count
Gets the number of documents in a collection
Part of the MongoDB MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call count to perform operations in MongoDB. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.
WHY ENFORCE A POLICY ON COUNT
Applying a policy to count gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.
RECOMMENDED POLICY
Apply a rate limit to control usage and monitor for unexpected behaviour.

FREQUENTLY ASKED QUESTIONS
What does the count tool do?
Gets the number of documents in a collection. It is categorised as a Other tool in the MongoDB MCP Server, which means it performs auxiliary operations.
How do I enforce a policy on count?
Add a rule in your Intercept YAML policy under the tools section for count. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the MongoDB MCP server.
What risk level is count?
count is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit count?
Yes. Add a rate_limit block to the count rule in your Intercept 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.
How do I block count completely?
Set action: deny in the Intercept policy for count. 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.
What MCP server provides count?
count is provided by the MongoDB MCP server (mongodb-js/mongodb-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
