Optional version string (only for versioned sites)
AI agents call version to retrieve information from MkDocs MCP Search Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply reads or returns a version string from the MkDocs site. It is a read-only operation that queries static version information with no ability to modify, execute, or delete data. The low severity reflects the minimal risk of information disclosure.
From the tool's definition Tool name is 'version' with description 'Optional version string (only for versioned sites)' — retrieves version metadata from documentation without side effects.
Documented attack patterns abuse exactly the kind of access version gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MkDocs MCP Search Server, and nothing reaches the server without passing your rules. This is the rule we recommend for version:
{
"version": "1",
"default": "deny",
"tools": {
"version": {}
}
}version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Optional version string (only for versioned sites). It is categorised as a Read tool in the MkDocs MCP Search Server MCP Server, which means it retrieves data without modifying state.
Register the MkDocs MCP Search Server MCP server in PolicyLayer and add a rule for version: 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 MkDocs MCP Search Server. Nothing to install.
version 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 version 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 version. 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.
version is provided by the MkDocs MCP Search Server MCP server (serverless-dna/mkdocs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MkDocs MCP Search 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.
