Tools
3| Parameter | Type | Required | Description |
|---|---|---|---|
| plan | string | No | Opaque plan from a previous result (widget use). A hint only: skips the solve when it still fits the source. |
| source | string | Yes | Mermaid source. Optional YAML frontmatter is honoured — set it in the source, never as arguments: `title`, and a nested `line9:` block with `theme` (one of `boardroom`, `linen`, `blueprint`), `scale: { node, spacing }` and `flowchart: { legend: on | off }`. The flowchart direction directive is also honoured. Maximum 100000 characters. |

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.
