MCP Server Configuration

Configuration Locations

•User-level config: ~/.claude/settings.json (required for VSCode extension)
•Project-level config: .mcp.json (may not be loaded by VSCode extension)
•Environment file: ~/.claude/.env (copy from project .env)

Important Setup Notes

•
Node.js Required: Install via brew install node (needed for all MCP servers using npx)
•
Use Full Paths: VSCode may not have Homebrew in PATH, so use /opt/homebrew/bin/npx instead of just npx
•
No Variable Interpolation: The ${VAR} syntax does NOT work in ~/.claude/settings.json. You must hardcode actual token values.
•
Restart Required: After changing ~/.claude/settings.json, fully quit VSCode (Cmd+Q) and reopen. A simple reload may not pick up changes.
•
OAuth for Google Services: First run of gdrive/gcal will open browser for authentication. Tokens cached in ~/.mcp-gdrive/ or similar.

MCP Server Packages

Server	Package	Env Variable
todoist	`@abhiz123/todoist-mcp-server`	`TODOIST_API_TOKEN`
notion	`@notionhq/notion-mcp-server`	`NOTION_TOKEN`
ccg-bot	`@modelcontextprotocol/server-slack`	`SLACK_BOT_TOKEN`
astra-bot	`@modelcontextprotocol/server-slack`	`ASTRA_SLACK_BOT_TOKEN`
gdrive	`@isaacphi/mcp-gdrive`	`GOOGLE_OAUTH_CREDENTIALS` (path to OAuth keys)
gcal	`@anthropic/mcp-gcal`	`GCAL_OAUTH_PATH` (path to OAuth keys)
github	`@modelcontextprotocol/server-github`	`GITHUB_TOKEN`

Note: The gdrive package is @isaacphi/mcp-gdrive, NOT @anthropic/mcp-gdrive (that one doesn't exist on npm).

    "notion": {

Troubleshooting MCP

Error	Solution
"Failed to connect"	Check Node.js: `/opt/homebrew/bin/node --version`
401 Unauthorized	Tokens cached from old config. Fully restart VSCode
Package not found	Search npm: `/opt/homebrew/bin/npm search mcp <service>`
OAuth issues	Run manually: `GOOGLE_OAUTH_CREDENTIALS=<path> /opt/homebrew/bin/npx -y @isaacphi/mcp-gdrive`

Pre-install packages globally: /opt/homebrew/bin/npm install -g @isaacphi/mcp-gdrive @abhiz123/todoist-mcp-server

Todoist REST API Workaround

The Todoist MCP tool often returns 401 errors. Use the REST API directly via curl instead:

bash

# Create a task (source .env first to get TODOIST_API_TOKEN)
source /Users/terrytong/Documents/CCG/ToolProj/.env && curl -s -X POST "https://api.todoist.com/rest/v2/tasks" \
  -H "Authorization: Bearer $TODOIST_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Task title here",
    "project_id": "2363714490",
    "due_string": "today"
  }'

# Delete a task
source /Users/terrytong/Documents/CCG/ToolProj/.env && curl -s -X DELETE "https://api.todoist.com/rest/v2/tasks/{task_id}" \
  -H "Authorization: Bearer $TODOIST_API_TOKEN"

# Get tasks
source /Users/terrytong/Documents/CCG/ToolProj/.env && curl -s "https://api.todoist.com/rest/v2/tasks?project_id=2363714490" \
  -H "Authorization: Bearer $TODOIST_API_TOKEN"

Key: Always source .env before curl commands since MCP servers don't pick up bash exports.
