From the repository
No installation is needed – the client downloads the package on first launch via npx humantone-mcp. Configure the MCP client with a JSON snippet that sets command to npx, args to ["-y", "humantone-mcp"], and env with your HUMANTONE_API_KEY. Then restart the client and prompt the assistant naturally to use the tools.

There is no install step. The MCP client downloads the package on first launch vianpx humantone-mcp. Just add the configuration snippet for your client below.
- macOS:~/Library/Application Support/Claude/claude_desktop_config.json
- Windows:%APPDATA%\Claude\claude_desktop_config.json
- Linux:~/.config/Claude/claude_desktop_config.json
{ "mcpServers": { "humantone": { "command": "npx", "args": ["-y", "humantone-mcp"], "env": { "HUMANTONE_API_KEY": "ht_your_api_key_here" } } } }
Restart Claude Desktop after editing the file.
Configure via Settings then MCP, or by editing~/.cursor/mcp.jsondirectly.
{ "mcpServers": { "humantone": { "command": "npx", "args": ["-y", "humantone-mcp"], "env": { "HUMANTONE_API_KEY": "ht_your_api_key_here" } } } }
Restart Cursor after editing the configuration.
Configure via Cline Settings then MCP Servers, with the same snippet structure:
{ "mcpServers": { "humantone": { "command": "npx", "args": ["-y", "humantone-mcp"], "env": { "HUMANTONE_API_KEY": "ht_your_api_key_here" } } } }
Restart VSCode after editing the configuration.
humantone-mcp works with any MCP-compatible client, including VSCode with GitHub Copilot agent mode, Codex CLI, Gemini CLI, Continue.dev, Zed, Windsurf, JetBrains AI Assistant, and others. The configuration pattern is the same across clients: a command (npx -y humantone-mcp) withHUMANTONE_API_KEYin the environment.
Seehumantone.io/docs/mcp/for client-specific setup snippets and troubleshooting.
- humanizerewrites text to sound more natural and human-written. Supports custom instructions for tone, audience, and terminology.
- detect_aichecks AI likelihood of text (0 to 100). Does not consume credits. 30 checks per day, shared with the HumanTone web app.
- get_accountshows current plan, credits, and subscription status.
Once configured, talk to your assistant naturally. Mentioninghumantoneor specific tool names in your message helps the model reliably route to the MCP tool, especially for humanize requests where the model could otherwise rewrite the text itself.
- "Use humantone to rewrite this draft so it reads more naturally: <!-- -->"
- "Run this through humantone with a formal corporate tone: <!-- -->"
- "Pass this to humantone, set level to advanced, and preserve the term Kubernetes intact: <!-- -->"
- "Use humantone's AI detector to score this paragraph: <!-- -->"
- "Check AI likelihood with humantone: <!-- -->"

- "How many HumanTone credits do I have left?"
- "What is my current HumanTone plan?"
- "When does my HumanTone subscription renew?"
- Tools do not appear in the assistant.Confirm the JSON config has no syntax errors, then fully quit and reopen the client. A window refresh is not enough.
