Phase 2: Detect Services
Check for service integrations:
Service
Detection
Sentry
sentry-sdk in deps, @sentry/* packages, .sentryclirc, sentry.properties
Linear
Linear config files, .linear/ directory
Read dependency files to identify frameworks:
package.json→ checkdependenciesanddevDependencies
pyproject.toml→ check[project.dependencies]or[tool.poetry.dependencies]
Gemfile→ check gem names
Cargo.toml→ check[dependencies]
Phase 3: Check Existing Settings
cat .claude/settings.json 2>/dev/null || echo "No existing settings"
Phase 4: Generate Recommendations
Build the allow list by combining:

MCP Server Suggestions
MCP servers are configured in .mcp.json (not settings.json). Check for existing config:
cat .mcp.json 2>/dev/null || echo "No existing .mcp.json"
#### Sentry MCP (if Sentry SDK detected)
Add to .mcp.json (replace {org-slug} and {project-slug} with your Sentry organization and project slugs):
{
"mcpServers": {
"sentry": {
"type": "http",
"url": "https://mcp.sentry.dev/mcp/{org-slug}/{project-slug}"
}
}
}
#### Linear MCP (if Linear usage detected)
Add to .mcp.json:
{
"mcpServers": {
"linear": {
"command": "npx",
"args": ["-y", "@linear/mcp-server"],
"env": {
"LINEAR_API_KEY": "${LINEAR_API_KEY}"
}
}
}
}
Note: Never suggest GitHub MCP. Always use gh CLI commands for GitHub.
Output Format
Present your findings as:
- Summary Table - What was detected
- Recommended settings.json - Complete JSON ready to copy
- MCP Suggestions - If applicable
- Merge Instructions - If existing settings found
Example output structure:
## Detected Tech Stack
| Category | Found |
| --------------- | -------------- |
| Languages | Python 3.x |
| Package Manager | poetry |
| Frameworks | Django, Celery |
| Services | Sentry |
| Build Tools | Docker, Make |
## Recommended .claude/settings.json
\`\`\`json
{
"permissions": {
"allow": [
// ... grouped by category with comments
],
"deny": []
}
}
\`\`\`
## Recommended .mcp.json (if applicable)
If you use Sentry or Linear, add the MCP config to `.mcp.json`...
Important Rules
What to Include
- Only READ-ONLY commands that cannot modify state
- Only tools that are actually used by the project (detected via lock files)
- Standard system commands (ls, cat, find, etc.)
- The
:*suffix allows any arguments to the base command
What to NEVER Include
- Absolute paths - Never include user-specific paths like
/home/user/scripts/fooor/Users/name/bin/bar
- Custom scripts - Never include project scripts that may have side effects (e.g.,
./scripts/deploy.sh)
- Alternative package managers - If the project uses pnpm, do NOT include npm/yarn commands
- Commands that modify state - No install, build, run, write, or delete commands
Package Manager Rules
Only include the package manager actually used by the project:
If Detected
Include
Do NOT Include
pnpm-lock.yaml
pnpm commands
npm, yarn
yarn.lock
yarn commands
npm, pnpm
package-lock.json
npm commands
yarn, pnpm
poetry.lock

pip (unless also has requirements.txt)
uv.lock

Pipfile.lock

If multiple lock files exist, include only the commands for each detected manager.
