WHAT IT DOES

What session_begin does on Elementify MCP

AI agents call session_begin to retrieve information from Elementify MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why session_begin is rated Low

Even though session_begin only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs session_begin safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Elementify MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For session_begin, this is the rule to start with:

session_begin Allowed

session_begin is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "session_begin": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Elementify MCP, apply this rule, and every session_begin call is checked against it from then on.

FAQ

Questions about session_begin

What does the session_begin tool do? +

Begin a new change session. All writes made while this session is active are grouped together so they can be rolled back as a unit with session_restore. Use session_end to close the session normally. Sessions are stored server-side and capped at a bounded count (oldest ended/rolled-back sessions are evicted first). It is categorised as a Read tool in the Elementify MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on session_begin? +

Register the Elementify MCP server in PolicyLayer and add a rule for session_begin: 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 Elementify MCP. Nothing to install.

What risk level is session_begin? +

session_begin is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit session_begin? +

Yes. Add a rate_limit block to the session_begin 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.

How do I block session_begin completely? +

Set action: deny in the PolicyLayer policy for session_begin. 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.

What MCP server provides session_begin? +

session_begin is provided by the Elementify MCP server (vamerli/elementify-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
