THE RISK

Low Risk

Why runs needs a policy

This tool retrieves or queries analysis run data from DeepSource, consistent with a Read category operation. It has no side effects, does not execute code or commands, and does not modify or delete data. The filtering capability is a query parameter, not an execution or write operation. Severity is low as the blast radius of listing historical analysis runs is minimal.

From the tool's definition Tool name 'runs' with description 'List analysis runs for a DeepSource project with filtering' indicates a retrieval operation that queries and lists existing data without modifying or executing actions.

POLICY

How to control runs

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

policy.json

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

runs 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 DeepSource MCP Server — 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 runs

What does the runs tool do? +

List analysis runs for a DeepSource project with filtering. It is categorised as a Read tool in the DeepSource MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on runs? +

Register the DeepSource MCP Server MCP server in PolicyLayer and add a rule for runs: 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 DeepSource MCP Server. Nothing to install.

What risk level is runs? +

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

Can I rate-limit runs? +

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

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

runs is provided by the DeepSource MCP Server MCP server (sapientpants/deepsource-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 DeepSource MCP Server tool call.

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