Evolve is a system designed to help agents improve over time by learning from their trajectories. It uses a combination of an MCP server for tool integration, vector storage for memory, and LLM-based conflict resolution to refine its knowledge base.
Features
- MCP Server: Exposes tools to get guidelines and save trajectories.
- Conflict Resolution: Intelligently merges new insights with existing guidelines using LLMs.
- Trajectory Analysis: Automatically analyzes agent trajectories to generate guidelines and best practices.
- Milvus Integration: Uses Milvus (or Milvus Lite) for efficient vector storage and retrieval.
Architecture
Quick Start
Installation
Prerequisites:
- Python 3.12 or higher
uv (recommended) or pip
git clone <repository_url>
cd altk-evolve
uv venv --python=3.12 && source .venv/bin/activate
uv sync
Configuration
For direct OpenAI usage:
export OPENAI_API_KEY=sk-...
For LiteLLM proxy usage and model selection (including global fallback via EVOLVE_MODEL_NAME), see the configuration guide.
Running the MCP Server & UI
Evolve provides both a standard MCP server and a full Web UI (Dashboard & Entity Explorer).
[!IMPORTANT]
Building from Source: If you cloned this repository (rather than installing a pre-built package), you must build the UI before it can be served.
cd altk_evolve/frontend/ui
npm ci && npm run build
cd ../../../
See altk_evolve/frontend/ui/README.md for more frontend development details.
Starting Both Automatically
The easiest way to start both the MCP Server (on standard input/output) and the HTTP UI backend is to run the module directly:
uv run python -m evolve.frontend.mcp
This will start the UI server in the background on port 8000 and the MCP server in the foreground. You can then access the UI locally by opening your browser to:
http://127.0.0.1:8000/ui/
Starting the UI Standalone
If you only want to access the Web UI and API (without the MCP server stdio blocking the terminal), you can run the FastAPI application directly using uvicorn:
uv run uvicorn evolve.frontend.mcp.mcp_server:app --host 127.0.0.1 --port 8000
Then navigate to http://127.0.0.1:8000/ui/.
Starting only the MCP Server
If you're attaching Evolve to an MCP client that requires a direct command (like Claude Desktop):
uv run fastmcp run altk_evolve/frontend/mcp/mcp_server.py --transport stdio
Or for SSE transport:
uv run fastmcp run altk_evolve/frontend/mcp/mcp_server.py --transport sse --port 8201
Verify it's running:
npx @modelcontextprotocol/inspector@latest http://127.0.0.1:8201/sse --cli --method tools/list
Available tools:
get_entities(task: str, entity_type: str): Get relevant entities for a specific task, filtered by type (e.g., 'guideline', 'policy').get_guidelines(task: str): Get relevant guidelines for a specific task (backward compatibility alias).save_trajectory(trajectory_data: str, task_id: str | None): Save a conversation trajectory and generate new guidelines.create_entity(content: str, entity_type: str, metadata: str | None, enable_conflict_resolution: bool): Create a single entity in the namespace.delete_entity(entity_id: str): Delete a specific entity by its ID.
Tip Provenance
Evolve automatically tracks the origin of every guideline it generates or stores. Every tip entity contains metadata identifying its source:
creation_mode: Identifies how the tip was created (auto-phoenix via trace observability, auto-mcp via trajectory saving tools, or manual).source_task_id: The ID of the original trace or task that inspired the tip, providing full audibility.
See the Low-Code Tracing Guide for more details.
