WHAT IT DOES

What session_create does on Mcp Anything

AI agents invoke session_create to trigger actions in Mcp Anything. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why session_create is rated High

Creating a persistent REPL (Read-Eval-Print Loop) session establishes an interactive execution environment tied to a CLI harness. This enables ongoing arbitrary command execution within the session context. While the creation itself is a setup action, its primary purpose is enabling code/command execution, making Execute the most appropriate category.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs session_create safely

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

session_create Rate-limited

session_create stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about session_create

What does the session_create tool do? +

Create a persistent REPL session for a CLI-Anything harness. It is categorised as a Execute tool in the Mcp Anything MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on session_create? +

Register the Mcp Anything MCP server in PolicyLayer and add a rule for session_create: 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 Mcp Anything. Nothing to install.

What risk level is session_create? +

session_create is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit session_create? +

Yes. Add a rate_limit block to the session_create 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_create completely? +

Set action: deny in the PolicyLayer policy for session_create. 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_create? +

session_create is provided by the Mcp Anything MCP server (Zaymadkid/mcp-anything). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
