What count_text does on CoWork OS
AI agents call count_text to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why count_text is rated Low
This tool retrieves and measures textual properties without creating, modifying, deleting, or executing any operations. It is a straightforward read-only query function that returns metrics about provided text. The low severity reflects minimal risk even if misused by an agent, as it cannot affect system state or data integrity.
From the tool's definition Tool description states it 'Count[s] text length and basic units exactly (characters, words, lines, paragraphs, sentences)' — a pure analysis operation with no data modification, deletion, or side effects.

The rule that runs count_text safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For count_text, this is the rule to start with:
count_text is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every count_text call is checked against it from then on.

Register the CoWork OS MCP server in PolicyLayer and add a rule for count_text: 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 CoWork OS. Nothing to install.
count_text 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 count_text 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 count_text. 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.
count_text is provided by the CoWork OS MCP server (CoWork-OS/CoWork-OS). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
