# transkribus_coll_user_add_or_modify Add a user to a collection or modify their role if they already exist. Agent View of the PolicyLayer registry record for `transkribus_coll_user_add_or_modify`. HTML page: https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-coll-user-add-or-modify ## Facts - Tool: `transkribus_coll_user_add_or_modify` - Server: Transkribus (`@lazyants/transkribus-mcp-server`) — https://policylayer.com/tools/io-github-lazyants-transkribus.md - Install: `npx -y @lazyants/transkribus-mcp-server` - Homepage: https://github.com/lazyants/transkribus-mcp-server - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "transkribus_coll_user_add_or_modify", "arguments": {} } } ``` ## Why transkribus_coll_user_add_or_modify is rated Medium This tool modifies collection membership and user roles, which are data-state changes that can be reversed (users can be removed or roles changed back). It does not delete data, execute code, move money, or trigger irreversible actions. The blast radius is medium because an AI misusing this could grant unauthorized access to collections, but access can be revoked. From the tool's own definition: "Tool name includes 'add_or_modify' and description states 'Add a user to a collection or modify their role' — both are reversible write operations that create or update user access." ## Use case AI agents use transkribus_coll_user_add_or_modify to create or update resources in Transkribus, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Transkribus environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Transkribus: ```json { "version": "1", "default": "deny", "tools": { "transkribus_coll_user_add_or_modify": { "limits": [ { "counter": "transkribus_coll_user_add_or_modify_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Transkribus (300) - `transkribus_coll_credit_remove_package` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-coll-credit-remove-package.md - `transkribus_coll_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-coll-delete.md - `transkribus_coll_delete_empty` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-coll-delete-empty.md - `transkribus_coll_remove_user` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-coll-remove-user.md - `transkribus_coll_user_remove` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-coll-user-remove.md - `transkribus_crowd_delete_messages` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-crowd-delete-messages.md - `transkribus_crowd_delete_milestones` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-crowd-delete-milestones.md - `transkribus_doc_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-doc-delete.md - `transkribus_editdecl_delete_feature` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-editdecl-delete-feature.md - `transkribus_editdecl_delete_option` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-editdecl-delete-option.md - `transkribus_job_undo` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-job-undo.md - `transkribus_label_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-label-delete.md - `transkribus_label_remove_all_documents` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-label-remove-all-documents.md - `transkribus_label_remove_all_pages` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-label-remove-all-pages.md - `transkribus_label_remove_pages` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-label-remove-pages.md - `transkribus_model_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-model-delete.md - `transkribus_model_delete_by_type` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-model-delete-by-type.md - `transkribus_model_remove_collection` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-model-remove-collection.md - `transkribus_model_remove_collection_by_id` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-model-remove-collection-by-id.md - `transkribus_page_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-page-delete.md - `transkribus_page_delete_transcript` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-page-delete-transcript.md - `transkribus_recog_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-recog-delete.md - `transkribus_recog_remove_from_collection` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-recog-remove-from-collection.md - `transkribus_search_reset_index` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-search-reset-index.md - `transkribus_upload_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-upload-delete.md - `transkribus_user_delete` — Destructive — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-user-delete.md - `transkribus_admin_rebuild_models_index` — Execute — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-admin-rebuild-models-index.md - `transkribus_du_recognize` — Execute — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-du-recognize.md - `transkribus_job_create` — Execute — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-job-create.md - `transkribus_job_restart_all_by_user` — Execute — https://policylayer.com/tools/io-github-lazyants-transkribus/transkribus-job-restart-all-by-user.md - …and 270 more: https://policylayer.com/tools/io-github-lazyants-transkribus.md ## For agents This record is a snapshot.
