创建一个新的GraphMemory存储块，用于表示图结构数据。支持tree（树结构）和graph（图结构）两种模式，适用于知识图谱、关系网络等场景。
AI agents use addGraphMemory to create or update resources in ThinkMem — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ThinkMem environment.
This tool creates new memory structures that can be modified or deleted later (as evidenced by sibling tools like deleteMemory and deleteListElement). Creating a new graph memory block is a Write operation—it modifies the system state reversibly.
From the tool's definition Tool creates a new GraphMemory storage block ("创建一个新的GraphMemory存储块"), which is a reversible data creation/modification operation. The description indicates it writes graph structure data for knowledge graphs and relationship networks.
Documented attack patterns abuse exactly the kind of access addGraphMemory gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ThinkMem, and nothing reaches the server without passing your rules. This is the rule we recommend for addGraphMemory:
{
"version": "1",
"default": "deny",
"tools": {
"addGraphMemory": {
"limits": [
{
"counter": "addgraphmemory_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}addGraphMemory 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.

Register the ThinkMem MCP server in PolicyLayer and add a rule for addGraphMemory: 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 ThinkMem. Nothing to install.
addGraphMemory 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 addGraphMemory 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 addGraphMemory. 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.
addGraphMemory is provided by the ThinkMem MCP server (rickonono3/thinkmem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ThinkMem, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
