Set the active project context. All subsequent operations (save/search/list) will default to this project unless explicitly overridden. Like switching git branches - keeps you focused on one project at a time.
AI agents use set_active_project to create or update resources in Cognio — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cognio environment.
This tool changes configuration state (the active project) which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, move money, or retrieve information. The impact is scoped to context switching for subsequent operations, with low blast radius since the change is easily reversible by switching to a different project.
From the tool's definition Tool description states 'Set the active project context' and 'All subsequent operations...will default to this project', indicating it modifies state/context settings rather than reading or retrieving data.
Attacks that exploit this kind of access
Set the active project context. All subsequent operations (save/search/list) will default to this project unless explicitly overridden. Like switching git branches - keeps you focused on one project at a time. It is categorised as a Write tool in the Cognio MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cognio MCP server in PolicyLayer and add a rule for set_active_project: 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 Cognio. Nothing to install.
set_active_project 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 set_active_project 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 set_active_project. 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.
set_active_project is provided by the Cognio MCP server (0xrelogic/cognio). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
set_active_project is one line of Cognio's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
