Drive Ganty
directly from Claude.

Ganty supports the Model Context Protocol (MCP). Use natural language in Claude Desktop, Claude Code, Cursor, and other MCP clients to read and modify Gantt chart tasks.

What you can ask Claude

Summarize a project

"Summarize the E-Commerce redesign project. What's blocking us right now?"

Bulk-create tasks

"In project X, create tasks for requirements, design, implementation, QA, and launch in sequence."

Update progress in bulk

"Update all design-related tasks to 50%."

Surface risks

"Which tasks must finish this week to keep the critical path?"

Setup

Step 1: Generate an API token

Sign in to Ganty, then go to Settings → API Tokens and create a new token. Copy the generated token (gnty_...) immediately — it can't be shown again.

Step 2: Configure your MCP client

Claude Desktop

Open Settings → Developer → MCP config file and add:

{
  "mcpServers": {
    "ganty": {
      "type": "http",
      "url": "https://ganty.app/api/mcp",
      "headers": {
        "Authorization": "Bearer gnty_YOUR_TOKEN_HERE"
      }
    }
  }
}

Claude Code

Run the following command in your terminal:

claude mcp add --transport http ganty https://ganty.app/api/mcp \
  --header "Authorization: Bearer gnty_YOUR_TOKEN_HERE"

Cursor / その他のMCPクライアント

Any MCP client supporting Streamable HTTP transport can connect using the URL and Bearer header above. Protocol version 2025-06-18 (backward-compatible with older versions).

Step 3: Talk to Claude

Once connected, you can ask Claude things like:

  • • "List my Ganty workspaces."
  • • "Show all not-started tasks in project X."
  • • "Update task A's progress to 80%."
  • • "Create a new task "QA Testing" from June 1 for 3 days."

Security

Token scope: Tokens have read/write access to all workspaces and projects the issuing user can access. Write permissions are gated by your workspace role.

Audit log: All write operations are recorded in the audit log (Business plan and above).

Revocation: Revoke unused or compromised tokens immediately from the settings page.

Hashing: Tokens are stored as SHA-256 hashes. Even Ganty admins cannot recover raw tokens.
