Integrate feedback-o-tron: Needs Elixir MCP setup (complex integration)

[hyperpolymath]

Overview

This issue tracks the integration work needed to set up the Elixir MCP (Model Context Protocol) server for feedback-o-tron.

Current State

• Elixir MCP directory structure exists at elixir-mcp/
• Integration work required to connect the MCP server with the feedback system

Tasks

• Complete Elixir MCP server implementation
• Configure MCP protocol handlers
• Set up communication between feedback-o-tron and MCP clients
• Add appropriate error handling and logging
• Write integration tests
• Update documentation for MCP setup

Complexity Note

This is marked as a complex integration requiring careful attention to:

• Protocol compliance
• Elixir/BEAM ecosystem patterns
• Error handling across process boundaries
• Performance considerations

Related

See elixir-mcp/ directory for initial implementation.

Update: Reusable MCP Library Created

I've created a standalone, reusable MCP server framework that feedback-o-tron (and other hyperpolymath Elixir projects) can use:

Repository: https://github.com/hyperpolymath/elixir-mcp-server

What It Provides

• Complete JSON-RPC 2.0 protocol implementation
• stdio transport (MCP standard)
• Tool behavior and registration system
• OTP supervision for reliability
• Type-safe tool definitions

Next Steps for feedback-o-tron Integration

1. Add {:elixir_mcp_server, "~> 0.1.0"} to deps
2. Define feedback submission tools using ElixirMcpServer.Tool behavior
3. Start MCP server alongside feedback-o-tron application
4. Configure in Claude Code's .claude.json

This makes the integration much simpler and provides a proven, reusable foundation.

[hyperpolymath]

I can take this. To proceed, please confirm:

1. Which MCP transport you want (stdio vs. HTTP) for the Elixir server.
2. The target protocol version / spec you want to implement.
3. Any required auth or sandboxing rules.
4. Whether elixir-mcp/ should be a standalone app or integrated into the main umbrella.

Once confirmed, I’ll wire the handlers, add logging/error handling, and add minimal integration tests + docs.

Integrated elixir-mcp-server into elixir-mcp:

• Added {:elixir_mcp_server, "~> 0.1.0"} dependency
• Start MCP server when FEEDBACK_A_TRON_MCP=1 or --mcp-server is set
• submit_feedback tool now uses ElixirMcpServer.Tool and returns MCP text content
• README updated with MCP enablement note
