generateToken · My Credentials MCP Server MCP: Risk & Policy

WHAT IT DOES

What generateToken does on My Credentials MCP Server

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

WHY IT NEEDS A POLICY

Why generateToken needs a policy

generateToken creates new cryptographic tokens used for authentication and session management. While token generation itself is not destructive, it modifies the security posture of applications by introducing new credentials. This falls under Write (creates new data/artifacts) rather than Read.

From the tool's definition Tool description: 'Generate various types of tokens (bearer, JWT secret, session, CSRF) for web applications and APIs.' The tool creates new tokens (bearer tokens, JWT secrets, session tokens, CSRF tokens) which are credentials that modify or extend…

Verdict

generateToken Rate-limited

generateToken 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.

FAQ

Questions about generateToken

What does the generateToken tool do? +

Generate various types of tokens (bearer, JWT secret, session, CSRF) for web applications and APIs. It is categorised as a Write tool in the My Credentials MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on generateToken? +

Register the My Credentials MCP Server MCP server in PolicyLayer and add a rule for generateToken: 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 My Credentials MCP Server. Nothing to install.

What risk level is generateToken? +

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

Can I rate-limit generateToken? +

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

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

generateToken is provided by the My Credentials MCP Server MCP server (preangelleo/my-credentials-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
