AI agents use export_session to create or update resources in Guru Pk — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Guru Pk environment.
This tool exports session data into a Markdown file, which is a reversible write operation that creates new data artifacts without destroying existing data. It does not read-only (data is transformed/formatted), does not execute arbitrary code, does not delete data, and has no financial impact.
From the tool's definition Tool name 'export_session' combined with description '导出会话记录为Markdown文件' (export session record as Markdown file) indicates the tool creates and writes a file output. The verb '导出' (export) means to output/save data to a new file artifact.
Documented attack patterns abuse exactly the kind of access export_session gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Guru Pk, and nothing reaches the server without passing your rules. This is the rule we recommend for export_session:
{
"version": "1",
"default": "deny",
"tools": {
"export_session": {
"limits": [
{
"counter": "export_session_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}export_session 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.
Free to start. No card required.
导出会话记录为Markdown文件. It is categorised as a Write tool in the Guru Pk MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Guru Pk MCP server in PolicyLayer and add a rule for export_session: 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 Guru Pk. Nothing to install.
export_session 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 export_session 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 export_session. 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.
export_session is provided by the Guru Pk MCP server (mitsudoai/guru-pk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Guru Pk, 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.
