Create a new document (auto-lookup vault ID)
AI agents use create_document to create or update resources in Basecamp MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Basecamp MCP Server environment.
This tool creates new documents in Basecamp, which is a write operation that modifies the project state by adding new content. While reversible, misuse by an AI agent could create spam, confidential information leaks, or clutter in collaborative workspaces.
From the tool's definition Tool name 'create_document' and description 'Create a new document' explicitly indicates creation of new data. The action is reversible (documents can be archived/deleted), distinguishing it from destructive operations.
Documented attack patterns abuse exactly the kind of access create_document 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 create_document:
{
"version": "1",
"default": "deny",
"tools": {
"create_document": {
"limits": [
{
"counter": "create_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_document 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 document (auto-lookup vault ID). It is categorised as a Write tool in the Basecamp MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Basecamp MCP Server MCP server in PolicyLayer and add a rule for create_document: 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.
create_document 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_document 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_document. 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_document 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.
