Cli MCP Server vs Forge
In-depth architectural comparison of the Cli MCP Server and Forge MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Cli MCP Server
Command Line · Local stdio
Quality: 40/100 (Fair) | Auth: No auth required
Forge
Command Line · Local stdio
Quality: 61/100 (Good) | Auth: No auth required
Verdict Summary: Choose Cli MCP Server if you need specialized Command Line tools running via a local process. Choose Forge if your workspace requires Command Line integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Cli MCP Server when:
You need dedicated capabilities in the Command Line domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
You have access to required keys: ALLOWED_DIR, ALLOWED_COMMANDS, ALLOWED_FLAGS, MAX_COMMAND_LENGTH, COMMAND_TIMEOUT, ALLOW_SHELL_OPERATORS.
Command line interface with secure execution and customizable security policies
Terminal MCP server for AI coding agents with persistent PTY sessions, ring-buffer incremental reads, headless xterm screen capture, multi-agent orchestration, and a real-time web dashboard.
Cli MCP Server is categorized under Command Line and uses a local stdio subprocess. In contrast, Forge belongs to Command Line using local stdio subprocess. Select Cli MCP Server when you need capabilities focused on command line and Forge when you require tools for command line.
Recreate a previously exited terminal session with the same command, working directory, name, tags, and dimensions. The old session is removed and a fresh one is spawned.
create_from_template
Create a terminal session from a pre-configured template (e.g., shell, next-dev, vite-dev, npm-test).
list_templates
List all available session templates.
spawn_claude
Spawn a Claude Code agent in a new terminal session. IMPORTANT: cwd must be set explicitly — there is no session inheritance. By default runs in interactive mode — the session stays alive and accepts follow-up messages via the dashboard. Use oneShot: true for autonomous --print mode. Use worktree + branch to run in an isolated git worktree.
spawn_codex
Spawn a Codex agent in a new terminal session. By default runs in interactive mode — the session stays alive and accepts follow-up messages via the dashboard. Use oneShot: true for autonomous `codex exec` mode (requires prompt).
spawn_gemini
Spawn a Gemini CLI agent in a new terminal session. By default runs in interactive mode — the session stays alive and accepts follow-up messages via the dashboard. Use oneShot: true for headless mode (requires prompt).
write_terminal
Send input to a terminal session. Appends newline by default. Use submit=true for Claude Code sessions (sends Escape+Enter to exit multi-line mode and submit).
read_terminal
Read NEW output from a terminal since last read (incremental). Token-efficient — only returns what changed.
read_screen
Read the current terminal viewport as rendered text (no ANSI codes). Shows what a human would see on screen.
grep_terminal
Search terminal output buffer with a regex pattern. Returns matching lines with optional context.
wait_for
Wait for a regex pattern to appear in terminal output, OR wait for the process to exit. Checks existing buffer/status first, then watches live. Use waitForExit: true for commands that terminate (builds, tests, installs).
