Debugging Agent

Connects to the Multiplayer backend and automatically resolves incoming issues using AI.

multiplayer [agent] [options]

Options are resolved in this order: CLI flag → environment variable → config profile.

| Flag | Env var | Description | |------|---------|-------------| | --api-key <key> | MULTIPLAYER_API_KEY | Multiplayer API key | | --dir <path> | MULTIPLAYER_DIR | Project directory (must be a git repo) | | --model <name> | AI_MODEL | AI model (e.g. claude-sonnet-4-6, gpt-4o) | | --model-key <key> | AI_API_KEY | AI provider API key (not required for Claude models) | | --model-url <url> | AI_BASE_URL | Base URL for OpenAI-compatible APIs | | --headless | MULTIPLAYER_HEADLESS=true | Run without TUI — outputs structured JSON logs | | --profile <name> | MULTIPLAYER_PROFILE | Config profile to load (default: default) | | --name <name> | MULTIPLAYER_AGENT_NAME | Agent name (defaults to hostname) | | --max-concurrent <n> | MULTIPLAYER_MAX_CONCURRENT | Max issues resolved in parallel (default: 2) | | --no-git-branch | MULTIPLAYER_NO_GIT_BRANCH=true | Work in current branch — no worktree, no push | | --health-port <port> | MULTIPLAYER_HEALTH_PORT | HTTP health check port (headless mode only) | | --url <url> | MULTIPLAYER_URL | Multiplayer API base URL |

TUI mode (default)

An interactive terminal dashboard that shows active sessions and live logs.

multiplayer --api-key <key> --dir /path/to/repo --model claude-sonnet-4-6

Headless mode

Outputs newline-delimited JSON logs — suitable for CI, containers, and log aggregators.

multiplayer --headless --api-key <key> --dir /path/to/repo --model claude-sonnet-4-6

In headless mode, SIGTERM waits for active sessions to finish before exiting; SIGINT exits immediately.

Config profiles

Create a .multiplayer/config file in your project directory or home directory (~/.multiplayer/config). Uses INI format — the same as AWS credentials.

[default]
api_key        = <your-api-key>
dir            = /path/to/repo
model          = claude-sonnet-4-6
max_concurrent = 2

[staging]
api_key        = <staging-api-key>
dir            = /path/to/staging-repo
model          = gpt-4o
model_key      = <openai-api-key>

All supported profile keys:

| Key | Description | |-----|-------------| | api_key | Multiplayer API key | | dir | Project directory | | model | AI model name | | model_key | AI provider API key | | model_url | Base URL for OpenAI-compatible APIs | | name | Agent name | | url | Multiplayer API base URL | | max_concurrent | Max parallel issues | | no_git_branch | true to skip branch/worktree creation |

Auth

multiplayer auth login    # Log in via browser OAuth flow
multiplayer auth logout   # Log out and clear stored credentials
multiplayer auth status   # Check current authentication status

Releases

multiplayer releases create [options]

| Flag | Env var | Description | |------|---------|-------------| | --api-key <key> | MULTIPLAYER_API_KEY | Multiplayer API key | | --service <name> | SERVICE_NAME | Service name | | --release-version <version> | RELEASE | Release version | | --commit-hash <hash> | COMMIT_HASH | Commit hash | | --repository-url <url> | REPOSITORY_URL | Repository URL | | --release-notes <notes> | RELEASE_NOTES | Release notes (optional) | | --base-url <url> | BASE_URL | API base URL (optional) |

Example:

multiplayer releases create \
  --api-key $MULTIPLAYER_API_KEY \
  --service my-service \
  --release-version 1.2.3 \
  --commit-hash abc123 \
  --repository-url https://github.com/org/repo

Deployments

multiplayer deployments create [options]

| Flag | Env var | Description | |------|---------|-------------| | --api-key <key> | MULTIPLAYER_API_KEY | Multiplayer API key | | --service <name> | SERVICE_NAME | Service name | | --release <version> | RELEASE | Release version | | --environment <name> | ENVIRONMENT | Environment name | | --base-url <url> | BASE_URL | API base URL (optional) |

Example:

multiplayer deployments create \
  --api-key $MULTIPLAYER_API_KEY \
  --service my-service \
  --release 1.2.3 \
  --environment production

Sourcemaps

multiplayer sourcemaps upload <directories...> [options]

| Flag | Env var | Description | |------|---------|-------------| | --api-key <key> | MULTIPLAYER_API_KEY | Multiplayer API key | | --service <name> | SERVICE_NAME | Service name | | --release <version> | RELEASE | Release version | | --base-url <url> | BASE_URL | API base URL (optional) |

Example:

multiplayer sourcemaps upload ./dist ./build \
  --api-key $MULTIPLAYER_API_KEY \
  --service my-service \
  --release 1.2.3

MCP Server

multiplayer mcp starts an MCP server over stdio, exposing Multiplayer operations as tools that AI agents (Claude Desktop, Claude Code, Cursor, etc.) can call directly.

Tools

| Tool | Description | |------|-------------| | create_release | Register a release for a service | | create_deployment | Deploy a release to an environment | | upload_sourcemaps | Upload .map files from local directories |

Setup

Add the server to your MCP client config. Example for Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "multiplayer": {
      "command": "multiplayer",
      "args": ["mcp"],
      "env": {
        "MULTIPLAYER_API_KEY": "<your-api-key>"
      }
    }
  }
}

Example for Claude Code (~/.claude/mcp.json):

{
  "mcpServers": {
    "multiplayer": {
      "command": "multiplayer",
      "args": ["mcp"],
      "env": {
        "MULTIPLAYER_API_KEY": "<your-api-key>"
      }
    }
  }
}

Once configured, the AI can create releases, deployments, and upload sourcemaps without any shell commands or manual steps.
