# threads_update ✏️ Update a conversation thread: rename it, add notes/description, or move to a folder. When to use: - User wants to rename a chat or group - User wants to add notes/context about a conversation - User wants to organize threads into folders For DM threads, renaming also updates the linked contact's display name by default. Requires thread_id from threads.list. Agent View of the PolicyLayer registry record for `threads_update`. HTML page: https://policylayer.com/tools/io-github-saloprj-dialogbrain/threads-update ## Facts - Tool: `threads_update` - Server: Dialogbrain (`https://api.dialogbrain.com/mcp`) — https://policylayer.com/tools/io-github-saloprj-dialogbrain.md - Homepage: https://github.com/saloprj/dialogbrain-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server rate-limited: no - Parameters: 5 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `title` | string | no | New title for the thread (max 255 chars) | | `folder_id` | integer | no | Move thread to this folder (null removes from folder) | | `thread_id` | string | yes | Thread ID from threads.list | | `description` | string | no | AI context / notes for this thread. Empty string clears description. | | `update_contact` | boolean | no | For DM threads, also rename the linked contact (default: true) | 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": "threads_update", "arguments": { "thread_id": "" } } } ``` ## Why threads_update is rated Medium This tool modifies existing data reversibly without deleting or executing arbitrary code. Updates to thread names, descriptions, and folder organization are typical Write operations. Severity is medium because unintended modifications could disrupt conversation organization and context (e.g., renaming a DM also updates the contact's display name by default), affecting multiple users, but changes are reversible. From the tool's own definition: "Tool updates conversation metadata (rename, add notes/description, move to folder). Description explicitly states '✏️ Update' and lists modification operations: rename, add notes/description, organize into folders." ## Use case AI agents use threads_update to create or update resources in Dialogbrain, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Dialogbrain environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
