switch_project · mcp-Agentmemory MCP: Risk & Policy

WHAT IT DOES

What switch_project does on mcp-Agentmemory

AI agents use switch_project to create or update resources in mcp-Agentmemory — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your mcp-Agentmemory environment.

WHY IT NEEDS A POLICY

Why switch_project needs a policy

switch_project is a state-mutating operation that changes the active project context. While it doesn't directly create or delete data, it configures the destination for future memory operations. This is a Write-category action because it modifies system state in a reversible way (the project context can be switched back).

From the tool's definition Tool changes which project new memories are saved to, modifying the system state that determines where subsequent write operations are directed.

Verdict

switch_project Rate-limited

switch_project 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches mcp-Agentmemory, so you can run agents against it safely.

FAQ

Questions about switch_project

What does the switch_project tool do? +

Switch the active project context (affects which project new memories are saved to). It is categorised as a Write tool in the mcp-Agentmemory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on switch_project? +

Register the mcp-Agentmemory MCP server in PolicyLayer and add a rule for switch_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 mcp-Agentmemory. Nothing to install.

What risk level is switch_project? +

switch_project is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit switch_project? +

Yes. Add a rate_limit block to the switch_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.

How do I block switch_project completely? +

Set action: deny in the PolicyLayer policy for switch_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.

What MCP server provides switch_project? +

switch_project is provided by the mcp-Agentmemory MCP server (obidel/agentmemory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
