Flowboard MCP

An AI-native architecture whiteboard that allows agents to create, inspect, validate, patch, and review cloud architecture diagrams using a structured model accessible via REST or MCP. It supports diagram round-tripping in Markdown, JSON, or YAML, and enables agents to discover shapes, manage boards, and submit feedback.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

While using Flowboard, proactively call submit_agent_feedback when you encounter confusing behavior, a layout or validation problem, a workaround, or an improvement idea. Before finishing an editing task, submit one concise report if you observed actionable friction; avoid duplicate reports and do not submit empty praise. Include the diagram id when relevant, tool_name, a factual observation, a suggested improvement, and the outcome of any workaround. Write a brief user-facing summary, not private internal reasoning, credentials, or unrelated conversation content. Reports are saved separately from diagrams for later product review. Use list_agent_feedback to review your previous reports. Reports are automatically stamped with the running build version and commit. Reviews default to the current build; use build=* to review historical reports. Failed authenticated MCP tool calls are automatically saved; use list_agent_errors to review common submission errors.

Advertised by the server during the last successful anonymous check.

Discover every Flowboard node shape before drawing. Search all core, AWS, and Google Cloud shapes by type, label, detail, provider, or category. Results return the exact node type and icon path and are paginated; call again with next_offset. This public tool requires no API key.

create_diagram

Advertised by the server during the last successful anonymous check.

Create one persistent Flowboard architecture diagram after calling list_shapes and list_diagrams, then reuse its ID with patch_diagram or update_diagram instead of making test copies. Any node may contain any other node; indentation expresses grouping, not infrastructure policy. Markdown nodes look like '- API {#api type=pod x=100 y=100}'. Flows belong under ## Flows. JSON and YAML use flows[]. A node may use icon=github independently of type. See https://flowboard.studio/guide#agent-workflow

patch_diagram

Advertised by the server during the last successful anonymous check.

Safely edit an existing diagram without replacing the full document. Operations run as one atomic saved update. Supported ops: set_title, auto_layout, add/update/delete_node, add/update/delete_flow, and add/update/delete_note. update operations use id plus a changes object. Deletes refuse nodes that still have children or flows.

validate_diagram

Advertised by the server during the last successful anonymous check.

Check broken flows, missing/cyclic parents, children outside parent bounds, overlapping sibling or top-level nodes, pipelines crossing unrelated resources, orphaned nodes, and optional company policy rules. Layout findings include exact coordinates and a patch_diagram-compatible suggested_fix so an agent can correct placement without asking a person which direction to move something. Rerun validation after applying fixes. Returns findings without changing the diagram; mutation responses include findings and computed_bounds.

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http flowboard-mcp https://flowboard.studio/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
