description	Configures MCP servers for projects. Use when setting up Linear, GitHub, Chrome DevTools, Render, or other MCP servers for a project. Handles token selection and configuration.

MCP Project Configuration

Guide for configuring MCP (Model Context Protocol) servers in projects.

Standard MCP Servers

Every project should include these MCP servers:

Server	Type	Purpose
Linear	HTTP	Project/issue tracking
GitHub	HTTP	Code management
Chrome DevTools	stdio	Browser debugging
Render	HTTP	Deployment management

Configuration Files

.mcp.json (Project Root)

MCP server definitions with environment variable substitution:

{
  "mcpServers": {
    "linear": {
      "type": "http",
      "url": "https://mcp.linear.app/mcp",
      "headers": {
        "Authorization": "Bearer ${LINEAR_TOKEN_VAR}"
      }
    },
    "github": {
      "type": "http",
      "url": "https://api.githubcopilot.com/mcp",
      "headers": {
        "Authorization": "Bearer ${GITHUB_PERSONAL_ACCESS_TOKEN}"
      }
    },
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    },
    "render": {
      "type": "http",
      "url": "https://mcp.render.com/mcp",
      "headers": {
        "Authorization": "Bearer ${RENDER_TOKEN}"
      }
    }
  }
}

.claude/settings.json

Enable MCP servers for Claude Code:

{
  "enableAllProjectMcpServers": true,
  "enabledMcpjsonServers": ["linear", "github", "chrome-devtools", "render"]
}

Linear Account Selection

When setting up Linear, ask which account to use:

Known Accounts

Account	Token Variable
Laser Focused	LASER_FOCUSED_LINEAR_TOKEN
What If	WHAT_IF_LINEAR_TOKEN

New Workspace

If neither account applies:

1. Ask user for the token environment variable name
2. User creates the token at https://linear.app/settings/api
3. User adds to their shell profile (~/.zshrc or ~/.bashrc)

Configuration

Replace LINEAR_TOKEN_VAR in .mcp.json with the chosen variable:

"linear": {
  "type": "http",
  "url": "https://mcp.linear.app/mcp",
  "headers": {
    "Authorization": "Bearer ${LASER_FOCUSED_LINEAR_TOKEN}"
  }
}

Token Environment Setup

Tokens should be stored in the user's shell profile, NOT in project files.

Where to Store Tokens

Add to ~/.zshrc or ~/.bashrc:

# Linear API Tokens
export LASER_FOCUSED_LINEAR_TOKEN="lin_api_..."
export WHAT_IF_LINEAR_TOKEN="lin_api_..."

# GitHub Personal Access Token
export GITHUB_PERSONAL_ACCESS_TOKEN="ghp_..."

# Render API Token
export RENDER_TOKEN="rnd_..."

Reload After Adding

source ~/.zshrc  # or ~/.bashrc

MCP Server Types

HTTP Servers

Use for hosted APIs with authentication:

{
  "type": "http",
  "url": "https://api.service.com/mcp",
  "headers": {
    "Authorization": "Bearer ${TOKEN_VAR}"
  }
}

stdio Servers (npx)

Use for local tools that run as processes:

{
  "command": "npx",
  "args": ["-y", "package-name@latest"]
}

stdio Servers (Local Binary)

Use for installed binaries:

{
  "command": "/path/to/binary",
  "args": ["--flag", "value"]
}

Setup Workflow

Step 1: Create .mcp.json

# In project root
touch .mcp.json

Step 2: Ask About Linear Account

"Which Linear workspace is this project for?"

• Laser Focused (LASER_FOCUSED_LINEAR_TOKEN)
• What If (WHAT_IF_LINEAR_TOKEN)
• New workspace (provide token name)

Step 3: Configure All Servers

See mcp-templates.md for full templates.

Step 4: Create .claude/settings.json

mkdir -p .claude

Add settings to enable MCP servers.

Step 5: Verify

Start a new Claude Code session and verify MCP tools are available.

Adding Custom MCP Servers

To add a new MCP server:

1. Determine the server type (HTTP or stdio)
2. Get the URL or command
3. Identify required authentication
4. Add to .mcp.json
5. Add server name to enabledMcpjsonServers in settings.json

Troubleshooting

MCP Server Not Available

1. Check token is exported: echo $TOKEN_NAME
2. Verify .mcp.json syntax (valid JSON)
3. Check server is listed in settings.json
4. Restart Claude Code session

Authentication Failed

1. Verify token is valid (not expired)
2. Check token has required permissions
3. Ensure environment variable is set

HTTP Server Connection Failed

1. Check URL is correct
2. Verify network connectivity
3. Check if service is operational
