Evolve: On‑the‑job learning for AI agents

Blog posts: IBM announcement | Hugging Face blog

Coding agents repeat the same mistakes because they start fresh every session. Evolve gives agents memory — they learn from what worked and what didn't, so each session is better than the last.

Evolve is a system designed to help agents improve over time by learning from their trajectories. The Lite version is designed to effortlessly slot into existing agent assistants like Claude Code and Codex. 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.

On the AppWorld benchmark, Evolve improved agent reliability by +8.9 points overall, with a 74% relative increase on hard multi-step tasks.

Quick Start (Evolve MCP Server)

Installation

Prerequisites:

• Python 3.12 or higher
• uv (recommended) or pip

From Source

# Clone the repository and install dependencies
git clone https://github.com/agenttoolkit/altk-evolve.git
cd altk-evolve
uv venv --python=3.12 && source .venv/bin/activate
uv sync
# Build the UI
cd frontend/ui
npm ci && npm run build
cd ../..

From PyPI

pip install altk-evolve

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 Services

Start the Web UI and MCP server

uv run evolve-mcp

The Web UI can be accessed from: http://127.0.0.1:8000/ui/

Starting the Web UI and MCP Server

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 altk_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 evolve-mcp

Or for SSE transport:

uv run evolve-mcp --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.

Features

• Proactive: Learns how to recognize problems and their solutions, and generates guidelines that get automatically applied to new tasks.
• Conflict Resolution: Update existing guidelines when new information contradicts them.
• On Command: An array of tools to manage guidelines whether in the agent or through a CLI

Architecture

Evolve is built on a modular architecture which forms a feedback loop, taking conversation traces (trajectories) from an agent, extracting key insights into a database, feeding it back into the agent.

Lite Mode omits the Interaction layer. All activity is performed in-agent

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.
