JetBrains AI Assistant

Add to your JetBrains AI Assistant MCP configuration (see official docs for the exact path):

Getting Your GitBook Credentials

API Token: Visit https://app.gitbook.com/account/developer to generate your API token
Organization ID: Use the list_organizations tool after setup to find your organization ID
Space ID (optional): Use the list_spaces tool (requires a valid organization ID and API token) to find specific space IDs
Space ID (optional): Use the list_spaces tool to find specific space IDs

Configuration Options

You can configure the server using:

CLI arguments: --organization-id, --space-id
Environment variables in MCP config: Set via the env object in your MCP configuration
System environment variables: GITBOOK_API_TOKEN, GITBOOK_ORGANIZATION_ID, GITBOOK_SPACE_ID

Note: .env files are only supported when running the server locally for development, not when using npx gitbook-mcp.

Configuration Reference

The GitBook MCP server supports multiple configuration methods with the following precedence (highest to lowest):

CLI Arguments - Passed when starting the MCP server
Configuration Files - Embedded in project configuration files
Environment Variables - Set in .env.local or system environment

Environment Variables

Variable	Required	Type	Description
`GITBOOK_API_TOKEN`	Yes	string	GitBook API token (obtain from https://app.gitbook.com/account/developer)
`GITBOOK_ORGANIZATION_ID`	No	string	Default organization ID for operations
`GITBOOK_SPACE_ID`	No	string	Default space ID for single-space projects

Note: Environment variables can be set in .env.local, .env, or your system environment.

CLI Arguments

Argument	Alias	Type	Description
`--organization-id`	`--org`	string	Organization ID to work with
`--space-id`	`--space`	string	Default space for operations

Example:

node dist/index.js --organization-id your-org-id --space-id your-space-id

Additional Configuration Files

Typically these files are provided as context to the AI assistant, which means you can store project-based configuration.

.github/copilot-instructions.md
.cursorrules
.cursor/rules/rules.md
.cursor/rules/instructions.md

e.g.

Format:

## GitBook Configuration

For GitBook MCP operations, use the following configuration:

- organization-id: your-org-id-here
- space-id: your-space-id-here

Default Parameter Behavior

When GITBOOK_ORGANIZATION_ID or GITBOOK_SPACE_ID are configured:

Tools marked as "optional" can omit the corresponding ID parameters
The configured default values will be used automatically
Explicit parameters in tool calls override defaults

Development

Prerequisites

Node.js 20+
npm
GitBook API token (obtain from https://app.gitbook.com/account/developer)

Installation & Setup

git clone https://github.com/rickysullivan/gitbook-mcp.git
cd gitbook-mcp
npm install
npm run setup
# Add your GITBOOK_API_TOKEN to .env.local (for local development only)

Development

npm run dev

Debugging

DEBUG=1 npm run dev

Add the MCP to VS Code for development

You will need to use node as the command when running locally. The first arg should be the path to the compiled JavaScript output (e.g., dist/index.js).

{
    "servers": {
        "gitbook-mcp-dev": {
            "type": "stdio",
            "command": "node",
            "args": [
                "/my/path/to/gitbook-mcp/dist/index.js",
                "--organization-id=Luj2l6y6cIUPXJwbC574"
            ],
            "env": {
                "GITBOOK_API_TOKEN": "gb_api_UHEGTNsMg0ONPTnm0LpsJNBCCikQyOMkBTtZNDAB"
            }
        }
    }
}

Testing

There are currently no unit or integration tests; running npm run test only checks that the TypeScript code compiles successfully (type-check/build verification), and does not execute any actual tests.

npm run test

Error Handling

Common Error Codes

Error Code	Description	Resolution
`401`	Unauthorized - Invalid API token	Verify `GITBOOK_API_TOKEN` is correct
`403`	Forbidden - Insufficient permissions	Check space/organization access permissions
`404`	Not Found - Resource doesn't exist	Verify space/page/collection IDs are correct
`429`	Rate Limited - Too many requests	Implement request throttling
`500`	Internal Server Error	Check server logs for detailed error information

Troubleshooting

Token Issues:

Ensure token starts with gb_live_
Verify token has not expired
Check token permissions in GitBook settings

ID Resolution:

Use list_organizations to find valid organization IDs
Use list_spaces to find valid space IDs
Use get_space_content to find valid page IDs

Configuration Issues:

Verify environment variables are properly set
Check file permissions on configuration files
Ensure CLI arguments are properly formatted
