Create a new Miro board OR add frames to an existing board. This tool uses the Miro REST API to create boards with frames, sticky notes, text, and code blocks. It can create standalone boards or add content to existing boards.
AI agents use create_miro_board to create or update resources in Learning Hour MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Learning Hour MCP environment.
This tool creates new resources (Miro boards) and modifies existing ones by adding content, which are Write-category operations. The severity is medium because while Miro boards can be deleted (reversible deletion exists as a sibling tool), misuse could create numerous unwanted boards or spam content into existing boards, requiring manual cleanup.
From the tool's definition Tool description states it can 'Create a new Miro board OR add frames to an existing board' and 'create boards with frames, sticky notes, text, and code blocks.' The verbs 'create' and 'add' indicate reversible modification of data.
Documented attack patterns abuse exactly the kind of access create_miro_board gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Learning Hour MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_miro_board:
{
"version": "1",
"default": "deny",
"tools": {
"create_miro_board": {
"limits": [
{
"counter": "create_miro_board_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_miro_board stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new Miro board OR add frames to an existing board. This tool uses the Miro REST API to create boards with frames, sticky notes, text, and code blocks. It can create standalone boards or add content to existing boards. It is categorised as a Write tool in the Learning Hour MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Learning Hour MCP server in PolicyLayer and add a rule for create_miro_board: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Learning Hour MCP. Nothing to install.
create_miro_board is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_miro_board rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_miro_board. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_miro_board is provided by the Learning Hour MCP server (sdiamante13/learning-hour-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Learning Hour MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
