sigit-si-cli

si is the command line interface for sigit.si — sign in, manage repositories, review pull requests, triage issues, search code, and drive Cloud Sessions, all from the terminal.

Install

cargo install --path crates/cli

This installs a binary named si.

Related MCP server: SwarmMojo MCP Server

Usage

si auth login                     # sign in with your sigit.si account
si repo list                      # your repositories
si repo create my-project --private
si repo clone seto/my-project      # clone with your sign-in, no token in the URL
si auth setup-git                  # or let plain `git clone` use it too

# Inside a repo checkout, si infers OWNER/NAME from the sigit.si git remote —
# --repo is only needed when you're not standing in one.
si pr list
si pr view 42
si pr create --title "Fix the thing" --base main

si issue list --state open
si issue create --title "Bug: ..." --body "Steps to reproduce..."

si code search "TODO" --ref main
si code view README.md

si status set HEAD --state success --context ci/test
si status view                     # the checks on HEAD

si run start --repo seto/app "Fix the failing build"
si run list
si run view 12                     # status and the end of the transcript

si site publish --wait             # publish the default branch as a site
si site view

si session new --title "Refactor auth"
si models
si billing show

si auth signup                     # also: resend, reset-password, delete-account

si browse                          # open the current repo on sigit.si
si api repos                       # raw escape hatch for any endpoint

Pass --json to any read command for machine-readable output.

As an MCP server

si mcp serves these same commands to an AI agent as MCP tools over stdio:

{
  "mcpServers": {
    "sigit": { "command": "si", "args": ["mcp"] }
  }
}

There is nothing to authenticate — the server reuses the token si auth login stored. Point your editor at the directory of a checkout and repository tools default to the repo you're standing in, so the agent can say "list the open pull requests" without naming one; create_pull_request likewise defaults its head to the checked-out branch.

Trim the tool list when an agent doesn't need all of it:

si mcp --read-only                    # drop every tool that writes
si mcp --toolsets repo,issue,pr,code  # or SIGIT_TOOLSETS=repo,issue

Toolsets are account, repo, issue, pr, code, hook, session, and billing. sigit.si also hosts a remote MCP server at /api/v1/mcp for clients that would rather connect over HTTP than spawn a binary.

Environments

si --environment dev repo list          # a local sigit.si server (localhost:3000)
SIGIT_HOST=staging.example.com si repo list

Credentials are stored per-environment in ~/.sigit/token (or ~/.sigit-dev/token). SIGIT_TOKEN overrides the stored token, which is how CI authenticates without an interactive login.

Workspace layout

• crates/sigit-si-api — a standalone, typed Rust client for the sigit.si JSON API. No CLI dependencies (clap, dialoguer, …); usable from any Rust project that wants to talk to sigit.si.

• crates/cli — the si binary: command parsing, terminal rendering, git remote resolution, and credential storage, built on top of sigit-si-api.

Issues, pull requests, and code search have no REST surface on sigit.si yet — they're served over the same MCP (Model Context Protocol) JSON-RPC endpoint the AI agent uses. sigit-si-api speaks that transport internally; it's not visible at the call site.

MCP Registry listings

This repo publishes two entries to the official MCP Registry, one per way of reaching the same tools, so registry-aware clients can add either in one click:

The CLI holds server.json because it's what this repo ships, and that's the filename mcp-publisher defaults to. Sibling listings are named after their own leaf, so the file says which entry it publishes.

Both go out through the release-mcp-registry.yml workflow, and both prove namespace ownership with a DNS TXT record on sigit.si rather than GitHub OIDC, so one credential covers the pair. A package listing has a second hurdle: the registry fetches the crate from crates.io and looks for the mcp-name: si.sigit/cli marker in its README, which is why that marker sits in this file. Crate versions are immutable, so a release that ships without the marker can never be listed, and fixing it costs a new version. The internal setup and release runbook live with the server (private sigit-si repo).

To cut a release, bump [workspace.package].version and the sigit-si-api dependency in the root Cargo.toml, merge development into main, and push a vX.Y.Z tag. release-crates.yml checks the crate versions against the tag, publishes whichever of sigit-si-api and sigit-si-cli isn't on crates.io yet (through Trusted Publishing, so no token is stored), then dispatches release-mcp-registry.yml.
