects list --json
osf auth whoami --output json

Project Status

The CLI is offline-tested for read-only operations, file downloads, WaterButler write primitives, search, preprint listing, draft registration creation, project create/update/delete operations, and node export. All Conductor tracks are reconciled against their per-track plans with closeout review evidence; live OSF validation remains opt-in because it requires credentials and network access.
