MCP Server
The OpenCharts MCP server exposes your projects, templates, credits, and Theo tools to external IDEs and agents (Warp, Claude, Cursor, VS Code) over the Model Context Protocol.
In depth
Connect any MCP-compatible client with a personal API key (Bearer token) and the OpenCharts streamable-HTTP MCP endpoint. Tools include create_flowchart, ask_theo, project_list, template_list, credit_balance, and more — so external agents can drive your workspace.
Rate limits, scopes (read / write / ai), and revocable keys are managed from settings.
Examples
- Run create_flowchart from Warp
- Pipe a project list into a custom agent

API Key
An API key is the bearer token external clients use to authenticate against the OpenCharts MCP server — scoped, revocable, and tied to your account.
Tool Call
A tool call is a structured action Theo invokes during a response — like create_flowchart, send_email, or db_run_sql — that produces a real artifact or side effect, not just text.
