MCP support
Provides a remote Streamable HTTP MCP server with OAuth 2.1 or Bearer API key authentication. It exposes tools, prompts, and resources for workspace content, agents, organization management, and related workflows.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

How to use Stable Baseline
Pick the surface that matches how you work. Every option talks to the same handlers, the same auth and the same data:
| Surface | What it's for | Install |
|---|---|---|
| MCP server | AI agents (Claude Code, Cursor, Windsurf, ChatGPT, Gemini, Smithery, …). Native protocol with prompts and resources. | Endpoint: api.stablebaseline.io/functions/v1/cloud-serve/mcp. See Quick start below. |
| REST API | Any HTTP client, Postman, OpenAPI codegen, Zapier-style integrators. Tool-RPC + idiomatic resource routes. | Live spec: /api/v1/openapi.json · Interactive docs: /api/v1/docs |
| TypeScript SDK | Node, browsers, Deno, Bun. Typed client.tools.<toolName>(...) surface. | npm i @stablebaseline/sdk, see packages/sdk-typescript |
CLI (sb) | Shells, scripts, CI/CD. sb tool call <name> --json '{...}'. | npm i -g @stablebaseline/cli, see packages/cli |
| Python SDK | Python apps, data work. Sync + async clients. | pip install stablebaseline, see packages/sdk-python |
222 tools across 20 categories. Same brain, same Knowledge Graph, same RBAC on every surface.
One workspace where humans and any MCP-compatible AI agent (Claude Code, Cursor, Windsurf, VS Code, Warp, OpenCode, Antigravity, OpenAI Codex, ChatGPT Developer Mode, Gemini CLI/Extensions and more) co-author living documents (Markdown-native with a rich superset on top), 40+ visual diagrams (Mermaid, BPMN 2.0, D2, PlantUML, GraphViz, cloud architecture, sequence, state, ERD, Gantt, freehand sketches), databases with views, forms and live dashboards, plans, timelines, tasks, improvements, the organisation's own agents, and a self-learning Knowledge Graph that IS the company brain.
Lean, fast, secure and affordable: flexible enough for one person organising a personal mind, through to small businesses, growing businesses and enterprise.
222 MCP tools across 20 categories let an agent drive end-to-end: sign-up → billing → org/workspace/project → members → teams → permissions → brain scope → docs → diagrams → whiteboards → plans → databases → agents, all without a human touching the UI.
Endpoint
https://api.stablebaseline.io/functions/v1/cloud-serve/mcp
Transport: Streamable HTTP (with SSE fallback)
Auth: OAuth 2.1 with Dynamic Client Registration, or Bearer API key (sta_*)
Discovery manifest: https://stablebaseline.io/.well-known/mcp.json
Quick start
Create an API key (skip OAuth)
- Sign up free, no credit card
- Open Organisation settings, Connected apps, Developers, then the API keys tab, and press Create Key. Choose what it may reach; databases start unticked, so tick them if your agent should use databases
- Copy the
sta_...key
(Or skip this: every client below also supports interactive OAuth on first call.)
Claude Desktop
Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"stable-baseline": {
"url": "https://api.stablebaseline.io/functions/v1/cloud-serve/mcp",
"headers": {
"Authorization": "Bearer sta_YOUR_KEY"
}
}
}
}
Or use the Claude Desktop OAuth flow: set just url and Claude will prompt you to authorise on first call.
Claude Code
claude mcp add --transport http stable-baseline \
https://api.stablebaseline.io/functions/v1/cloud-serve/mcp \
--header "Authorization: Bearer sta_YOUR_KEY"
Or via OAuth:
claude mcp add --transport http stable-baseline \
https://api.stablebaseline.io/functions/v1/cloud-serve/mcp
For skills that teach Claude Code the workflows (documents, diagrams, whiteboards, databases, dashboards and agents), install the Stable Baseline plugin for Claude Code.

Highlights
- End-to-end agent-managed: agents drive sign-up → billing → org/workspace/project lifecycle → members → teams → permissions → Knowledge Graph scope. No human touching the UI.
- Living documents: AI-native rich-text editor (CDMD = Markdown + inline diagrams, data tables, media, version history, real-time multi-author edits), with PDF and Word export.
- Visual diagram creation & editing: 40+ types, AI-generated, diagram-as-code, or freehand.
- Databases: tables of typed fields with views, row rules, forms and live dashboards. Import CSV or Excel, and get counts, totals and groups in one call.
- Agents: the organisation's own AI workers, each with a mandate, scoped access and approvals. Ask one or delegate a job from any MCP client, follow the run, decide its proposals, and undo a whole job.
- Plans, timelines, tasks, improvements & bugs: Day/Week/Month/Quarter/Year zoom Gantt, drag-to-reschedule, dependency cascades.
- Self-learning Knowledge Graph (Enterprise): auto-built from every doc, plan, improvement and database record; read by every connected agent. Stops hallucinations around gaps. Run one brain workspace-wide, one per department, or one per project, with RBAC end to end.
- Compliance Readiness (Enterprise): scans against OWASP ASVS, NIST SSDF, CIS Controls, ISO 27001, SOC 2, TISAX. Readiness only: not legal advice, not an attestation.
- Bring your own agent, no lock-in: any MCP-compatible client.
- Credit-cost preview ritual for every spending operation:
previewX→ confirm token →applyX.
Auth
| Method | When to use |
|---|---|
| OAuth 2.1 + Dynamic Client Registration | Default for desktop apps and IDE extensions. Smithery handles it automatically. |
Bearer API key (sta_...) | CI/CD, headless agents, server-to-server. Create one under Organisation settings, Connected apps, Developers (app.stablebaseline.io/settings/developers). Scope it to a workspace, project or folder, or let it reach the whole organisation. |
OAuth endpoints:

openid,profile,email,phone. These identify the signed-in user and do NOT decide what an agent may do: authorisation comes from the read/write/delete permissions per content type and the organisation capability toggles chosen on the consent screen. - Authoritative metadata (always prefer this over the list above):

Comments
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
