Overview

AI-generated overview

Remote MCP server for siGit (sigit.si) that lets an assistant browse repositories, search code, and manage pull requests and issues.

What you can do
  • List, create and clone repositories, and publish a branch as a site
  • Search and view code across a repository at a given ref
  • List, view and create pull requests, defaulting to the checked-out branch
  • List and create issues, and set or view commit status checks
  • Start and inspect Cloud Sessions and runs, and check billing and account details
When to use it
Useful when you work with code hosted on sigit.si and want an assistant to read repositories, search code, or draft pull requests and issues without leaving the chat. Also fits teams already using the siGit CLI or Cloud Sessions.
Requirements
A remote Streamable-HTTP endpoint at sigit.si; OAuth sign-in with a sigit.si account is required. No environment variables or headers are declared.
Before you install
The server can write: creating repositories, pull requests, issues, status checks and sessions changes data on your account. Publishing a site makes a branch publicly reachable. Billing details are exposed through the billing toolset, and the hosted endpoint sees all repository content you query.

Installation

In SourceWeft

  1. Open siGit in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/si.sigit%2Fsigit/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

  "mcpServers": {
    "sigit": {
      "type": "http",
      "url": "https://sigit.si/api/v1/mcp"

  }
}

README

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

sh
cargo install --path crates/cli

This installs a binary named si.

Usage

sh
si auth login                     # sign in with your sigit.si accountsi repo list                      # your repositoriessi repo create my-project --privatesi repo clone seto/my-project      # clone with your sign-in, no token in the URLsi 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 listsi pr view 42si pr create --title "Fix the thing" --base main
si issue list --state opensi issue create --title "Bug: ..." --body "Steps to reproduce..."
si code search "TODO" --ref mainsi code view README.md
si status set HEAD --state success --context ci/testsi status view                     # the checks on HEAD
si run start --repo seto/app "Fix the failing build"si run listsi run view 12                     # status and the end of the transcript
si site publish --wait             # publish the default branch as a sitesi site view
si session new --title "Refactor auth"si modelssi billing show
si auth signup                     # also: resend, reset-password, delete-account
si browse                          # open the current repo on sigit.sisi 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:

jsonc
{  "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:

sh
si mcp --read-only                    # drop every tool that writessi 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

sh
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:

ListingFileWhat it is
si.sigit/cliserver.jsonThis CLI: a cargo package listing that runs si mcp over stdio.
si.sigit/sigitserver-sigit.jsonThe hosted server at sigit.si/api/v1/mcp, a remote Streamable-HTTP listing. The endpoint sigit-si-api talks to, and the official server siGit Code bakes in.

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.
