Analyze text and return word count, character count, and reading time.
AI agents call analyze_text to retrieve information from Demo 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 and computes statistics from provided text without creating, modifying, deleting, or executing any operations. It is a pure read operation that extracts information, fitting the Read category definition of retrieving or querying data with no side effects.
From the tool's definition The tool 'analyze_text' performs text analysis to return word count, character count, and reading time. These are read-only metrics computed from input text with no side effects, modifications, or external operations.
Documented attack patterns abuse exactly the kind of access analyze_text gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Demo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_text:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_text": {}
}
}analyze_text 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.
Analyze text and return word count, character count, and reading time. It is categorised as a Read tool in the Demo MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Demo MCP Server MCP server in PolicyLayer and add a rule for analyze_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 Demo MCP Server. Nothing to install.
analyze_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 analyze_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 analyze_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.
analyze_text is provided by the Demo MCP Server MCP server (thechandanbhagat/mcp-demo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Demo 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.
