What secret-list does on Git
AI agents call secret-list to retrieve information from Git without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why secret-list is rated Low
This tool only retrieves metadata about secrets without exposing their actual values or modifying anything. It is a read-only operation with minimal security impact since the sensitive data itself is not returned. The explicit note that values are not exposed confirms this is safe reconnaissance rather than credential exposure.
From the tool's definition Tool description explicitly states 'Lists repository, organization, or environment secret names and metadata' and 'Secret values are not exposed by GitHub.' The verb 'Lists' indicates a retrieval operation without side effects.
Attacks that exploit this kind of access
The rule that runs secret-list safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Git, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For secret-list, this is the rule to start with:
secret-list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Git, apply this rule, and every secret-list call is checked against it from then on.
Questions about secret-list
Lists repository, organization, or environment secret names and metadata. Secret values are not exposed by GitHub. It is categorised as a Read tool in the Git MCP Server, which means it retrieves data without modifying state.
Register the Git MCP server in PolicyLayer and add a rule for secret-list: 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 Git. Nothing to install.
secret-list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the secret-list 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 secret-list. 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.
secret-list is provided by the Git MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
