WHAT IT DOES

What add_memory does on Claude MCP Server Ecosystem

AI agents use add_memory to create or update resources in Claude MCP Server Ecosystem, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude MCP Server Ecosystem environment.

RISK

Why add_memory is rated Medium

This tool creates new records in persistent storage, which is reversible via update/delete operations. It is a Write operation—data modification without destructive or irreversible effects. Severity is medium because misuse could pollute memory storage with incorrect or sensitive data, but the impact is containable (records can be updated or removed).

From the tool's definition Tool name 'add_memory' with description 'Add a new memory to persistent storage' indicates data creation/modification to a persistent backend (likely PostgreSQL or Redis based on server description).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_memory safely

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

add_memory Rate-limited

add_memory 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.

How do I enforce a policy on add_memory? +

Register the Claude MCP Server Ecosystem MCP server in PolicyLayer and add a rule for add_memory: 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 Claude MCP Server Ecosystem. Nothing to install.

What risk level is add_memory? +

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

Can I rate-limit add_memory? +

Yes. Add a rate_limit block to the add_memory 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 add_memory completely? +

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