# github_list_variables List repo Actions variables. Agent View of the PolicyLayer registry record for `github_list_variables`. HTML page: https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-variables ## Facts - Tool: `github_list_variables` - Server: Github (`dkeeno/github-mcp-server`) — https://policylayer.com/tools/dkeeno-github-mcp-server.md - Homepage: https://github.com/dkeeno/github-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "github_list_variables", "arguments": {} } } ``` ## Why github_list_variables is rated Low This tool retrieves metadata about repository Actions variables. It performs a read-only query with no capability to modify, delete, or execute code. The blast radius of misuse is minimal—an agent could only discover variable names and possibly their values (depending on API permissions), not alter system state or cause irreversible harm. This clearly fits the Read category. From the tool's own definition: "Tool name 'github_list_variables' and description 'List repo Actions variables' indicate a retrieval operation with no side effects." ## Use case AI agents call github_list_variables to retrieve information from Github without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Github: ```json { "version": "1", "default": "deny", "tools": { "github_list_variables": {} } } ``` ## Other tools on Github (68) - `github_delete_repo` — Destructive — https://policylayer.com/tools/dkeeno-github-mcp-server/github-delete-repo.md - `github_delete_secret` — Destructive — https://policylayer.com/tools/dkeeno-github-mcp-server/github-delete-secret.md - `github_remove_branch_protection` — Destructive — https://policylayer.com/tools/dkeeno-github-mcp-server/github-remove-branch-protection.md - `github_cancel_workflow_run` — Execute — https://policylayer.com/tools/dkeeno-github-mcp-server/github-cancel-workflow-run.md - `github_rerun_workflow` — Execute — https://policylayer.com/tools/dkeeno-github-mcp-server/github-rerun-workflow.md - `github_trigger_workflow` — Execute — https://policylayer.com/tools/dkeeno-github-mcp-server/github-trigger-workflow.md - `github_transfer_repo` — Financial — https://policylayer.com/tools/dkeeno-github-mcp-server/github-transfer-repo.md - `github_analyze_workflow_failure` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-analyze-workflow-failure.md - `github_audit_repo` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-audit-repo.md - `github_check_token_scopes` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-check-token-scopes.md - `github_get_branch_protection` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-branch-protection.md - `github_get_file` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-file.md - `github_get_issue` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-issue.md - `github_get_pr` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-pr.md - `github_get_profile_stats` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-profile-stats.md - `github_get_repo` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-repo.md - `github_get_repo_stats` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-repo-stats.md - `github_get_traffic` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-traffic.md - `github_get_user` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-user.md - `github_get_workflow_logs` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-workflow-logs.md - `github_get_workflow_run` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-get-workflow-run.md - `github_list_issues` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-issues.md - `github_list_prs` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-prs.md - `github_list_releases` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-releases.md - `github_list_repos` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-repos.md - `github_list_secrets` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-secrets.md - `github_list_security_alerts` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-security-alerts.md - `github_list_stargazers` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-stargazers.md - `github_list_workflow_runs` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-workflow-runs.md - `github_list_workflows` — Read — https://policylayer.com/tools/dkeeno-github-mcp-server/github-list-workflows.md - …and 38 more: https://policylayer.com/tools/dkeeno-github-mcp-server.md ## For agents This record is a snapshot.
