Allows LLM to interact with Linear's API via a single static binary.

Linear MCP Server

A Model Context Protocol (MCP) server for Linear, written in Go. This server provides tools for interacting with the Linear API through the MCP protocol.

Features

Create, update, and search Linear issues
Get issues assigned to a user
Add comments to issues
Retrieve team information
Rate-limited API requests to respect Linear's API limits

Prerequisites

Go 1.23 or higher
Linear API key

Installation

From Releases

Pre-built binaries are available for Linux, macOS, and Windows on the GitHub Releases page.

Download the appropriate binary for your platform
Make it executable (Linux/macOS):

chmod +x linear-mcp-go-*

Run the binary as described in the Usage section

Automated

# Download linux binary for the latest release
RELEASE=$(curl -s https://api.github.com/repos/geropl/linear-mcp-go/releases/latest)
DOWNLOAD_URL=$(echo $RELEASE | jq -r '.assets[] | select(.name | contains("linux")) | .browser_download_url')
curl -L -o ./linear-mcp-go $DOWNLOAD_URL
chmod +x ./linear-mcp-go

# Setup the mcp server (.gitpod.yml, dotfiles repo, etc.)
./linear-mcp-go setup --tool=cline

Usage

Running the Server

Set your Linear API key as an environment variable:

export LINEAR_API_KEY=your_linear_api_key

Run the server:

# Run in read-only mode (default)
./linear-mcp-go serve

# Run with write access enabled
./linear-mcp-go serve --write-access

The server will start and listen for MCP requests on stdin/stdout.

Setting Up for AI Assistants

The

setup

command automates the installation and configuration process for various AI assistants:

# Set your Linear API key as an environment variable
export LINEAR_API_KEY=your_linear_api_key

# Set up for Cline (default)
./linear-mcp-go setup

# Set up with write access enabled
./linear-mcp-go setup --write-access

# Set up with auto-approval for read-only tools
./linear-mcp-go setup --auto-approve=allow-read-only

# Set up with specific tools auto-approved
./linear-mcp-go setup --auto-approve=linear_get_issue,linear_search_issues

# Set up with write access and auto-approval for read-only tools
./linear-mcp-go setup --write-access --auto-approve=allow-read-only

# Set up for a different tool (only "cline" supported for now)
./linear-mcp-go setup --tool=cline

This command:

Checks if the Linear MCP binary is already installed
Copies the current binary to the installation directory if needed
Configures the AI assistant to use the Linear MCP server
Sets up auto-approval for specified tools if requested

The

--auto-approve

flag can be used to specify which tools should be auto-approved in the Cline configuration:

--auto-approve=allow-read-only

: Auto-approves all read-only tools (

linear_search_issues

linear_get_user_issues

linear_get_issue

linear_get_teams

)

```
--auto-approve=tool1,tool2,...
```
: Auto-approves the specified comma-separated list of tools

Currently supported AI assistants:

Cline (VSCode extension)

By default, the server runs in read-only mode, which means the following tools are disabled:

```
linear_create_issue
```
```
linear_update_issue
```
```
linear_add_comment
```

To enable these tools, use the

--write-access=true

flag.

Test

Tests are implemented using

go-vcr

, and executed against https://linear.app/linear-mcp-go-test.

Execute tests

Using the existing recordings (cassettes):

go test -v ./...

Re-recording test:

Requires

LINEAR_API_KEY

to be set.

go test -v -record=true ./...

This will update all tests that don't alter remote state.

go test -v -recordWrites=true ./...

This will re-run all tests, including some that might alter the outcome of other tests cases, which might require further manual work to adjust.

go test -v -golden=true ./...

Updates all .golden fields.

Release Process

The project uses GitHub Actions for automated testing and releases:

All pushes to the main branch and pull requests are automatically tested
When a tag matching the pattern
```
v*
```
(e.g.,
```
v1.0.0
```
) is pushed, a new release is automatically created
Binaries for Linux, macOS, and Windows are built and attached to the release
