claude-mcp-server

MCP server wrapping Claude CLI — lets Cursor (or any MCP host) use Claude as a sub-agent.

Install

One command — no clone needed:

bash <(curl -fsSL https://raw.githubusercontent.com/tal-hason/claude-mcp-server/main/install.sh)

This downloads the latest pre-built release, installs the Cursor extension, and registers the MCP server.

Prerequisites: Node.js >= 20, jq, curl, Claude CLI

Install from source

git clone https://github.com/tal-hason/claude-mcp-server.git
cd claude-mcp-server
./setup.sh

Requires npm in addition to the prerequisites above.

Custom install location

CLAUDE_MCP_DIR=~/my-tools/claude-mcp bash <(curl -fsSL https://raw.githubusercontent.com/tal-hason/claude-mcp-server/main/install.sh)

Uninstall

rm -rf ~/.local/share/claude-mcp-server
jq 'del(.mcpServers["claude-cli"])' ~/.cursor/mcp.json > /tmp/mcp.json && mv /tmp/mcp.json ~/.cursor/mcp.json
cursor --uninstall-extension thason.claude-cli-panel

Related MCP server: claude-bridge

Usage

Single tool: claude_prompt with an optional mode parameter.

claude_prompt({ prompt: "Review this code", mode: "reviewer" })

Modes

Without mode, the tool passes through raw (caller controls everything).

Parameters

How it works

1. Cursor calls the MCP tool via stdio

2. The server resolves mode defaults (effort, appended system prompt)

3. Spawns claude --print --output-format stream-json with the resolved args

4. Parses streaming output, sends MCP progress notifications

5. Returns the final text result + session ID

Claude CLI reads ~/.claude/CLAUDE.md as global context regardless of cwd. Mode system prompts are appended (via --append-system-prompt), never replacing CLAUDE.md.
