# gitlab_list_branches List all branches in a project with protection status and last commit info. Agent View of the PolicyLayer registry record for `gitlab_list_branches`. HTML page: https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-branches ## Facts - Tool: `gitlab_list_branches` - Server: Gitlab (`dkeeno/gitlab-mcp-server`) — https://policylayer.com/tools/dkeeno-gitlab-mcp-server.md - Homepage: https://github.com/dkeeno/gitlab-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": "gitlab_list_branches", "arguments": {} } } ``` ## Why gitlab_list_branches is rated Low This tool performs a straightforward data retrieval operation—listing branches and their metadata. It has no side effects, does not execute code, does not modify state, and does not delete or move resources. The blast radius of misuse is minimal; an agent could at worst enumerate repository structure information that is typically already visible to authorized users. It cleanly fits the 'Read' category as defined. From the tool's own definition: "Tool name 'gitlab_list_branches' and description 'List all branches in a project with protection status and last commit info' indicate a read-only operation that retrieves and queries branch data without modifying or executing anything." ## Use case AI agents call gitlab_list_branches to retrieve information from Gitlab 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 Gitlab: ```json { "version": "1", "default": "deny", "tools": { "gitlab_list_branches": {} } } ``` ## Other tools on Gitlab (55) - `gitlab_delete_branch` — Destructive — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-delete-branch.md - `gitlab_delete_ci_variable` — Destructive — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-delete-ci-variable.md - `gitlab_delete_group_variable` — Destructive — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-delete-group-variable.md - `gitlab_revoke_group_access_token` — Destructive — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-revoke-group-access-token.md - `gitlab_revoke_personal_access_token` — Destructive — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-revoke-personal-access-token.md - `gitlab_revoke_project_access_token` — Destructive — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-revoke-project-access-token.md - `gitlab_cancel_pipeline` — Execute — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-cancel-pipeline.md - `gitlab_register_local_runner` — Execute — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-register-local-runner.md - `gitlab_retry_pipeline` — Execute — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-retry-pipeline.md - `gitlab_trigger_pipeline` — Execute — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-trigger-pipeline.md - `analyze_pipeline_failure` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/analyze-pipeline-failure.md - `gitlab_clone_repo` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-clone-repo.md - `gitlab_get_file` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-file.md - `gitlab_get_job_logs` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-job-logs.md - `gitlab_get_mr_diff` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-mr-diff.md - `gitlab_get_pipeline_artifacts` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-pipeline-artifacts.md - `gitlab_get_pipeline_jobs` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-pipeline-jobs.md - `gitlab_get_pipeline_status` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-pipeline-status.md - `gitlab_get_project` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-project.md - `gitlab_get_runner_status` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-runner-status.md - `gitlab_get_security_report` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-security-report.md - `gitlab_get_security_summary` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-get-security-summary.md - `gitlab_list_ci_variables` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-ci-variables.md - `gitlab_list_group_access_tokens` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-group-access-tokens.md - `gitlab_list_group_variables` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-group-variables.md - `gitlab_list_groups` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-groups.md - `gitlab_list_mrs` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-mrs.md - `gitlab_list_personal_access_tokens` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-personal-access-tokens.md - `gitlab_list_pipelines` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-pipelines.md - `gitlab_list_project_access_tokens` — Read — https://policylayer.com/tools/dkeeno-gitlab-mcp-server/gitlab-list-project-access-tokens.md - …and 25 more: https://policylayer.com/tools/dkeeno-gitlab-mcp-server.md ## For agents This record is a snapshot.
