THE RISK

Low Risk

Why authenticate needs a policy

The tool authenticates using already-stored tokens (no credential creation) and fetches/retrieves project and tag data. The primary side effect is reading data. While authentication could be considered a session Write, the description emphasizes fetching data and using stored tokens rather than creating new credentials. Severity is low as misuse would only expose project/tag metadata.

From the tool's definition Authenticate with stored tokens and fetch project and tag data

POLICY

How to control authenticate

PolicyLayer is an MCP gateway — it sits between your AI agents and Dida, and nothing reaches the server without passing your rules. This is the rule we recommend for authenticate:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "authenticate": {}
  }
}

authenticate is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Dida — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about authenticate

What does the authenticate tool do? +

Authenticate with stored tokens and fetch project and tag data. It is categorised as a Read tool in the Dida MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on authenticate? +

Register the Dida MCP server in PolicyLayer and add a rule for authenticate: 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 Dida. Nothing to install.

What risk level is authenticate? +

authenticate is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit authenticate? +

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

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

authenticate is provided by the Dida MCP server (zhongwencool/dida-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Dida tool call.

Start from Dida, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
