Twenty MCP Server
Twenty MCP Server
An MCP server for integrating with Twenty CRM, providing access to Twenty's REST API through categorized tools. The available tools map the entire Twenty REST API and were automatically generated using the openapi-mcp-generator.
CAUTION
Development Version
This server is currently in development and is not recommended for production use. Use at your own risk in production environments.
CAUTION
For local use
This MCP server provides access to your Twenty CRM API using your api-key. It has no built-in authorization, authentication, or access controls.
Tool Filtering
This MCP server supports both category-based and individual tool filtering, allowing you to selectively enable only the tools you need. This approach significantly reduces context window usage and improves performance.
Available Categories
| Category | Description |
|---|---|
api-schema | API Schema & Metadata |
crm | CRM & Contact Management |
tasks | Task & Project Management |
notes | Notes & Documentation |
attachments | File Attachments |
calendar | Calendar & Events |
messaging | Messaging & Communication |
preferences | User Preferences & Organization |
views | Data Views & Filtering |
workflow | Workflow & Automation |
system | System & Admin |
Available Tools
All available tools can be found in the Twenty REST API schema at https://your-twenty-instance.com/rest under the operationId field. You can either:
- Download the OpenAPI specification from your Twenty instance, or
- Browse tool definitions directly in this repository under the
/src/tools/directory
Usage
MCP Client Configuration
When configuring this server in an MCP client (like Claude Desktop), you can use category and/or specific tool arguments to control which tools are available.
TIP
Performance Recommendation
It's highly recommended to limit the available tools to only what you need. This reduces the context window size required to display available tools, improving both performance and cost efficiency.
NOTE
The tools defined in the "Using Specific Tools" example below represent my currently used tool setup.
Using Categories
Filter tools by predefined categories:
{
"mcpServers": {
"twenty": {
"command": "node",
"args": [
"/path/to/twenty-mcp-server/build/index.js",
"--category=crm,tasks,notes"
],
"env": {
"TWENTY_BASE_URL": "https://your-twenty-instance.com/rest",
"TWENTY_API_KEY": "your-api-key"
}
}
}
}
Using Specific Tools
Select individual tools by their names:
{
"mcpServers": {
"twenty": {
"command": "node",
"args": [
"/path/to/twenty-mcp-server/build/index.js",
"--tools=findManyCompanies,createOneCompany,findOneCompany,UpdateOneCompany,findManyPeople,createOnePerson,findOnePerson,UpdateOnePerson,findManyTasks,createOneTask,createManyTasks,findOneTask,UpdateOneTask"
],
"env": {
"TWENTY_BASE_URL": "https://your-twenty-instance.com/rest",
"TWENTY_API_KEY": "your-api-key"
}
}
}
}
Combining Categories and Specific Tools
Use both approaches together:
{
"mcpServers": {
"twenty": {
"command": "node",
"args": [
"/path/to/twenty-mcp-server/build/index.js",
"--category=crm,tasks",
"--tools=findManyAttachments,createOneAttachment"
],
"env": {
"TWENTY_BASE_URL": "https://your-twenty-instance.com/rest",
"TWENTY_API_KEY": "your-api-key"
}
}
}
}
Default Behavior
NOTE
Default Configuration
If neither --category nor --tools arguments are provided, all categories are enabled by default. This gives you access to the complete Twenty API but will impact performance and costs due to the large number of available tools.
