langchain-agentx-cli

AgentX Code — Terminal AI coding assistant with Claude Code compatible TUI.

依托 langchain-agentx-python SDK,提供功能完整的终端编码助手。

Installation

pip install langchain-agentx-cli

Requires Python 3.11+ and ANTHROPIC_API_KEY environment variable.

Quick Start

# Navigate to your project directory
cd ~/my-project

# Start AgentX Code
agentx-code

Environment Setup

# Set your Anthropic API key
export ANTHROPIC_API_KEY="sk-ant-..."

Command Options

agentx-code                                    # Start in current directory
agentx-code --workspace-root /path/to/project  # Specify workspace
agentx-code --mode agentx|claude|cursor        # Config-home brand mode (see below)
agentx-code --agent-home .cursor               # Or set segment directly (overridden by --mode)
agentx-code --model claude-sonnet-4-6         # Specify model
agentx-code --provider claude | openai        # Choose provider
agentx-code --dangerously-skip-permissions    # Skip permission prompts (CC-aligned)
agentx-code --allowed-tools Read Grep Glob    # Pre-approve tools (space or comma; CC --allowed-tools)
agentx-code --allowed-tools Bash,Skill        # Tier1 scan profile (OPS/new_agent); see SDK A25 R0
agentx-code --disallowed-tools Bash Edit      # Block tools (space or comma; deny wins)
agentx-code --tools Read Grep Glob            # Only these built-ins; others auto-denied (CC --tools)
agentx-code --mcp-config extra-mcp.json       # Load extra MCP servers (file or inline JSON; repeatable; CC --mcp-config)
agentx-code --strict-mcp-config               # Only use --mcp-config servers; skip project .mcp.json discovery
agentx-code -p "summarize README.md"          # One-shot print mode (headless)
agentx-code --show-config                     # Print merged config

Config home mode (agent_home_segment,与 SDK 三模式对齐):

--mode Segment Typical paths
claude(默认) .claude ~/.claude/(与 Claude Code 同构,默认复用其全局配置/skills)
agentx .langchain_agentx ~/.langchain_agentx/、仓库内 .langchain_agentx/
cursor .cursor ~/.cursor/

优先级:--mode > --agent-home > 环境变量 LANGCHAIN_AGENTX_AGENT_HOME > CLI 默认 .claude。只换品牌目录名,不按「目录是否存在」隐式回退。与默认 --provider claude 对齐:裸跑 agentx-code 即走 Claude 配置树。

Read-only audit (aligned with Claude Code CLI semantics):

agentx-code --permission-mode dontAsk \
  --allowed-tools Read,Grep,Glob \
  --disallowed-tools Bash,Edit,WebSearch,WebFetch

MCP (Model Context Protocol)

状态(2026-10-04):CLI 宿主面按 D25 / 实施计划 分阶段落地,P0–P3 整包已交付:mcp add/add-json/list/get/remove 写仓库根 .mcp.json(P0),会话自动装池(project .mcp.json 有 server 即注入,出现 mcp__<server>__<tool> 工具)与 mcp list / mcp get 连接健康检查(P1),/mcp 管理面板 + project server 审批(未审批不连接;Approve/Reject/reconnect/enable/disable)+ mcp reset-project-choices + mcp login --token / mcp logout(P2a),浏览器 OAuth(PKCE:mcp login 打开浏览器 → 粘贴 callback URL;--client-id / --scope 可选)(P2b),启动 flags --mcp-config / --strict-mcp-config 与 mcp serve(默认只读子集 expose;P3)。local/user scope 写入仍待 SDK 提供 write API。

把外部 MCP server 接到 AgentX,用法与 Claude Code MCP 一致。配置生效并完成会话接线后,会出现 mcp__<server>__<tool> 工具。

添加 server

# HTTP(远程)
agentx-code mcp add --transport http docs https://code.claude.com/docs/mcp

# HTTP + 请求头(如 Bearer token)
agentx-code mcp add --transport http github https://api.githubcopilot.com/mcp/ \
  --header "Authorization: Bearer YOUR_TOKEN"

# SSE(远程)
agentx-code mcp add --transport sse asana https://mcp.asana.com/sse

# stdio(本地进程;`--` 后面整段交给 server,不要省略)
agentx-code mcp add --transport stdio filesystem -- \
  npx -y @modelcontextprotocol/server-filesystem .

# stdio + 环境变量
agentx-code mcp add --env API_KEY=xxx --transport stdio airtable -- \
  npx -y @airtable/mcp-server

# 整段 JSON 配置
agentx-code mcp add-json weather '{"type":"http","url":"https://example.com/mcp"}'

管理 server

agentx-code mcp list                 # 列出配置,并做连接健康检查
agentx-code mcp get docs             # 查看某个 server 详情 / 作用域 / 错误
agentx-code mcp remove docs          # 删除(可加 -s/--scope)
agentx-code mcp reset-project-choices  # 重置本项目 .mcp.json 的批准/拒绝选择

# 远程 MCP 的凭据(向 Sentry/Notion 等第三方授权拿 token;不是登录 Claude 账号)
# 浏览器 OAuth(PKCE):打开浏览器授权 → 把跳转到的完整 callback URL 粘贴回终端
agentx-code mcp login sentry
agentx-code mcp login sentry --client-id <ID> --scope "mcp:read"   # 授权服务器需要时显式给出
# 或直接给静态 token(经 SDK submit_token 落当前 mode 的 mcp-oauth.json)
agentx-code mcp login sentry --token <ACCESS_TOKEN>
agentx-code mcp logout sentry
# 若服务商提供长期 token,也可在 add 时用 --header,不必走 login

作用域(-s / --scope)与三 mode

MCP 命令与主程序一样支持 --mode / --agent-home(默认 claude → .claude)。
project 始终写在仓库根 .mcp.json(与 mode 无关);user / local 写在当前 mode 的全局配置根下。

agentx-code mcp add --transport http stripe --scope local https://mcp.stripe.com     # 默认 mode=claude:仅当前项目、私有
agentx-code mcp add --transport http shared --scope project https://example.com/mcp  # 仓库根 .mcp.json,可提交给团队
agentx-code mcp add --transport http hubspot --scope user https://mcp.hubspot.com/anthropic  # 本机所有项目(当前 mode 全局根)

# 显式使用 agentx / cursor 配置树(user/local 落盘目录不同)
agentx-code --mode agentx mcp add --scope user --transport http docs https://example.com/mcp
agentx-code --mode cursor mcp list
Scope 谁能用 写到哪里
local(默认) 仅你 + 当前项目 当前 mode 全局根内、按项目键的条目(默认 ~/.claude/…)
project 克隆仓库的所有人 始终 {workspace}/.mcp.json(不在 .claude/ / .cursor/ 内)
user 仅你 + 所有项目 当前 mode 全局根(~/.claude/ / ~/.langchain_agentx/ / ~/.cursor/)
--mode Segment 全局根(user/local) 工程内 agent home
claude(默认) .claude ~/.claude/ {workspace}/.claude/
agentx .langchain_agentx ~/.langchain_agentx/ {workspace}/.langchain_agentx/
cursor .cursor ~/.cursor/ {workspace}/.cursor/

手写项目配置(等价于 --scope project)

在项目根创建 .mcp.json:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "."]
    },
    "docs": {
      "type": "http",
      "url": "https://code.claude.com/docs/mcp"
    }
  }
}

支持 ${VAR} / ${VAR:-default} 环境变量展开。JSON 里 streamable-http 等价于 http。

会话里使用

cd ~/my-project
agentx-code

进入 REPL 后:

/mcp                         # 管理面板:连接状态、审批项目级 server(a Approve / r Reject / c Reconnect)
/mcp reconnect filesystem    # 重连某个 server
/mcp enable filesystem       # 批准并连接(enable all 批量)
/mcp disable filesystem      # 拒绝并断开(disable all 批量)

project .mcp.json 中的 server 首次使用需审批(未审批不连接;选择持久化在用户级 ~/.config/langchain_agentx/mcp_approvals.json,按项目路径键——仓库本身无法自我批准)。 重置本项目的全部审批选择:

agentx-code mcp reset-project-choices

需要限制可用 MCP 工具时:

agentx-code --allowed-tools "mcp__filesystem__*"
agentx-code --disallowed-tools "mcp__docs__*"

把 AgentX 自己暴露成 MCP Server

除了「连出去」用别人的 MCP,也可以让本进程当 Server,把 AgentX 自身能力(工具子集)暴露给 Cursor 或其他 MCP Client:

# 以 stdio 提供 MCP(供外部 Client 的 command 指向本进程)
agentx-code mcp serve

# 显式打开危险工具(默认不暴露 Bash/Edit/Write)
agentx-code mcp serve --allow-tools Bash,Edit

# 调试(日志走 stderr;stdout 是 MCP 协议通道)
agentx-code mcp serve --debug --verbose

在 Cursor / 其他客户端里把 command 配成 agentx-code、args 配成 mcp serve(工作目录设为你的项目)。对方 tools/list 会看到 AgentX 暴露的工具,tools/call 仍走 SDK 执行与权限链。

默认只暴露只读子集 Read / Grep / Glob / WebFetch;Bash / Edit / Write / Skill 等须经 --allow-tools 显式打开(逗号/空格分隔,可重复;未知名会报错并列出可用工具)。

mcp list / mcp get 会对配置的 server 做探测(stdio 会启动进程)。请只在信任的目录中执行。
