github_read_file
AI agents call github_read_file to retrieve information from GitHub-Jira MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves file data from GitHub without side effects. Despite the empty description reducing confidence slightly, the explicit 'read' in the name and the pattern of sibling tools clearly establish this as a Read operation. Severity is low because retrieving repository files has minimal blast radius even if misused by an agent—it only accesses data the agent already has permission to read.
From the tool's definition Tool name 'github_read_file' indicates retrieval of file contents from GitHub repositories with no modification capability.
Attacks that exploit this kind of access
github_read_file. It is categorised as a Read tool in the GitHub-Jira MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub-Jira MCP Server MCP server in PolicyLayer and add a rule for github_read_file: 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 GitHub-Jira MCP Server. Nothing to install.
github_read_file 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 github_read_file 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 github_read_file. 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.
github_read_file is provided by the GitHub-Jira MCP Server MCP server (kronoswastaken/mcp-servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
