Count the words and characters in a string.
AI agents call word_count to retrieve information from Mdb Mcp Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only computation on a provided string. It retrieves or calculates information without modifying data, triggering external operations, or executing arbitrary code. The blast radius of misuse is minimal—a malicious agent could only waste computation on large strings or use word counts for trivial information gathering, neither of which poses meaningful risk.
From the tool's definition Tool name 'word_count' and description 'Count the words and characters in a string' indicate a pure analysis/querying function with no side effects, state changes, or external operations.
Attacks that exploit this kind of access
Count the words and characters in a string. It is categorised as a Read tool in the Mdb Mcp Gateway MCP Server, which means it retrieves data without modifying state.
Register the Mdb Mcp Gateway MCP server in PolicyLayer and add a rule for word_count: 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 Mdb Mcp Gateway. Nothing to install.
word_count 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 word_count 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 word_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.
word_count is provided by the Mdb Mcp Gateway MCP server (ranfysvalle02/m-gate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
