Stable Baseline

What is Stable Baseline?

Stable Baseline is a cloud-hosted MCP server that acts as an end-to-end agent-managed company brain. It integrates with any MCP-compatible AI agent (Claude Code, Cursor, Windsurf, ChatGPT, Gemini, etc.) and offers 193 tools across 18 categories for documents, diagrams, plans, knowledge graphs, billing, and more. It is designed for individuals, teams, and enterprises who want a single workspace where humans and AI co-author living content.

How to use Stable Baseline?

Pick a surface that matches your workflow: the MCP server endpoint (https://api.stablebaseline.io/functions/v1/cloud-serve/mcp), REST API, TypeScript SDK (npm i @stablebaseline/sdk), Python SDK (pip install stablebaseline), or CLI (npm i -g @stablebaseline/cli). Quick start: sign up free at app.stablebaseline.io, generate an API key (starts with sta_), and configure your client with the endpoint and bearer token, or use OAuth 2.1 for interactive flows. Configuration examples are provided for Claude Desktop, Claude Code, Cursor, Windsurf, and VS Code.
