Code Review
This pull request changes the Forgetful MCP server from HTTP to stdio transport. However, this change directly contradicts the project's documentation and installation scripts, which explicitly warn that stdio transport is broken due to an upstream bug and that HTTP transport must be used. This change is likely to cause a regression and break the Forgetful integration. The configuration should be reverted unless the underlying bug has been fixed and all related documentation is updated accordingly.

Pull request overview
This PR changes the Forgetful MCP server configuration from HTTP transport (localhost:8020/mcp) to stdio transport using the uvx forgetful-ai command. However, this change contradicts extensive project documentation stating that Forgetful's stdio transport is broken due to FastMCP banner corruption (upstream issue #19), with no explanation or evidence that this issue has been resolved.
Key Changes:
- Modified
.mcp.jsonto use stdio transport with uvx command instead of HTTP transport - Removed HTTP URL configuration for Forgetful server
- Added uvx command-based invocation for automatic package installation
Upstream issue #19 (ScottRBK/forgetful#19) has been fixed. Forgetful now works correctly with stdio transport. Changes: - Remove HTTP-based install scripts (Linux/Windows) - Remove HTTP health check script - Update CONTRIBUTING.md to document stdio setup - Update CLAUDE.md to reflect stdio transport - Simplify configuration (uvx handles lifecycle automatically) Related: PR #768 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Changes SummaryThis PR migrates the Forgetful MCP server from HTTP transport to stdio transport with automatic uvx installation. This simplifies the setup by eliminating the need for manual systemd/scheduled task services, making Forgetful automatically start on demand like other MCP servers. The change removes complex installation scripts and documentation for HTTP-based service management. Type: refactoring Components Affected: MCP Configuration, Forgetful MCP Server Setup, Documentation, Installation Scripts, Slash Commands Files Changed
Architecture Impact
Risk Areas: Users with existing Forgetful HTTP services will need to stop and disable them, Changes to .mcp.json affect MCP server connectivity - runtime failure if uvx not installed, Removed installation/health check scripts may have been in use by existing workflows, Documentation changes may not reach all users who rely on HTTP setup Suggestions

🟡 MEDIUM - Piping Invoke-WebRequest output directly to Invoke-Expression
Agent: security
Category: security
Description:
The Windows installation instructions use irm ... | iex (Invoke-RestMethod piped to Invoke-Expression), which executes arbitrary code from the internet with -ExecutionPolicy ByPass. While this is standard uv installer documentation, it poses a supply chain risk.
Suggestion:
Recommend a two-step process: (1) Download the script: Invoke-WebRequest -Uri 'https://astral.sh/uv/install.ps1' -OutFile 'install.ps1', (2) Review the script, (3) Execute with appropriate execution policy. Consider recommending winget or scoop package managers as safer alternatives.

🟠 HIGH - MCP server uses uvx to execute arbitrary packages without pinning
Agent: security
Category: security
Description:
The Forgetful MCP server configuration uses uvx forgetful-ai without pinning to a specific version. This means every time the MCP server starts, it could download and execute a different version. Compare to serena which is pinned to a git repository.
Suggestion:
Pin to a specific version: "args": ["forgetful-ai==X.Y.Z"] where X.Y.Z is a known good version, or use --from git+https://github.com/ScottRBK/forgetful@<commit-sha> to pin to a specific commit like the Serena configuration does.
