Update or create analysis data for a specific file in the TreeSummary system
AI agents use update_file_analysis to create or update resources in ZMCPTools — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ZMCPTools environment.
This tool writes or modifies analysis data in the TreeSummary system, which is a reversible data modification operation. It does not execute arbitrary code, delete data permanently, or handle financial transactions. The severity is medium because unauthorized or malicious updates to file analysis data could corrupt development workflows, though the effects are reversible.
From the tool's definition Tool name 'update_file_analysis' with description 'Update or create analysis data for a specific file' indicates creation or modification of analysis metadata. The verb 'update' and 'create' are explicit indicators of write operations that modify system state.
Documented attack patterns abuse exactly the kind of access update_file_analysis gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ZMCPTools, and nothing reaches the server without passing your rules. This is the rule we recommend for update_file_analysis:
{
"version": "1",
"default": "deny",
"tools": {
"update_file_analysis": {
"limits": [
{
"counter": "update_file_analysis_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_file_analysis stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Update or create analysis data for a specific file in the TreeSummary system. It is categorised as a Write tool in the ZMCPTools MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ZMCPTools MCP server in PolicyLayer and add a rule for update_file_analysis: 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 ZMCPTools. Nothing to install.
update_file_analysis is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_file_analysis 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 update_file_analysis. 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.
update_file_analysis is provided by the ZMCPTools MCP server (zachhandley/zmcptools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
