# fetch_branches A read tool on the Storyblok MCP Server MCP server. Agent View of the PolicyLayer registry record for `fetch_branches`. HTML page: https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-branches ## Facts - Tool: `fetch_branches` - Server: Storyblok MCP Server (`arjuncodess/storyblok-mcp`) — https://policylayer.com/tools/arjuncodess-storyblok-mcp.md - Homepage: https://github.com/ArjunCodess/storyblok-mcp - 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": "fetch_branches", "arguments": {} } } ``` ## Why fetch_branches is rated Low The tool retrieves branch information from Storyblok CMS. The 'fetch' operation indicates data retrieval without modification or execution. Although the description is empty, the naming pattern is consistent with other Read operations in the sibling tool list (e.g., 'compare_branches' suggests branches are read-only query subjects). The blast radius of retrieving branch metadata is minimal. From the tool's own definition: "Tool name 'fetch_branches' uses the 'fetch' verb, which is explicitly listed in the Read category rules as a retrieval operation that produces no side effects." ## Use case AI agents call fetch_branches to retrieve information from Storyblok MCP Server 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 Storyblok MCP Server: ```json { "version": "1", "default": "deny", "tools": { "fetch_branches": {} } } ``` ## Other tools on Storyblok MCP Server (114) - `delete_access_token` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-access-token.md - `delete_asset` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-asset.md - `delete_asset_folder` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-asset-folder.md - `delete_branch` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-branch.md - `delete_component` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-component.md - `delete_component_folder` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-component-folder.md - `delete_datasource` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-datasource.md - `delete_datasource_entry` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-datasource-entry.md - `delete_preset` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-preset.md - `delete_release` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-release.md - `delete_space` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-space.md - `delete_space_role` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-space-role.md - `delete_story` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-story.md - `delete_story_scheduling` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-story-scheduling.md - `delete_tag` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-tag.md - `delete_webhook` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-webhook.md - `delete_workflow` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-workflow.md - `delete_workflow_stage` — Destructive — https://policylayer.com/tools/arjuncodess-storyblok-mcp/delete-workflow-stage.md - `create_branch_deployment` — Execute — https://policylayer.com/tools/arjuncodess-storyblok-mcp/create-branch-deployment.md - `deploy_branch` — Execute — https://policylayer.com/tools/arjuncodess-storyblok-mcp/deploy-branch.md - `backup_space` — Other — https://policylayer.com/tools/arjuncodess-storyblok-mcp/backup-space.md - `ping` — Other — https://policylayer.com/tools/arjuncodess-storyblok-mcp/ping.md - `compare_branches` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/compare-branches.md - `fetch_access_tokens` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-access-tokens.md - `fetch_asset_folders` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-asset-folders.md - `fetch_assets` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-assets.md - `fetch_branch_deployments` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-branch-deployments.md - `fetch_component_folders` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-component-folders.md - `fetch_components` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-components.md - `fetch_datasource_entries` — Read — https://policylayer.com/tools/arjuncodess-storyblok-mcp/fetch-datasource-entries.md - …and 84 more: https://policylayer.com/tools/arjuncodess-storyblok-mcp.md ## For agents This record is a snapshot.
