# provision_oauth2_user Provision an OAuth2 user (Ludus 2.0 only). Agent View of the PolicyLayer registry record for `provision_oauth2_user`. HTML page: https://policylayer.com/tools/tjnull-ludus-fastmcp/provision-oauth2-user ## Facts - Tool: `provision_oauth2_user` - Server: Ludus FastMCP (`tjnull/ludus-fastmcp`) — https://policylayer.com/tools/tjnull-ludus-fastmcp.md - Homepage: https://github.com/tjnull/Ludus-FastMCP - 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": "provision_oauth2_user", "arguments": {} } } ``` ## Why provision_oauth2_user is rated Medium Provisioning a user creates a new account/identity in the system, which is a reversible write operation (users can be deleted). It does not execute code, destroy data, or involve finances. Severity is medium because creating unauthorized accounts could grant access to the cyber range environment. From the tool's own definition: "Provision an OAuth2 user" ## Use case AI agents use provision_oauth2_user to create or update resources in Ludus FastMCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ludus FastMCP environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Ludus FastMCP: ```json { "version": "1", "default": "deny", "tools": { "provision_oauth2_user": { "limits": [ { "counter": "provision_oauth2_user_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Ludus FastMCP (230) - `abort_and_remove_range` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/abort-and-remove-range.md - `abort_range_deployment` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/abort-range-deployment.md - `batch_remove_snapshots` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/batch-remove-snapshots.md - `cleanup_old_ranges` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/cleanup-old-ranges.md - `clear_range_access` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/clear-range-access.md - `delete_blueprint` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-blueprint.md - `delete_group` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-group.md - `delete_range` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-range.md - `delete_range_by_user` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-range-by-user.md - `delete_range_object` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-range-object.md - `delete_ranges_by_status` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-ranges-by-status.md - `delete_source` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-source.md - `delete_template` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-template.md - `destroy_vm` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/destroy-vm.md - `remove_ranges_from_group` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-ranges-from-group.md - `remove_snapshot` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-snapshot.md - `remove_user` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-user.md - `remove_users_from_group` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-users-from-group.md - `revoke_range_access` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/revoke-range-access.md - `revoke_range_from_user` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/revoke-range-from-user.md - `rollback_snapshot` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/rollback-snapshot.md - `abort_template_build` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/abort-template-build.md - `apply_adversary_profile` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/apply-adversary-profile.md - `apply_blueprint_to_range` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/apply-blueprint-to-range.md - `apply_defender_profile` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/apply-defender-profile.md - `batch_power_on_hosts` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/batch-power-on-hosts.md - `batch_snapshot_hosts` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/batch-snapshot-hosts.md - `build_container_based_template` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-container-based-template.md - `build_range_from_description` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-range-from-description.md - `build_range_from_scratch` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-range-from-scratch.md - …and 200 more: https://policylayer.com/tools/tjnull-ludus-fastmcp.md ## For agents This record is a snapshot.
