7f987737f9 refactor(core): add LLMClient facade trait; decouple TUI from Provider/MCP details 2025-10-17 01:52:10 +02:00
690f5c7056 feat(cli): add MCP management subcommand with add/list/remove commands
Introduce `McpCommand` enum and handlers in `owlen-cli` to manage MCP server registrations, including adding, listing, and removing servers across configuration scopes. Add scoped configuration support (`ScopedMcpServer`, `McpConfigScope`) and OAuth token handling in core config, alongside runtime refresh of MCP servers. Implement toast notifications in the TUI (`render_toasts`, `Toast`, `ToastLevel`) and integrate async handling for session events. Update config loading, validation, and schema versioning to accommodate new MCP scopes and resources. Add `httpmock` as a dev dependency for testing.

7851af14a9 refactor(core): remove provider module, migrate to LLMProvider, add client mode handling, improve serialization error handling, update workspace edition, and clean up conditionals and imports 2025-10-12 12:38:55 +02:00
952e4819fe refactor(core)!: rename Provider to LLMProvider and update implementations
- Export `LLMProvider` from `owlen-core` and replace public `Provider` re-exports.
- Convert `OllamaProvider` to implement the new `LLMProvider` trait with associated future types.
- Adjust imports and trait bounds in `remote_client.rs` to use the updated types.
- Add comprehensive provider interface tests (`provider_interface.rs`) verifying router routing and provider registry model listing with `MockProvider`.
- Align dependency versions across workspace crates by switching to workspace-managed versions.
- Extend CI (`.woodpecker.yml`) with a dedicated test step and generate coverage reports.
- Update architecture documentation to reflect the new provider abstraction.

7534c9ef8d feat(phase10): complete MCP-only architecture migration
Phase 10 "Cleanup & Production Polish" is now complete. All LLM
interactions now go through the Model Context Protocol (MCP), removing
direct provider dependencies from CLI/TUI.

## Major Changes

### MCP Architecture
- All providers (local and cloud Ollama) now use RemoteMcpClient
- Removed owlen-ollama dependency from owlen-tui
- MCP LLM server accepts OLLAMA_URL environment variable for cloud providers
- Proper notification handling for streaming responses
- Fixed response deserialization (McpToolResponse unwrapping)

### Code Cleanup
- Removed direct OllamaProvider instantiation from TUI
- Updated collect_models_from_all_providers() to use MCP for all providers
- Updated switch_provider() to use MCP with environment configuration
- Removed unused general config variable

### Documentation
- Added comprehensive MCP Architecture section to docs/architecture.md
- Documented MCP communication flow and cloud provider support
- Updated crate breakdown to reflect MCP servers

### Security & Performance
- Path traversal protection verified for all resource operations
- Process isolation via separate MCP server processes
- Tool permissions controlled via consent manager
- Clean release build of entire workspace verified

## Benefits of MCP Architecture

1. **Separation of Concerns**: TUI/CLI never directly instantiates providers
2. **Process Isolation**: LLM interactions run in separate processes
3. **Extensibility**: New providers can be added as MCP servers
4. **Multi-Transport**: Supports STDIO, HTTP, and WebSocket
5. **Tool Integration**: MCP servers expose tools to LLMs

This completes Phase 10 and establishes a clean, production-ready architecture
for future development.

cdf95002fc feat(phase9): implement WebSocket transport and failover system
Implements Phase 9: Remoting / Cloud Hybrid Deployment with complete
WebSocket transport support and comprehensive failover mechanisms.

**WebSocket Transport (remote_client.rs):**
- Added WebSocket support to RemoteMcpClient using tokio-tungstenite
- Full bidirectional JSON-RPC communication over WebSocket
- Connection establishment with error handling
- Text/binary message support with proper encoding
- Connection closure detection and error reporting

**Failover & Redundancy (failover.rs - 323 lines):**
- ServerHealth tracking: Healthy, Degraded, Down states
- ServerEntry with priority-based selection (lower = higher priority)
- FailoverMcpClient implementing McpClient trait
- Automatic retry with exponential backoff
- Circuit breaker pattern (5 consecutive failures triggers Down state)
- Background health checking with configurable intervals
- Graceful failover through server priority list

**Configuration:**
- FailoverConfig with tunable parameters:
  - max_retries: 3 (default)
  - base_retry_delay: 100ms with exponential backoff
  - health_check_interval: 30s
  - circuit_breaker_threshold: 5 failures

**Testing (phase9_remoting.rs - 9 tests, all passing):**
- Priority-based server selection
- Automatic failover to backup servers
- Retry mechanism with exponential backoff
- Health status tracking and transitions
- Background health checking
- Circuit breaker behavior
- Error handling for edge cases

**Dependencies:**
- tokio-tungstenite 0.21
- tungstenite 0.21

All tests pass successfully. Phase 9 specification fully implemented.

33d11ae223 fix(agent): improve ReAct parser and tool schemas for better LLM compatibility
- Fix ACTION_INPUT regex to properly capture multiline JSON responses
  - Changed from stopping at first newline to capturing all remaining text
  - Resolves parsing errors when LLM generates formatted JSON with line breaks

- Enhance tool schemas with detailed descriptions and parameter specifications
  - Add comprehensive Message schema for generate_text tool
  - Clarify distinction between resources/get (file read) and resources/list (directory listing)
  - Include clear usage guidance in tool descriptions

- Set default model to llama3.2:latest instead of invalid "ollama"

- Add parse error debugging to help troubleshoot LLM response issues

The agent infrastructure now correctly handles multiline tool arguments and
provides better guidance to LLMs through improved tool schemas. Remaining
errors are due to LLM quality (model making poor tool choices or generating
malformed responses), not infrastructure bugs.

05e90d3e2b feat(mcp): add LLM server crate and remote client integration
- Introduce `owlen-mcp-llm-server` crate with RPC handling, `generate_text` tool, model listing, and streaming notifications.
- Add `RpcNotification` struct and `MODELS_LIST` method to the MCP protocol.
- Update `owlen-core` to depend on `tokio-stream`.
- Adjust Ollama provider to omit empty `tools` field for compatibility.
- Enhance `RemoteMcpClient` to locate the renamed server binary, handle resource tools locally, and implement the `Provider` trait (model listing, chat, streaming, health check).
- Add new crate to workspace `Cargo.toml`.
