Get the complete history for a specific file
AI agents call get_file_history to retrieve information from Local History 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 historical version metadata and content for a file without creating, modifying, deleting, or executing anything. It is a straightforward read/query operation with no side effects. The local history context means the data is already captured on the user's machine, so exposure is limited to what would already be visible through the IDE.
From the tool's definition Tool name is 'get_file_history' and description states 'Get the complete history for a specific file'. This is a retrieval operation that queries historical snapshots without modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and Local History MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_file_history:
{
"version": "1",
"default": "deny",
"tools": {
"get_file_history": {}
}
}get_file_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the complete history for a specific file. It is categorised as a Read tool in the Local History MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Local History MCP Server MCP server in PolicyLayer and add a rule for get_file_history: 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 Local History MCP Server. Nothing to install.
get_file_history 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 get_file_history 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 get_file_history. 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.
get_file_history is provided by the Local History MCP Server MCP server (xxczaki/local-history-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Local History MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
