HTML page: https://policylayer.com/tools/io-stablebaseline-sb/updatememberrole ## Facts - Tool: `updateMemberRole` - Server: Stable Baseline (`https://api.stablebaseline.io/functions/v1/cloud-serve/mcp`) — https://policylayer.com/tools/io-stablebaseline-sb.md - Homepage: https://github.com/stablebaseline/mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: https://app.stablebaseline.io - Server rate-limited: no - Parameters: 3 (3 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `user_id` | string | yes | Target user UUID. | | `organisation_id` | string | yes | Organisation UUID. Must match the credential's organisation. | | `organization_role` | string | yes | | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "updateMemberRole", "arguments": { "user_id": "", "organisation_id": "", "organization_role": "" } } } ``` ## Why updateMemberRole is rated Medium This tool modifies organizational membership data (role assignments) without deleting records, making it Write rather than Destructive. However, the blast radius is high because role changes directly affect access control and organizational authority—a misused promotion could grant an AI agent or attacker admin privileges across the company brain platform. From the tool's own definition: "Tool updates a member's role (admin or member), modifying organizational permissions. Description explicitly states it changes roles and refuses self-promotion, indicating reversible state mutation of access control." Risk signals: Admin/system-level operation ## Use case AI agents use updateMemberRole to create or update resources in Stable Baseline, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stable Baseline environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
