AI agents call get_cards to retrieve information from Basecamp MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries card data from a card table without any side effects. It matches the 'Read' category definition: retrieves or queries data with no side effects (search, list, get, fetch). The blast radius of misuse is minimal since it only exposes existing data without the ability to modify, delete, or execute operations.
From the tool's definition Tool name 'get_cards' and description 'Get all cards from a card table' indicate a retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access get_cards gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Basecamp MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_cards:
{
"version": "1",
"default": "deny",
"tools": {
"get_cards": {}
}
}get_cards is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all cards from a card table. It is categorised as a Read tool in the Basecamp MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Basecamp MCP Server MCP server in PolicyLayer and add a rule for get_cards: 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 Basecamp MCP Server. Nothing to install.
get_cards 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_cards 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_cards. 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_cards is provided by the Basecamp MCP Server MCP server (qusaiisaleem/basecamp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Basecamp MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
