What add does on Cryptosense
AI agents use add to create or update resources in Cryptosense, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cryptosense environment.
Why add is rated Medium
The tool name 'add' suggests a Write operation that creates or modifies data reversibly. Without a description, confidence is reduced, but the sibling tools and server purpose (portfolio value tracking) indicate this creates or updates records rather than executing arbitrary code or deleting data. Classified as Write rather than Execute due to the straightforward nature of 'add' operations in financial contexts.
From the tool's definition Tool name 'add' with no description provided. In the context of a crypto/portfolio MCP server with sibling tools like 'add_expense' and portfolio management capabilities, 'add' likely creates or modifies data (e.g., adding to portfolio, expenses, or holdings).
Attacks that exploit this kind of access
The rule that runs add safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cryptosense, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add, this is the rule to start with:
add 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Cryptosense, apply this rule, and every add call is checked against it from then on.
Questions about add
add is a write tool on the Cryptosense MCP server. It is categorised as a Write tool in the Cryptosense MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Cryptosense MCP server in PolicyLayer and add a rule for add: 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 Cryptosense. Nothing to install.
add 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 add 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 add. 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.
add is provided by the Cryptosense MCP server (josephibra/cryptosense-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
