Retrieve detailed information about a specific board by ID. Use this when you need comprehensive details about a particular board.
AI agents call get_board to retrieve information from Trello without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation with no side effects. It fetches board details without creating, modifying, deleting, or executing external operations. The use of 'retrieve' and 'detailed information' confirms it is a read operation. Severity is low as unauthorized access to board metadata poses minimal direct harm compared to tools that can modify or delete data.
From the tool's definition Tool name 'get_board' and description 'Retrieve detailed information about a specific board by ID' indicate a read-only operation that queries data without modification.
Documented attack patterns abuse exactly the kind of access get_board gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trello, and nothing reaches the server without passing your rules. This is the rule we recommend for get_board:
{
"version": "1",
"default": "deny",
"tools": {
"get_board": {}
}
}get_board is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve detailed information about a specific board by ID. Use this when you need comprehensive details about a particular board. It is categorised as a Read tool in the Trello MCP Server, which means it retrieves data without modifying state.
Register the Trello MCP server in PolicyLayer and add a rule for get_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 Trello. Nothing to install.
get_board is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_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 get_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.
get_board is provided by the Trello MCP server (v4lheru/trello-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Trello, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
