Retrieve the contents of a specific sequential thinking session file
AI agents call getsession to retrieve information from Sequential Thinking 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 or queries session data without modifying, deleting, or executing operations. The verb 'Retrieve' and the passive scope (reading existing session files) place it squarely in the Read category. Severity is low because exposure is limited to information disclosure of session contents, with no blast radius for destructive or financial operations.
From the tool's definition Tool name 'getsession' and description 'Retrieve the contents of a specific sequential thinking session file' indicate data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access getsession gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sequential Thinking MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getsession:
{
"version": "1",
"default": "deny",
"tools": {
"getsession": {}
}
}getsession is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve the contents of a specific sequential thinking session file. It is categorised as a Read tool in the Sequential Thinking MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sequential Thinking MCP Server MCP server in PolicyLayer and add a rule for getsession: 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 Sequential Thinking MCP Server. Nothing to install.
getsession 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 getsession 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 getsession. 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.
getsession is provided by the Sequential Thinking MCP Server MCP server (recallnet/sequential-thinking-recall). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sequential Thinking MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
