# Project TODO List

This document outlines the tasks to be completed for the `mcp-bridge` project.

## Phase 1: Core Functionality

- [x] **Project Setup**
  - [x] Initialize Git repository and connect to remote
  - [x] Create directory structure (`/src`, `/test`, `/dist`)
  - [x] Create placeholder `build-test-deploy.sh` and `install.sh`
- [x] **Configuration Handling**
  - [x] Implement YAML parsing for `config.yaml`
  - [x] Implement loading of service-specific YAML files
  - [x] Finalize YAML structure (e.g., use a map for services, add `command` for adapter)
- [x] **HTTP Server**
  - [x] Create basic HTTP server that binds to `localhost`
  - [x] Implement configurable port via command-line flag
- [x] **MCP Adapter Management**
  - [x] Implement logic to spawn MCP adapters as child processes
  - [x] Manage the lifecycle of adapter processes (start, stop)
- [x] **MCP Communication**
  - [x] Implement `stdio`-based communication with child processes
  - [x] Implement JSON-RPC 2.0 message serialization/deserialization
- [x] **Request Routing**
  - [x] Implement handler to parse `?service=` query parameter
  - [x] Route incoming HTTP requests to the correct MCP service based on the query param
  - [x] Handle default service logic when the query param is omitted

## Phase 2: Features & Refinements

- [x] **Endpoint Mapping**
  - [x] Map HTTP POST requests to the `tools/call` MCP method
  - [x] Pass request body as parameters to the MCP call
- [x] **Error Handling**
  - [x] Translate MCP errors to appropriate HTTP status codes (400, 500)
  - [x] Implement graceful handling for config errors, missing services, etc.
- [ ] **Logging**
  - [ ] Add structured logging for requests, responses, and errors
  - [ ] Implement configurable verbosity via a command-line flag (e.g., `-v`)
- [ ] **Configuration Reload**
  - [ ] Implement dynamic config reload via `SIGHUP` signal
  - [ ] Implement `/reload` HTTP endpoint
  - [ ] Define and implement session/process behavior on reload

## Phase 3: Testing & Distribution

- [ ] **Build & Installation Scripts**
  - [ ] Populate `build-test-deploy.sh` to compile for multiple architectures (macOS, Linux, Windows) and place binaries in `./dist`
  - [ ] Populate `install.sh` to download and install the correct binary for the user's system
- [ ] **Testing**
  - [ ] Create basic unit tests for HTTP handling and request routing in `/test`
  - [ ] Create integration tests for MCP communication
- [ ] **Documentation**
  - [ ] Create `README.md` with comprehensive installation, configuration, and usage instructions
  - [ ] Provide sample `config.yaml` and `service1.yaml` files
- [ ] **Finalization**
  - [ ] Commit compiled binaries to the `./dist` directory
  - [ ] Tag a version `v1.0.0`
