# neuron_update_knowledge_base Update the properties of an existing knowledge base such as name, description, or root instruction. Agent View of the PolicyLayer registry record for `neuron_update_knowledge_base`. HTML page: https://policylayer.com/tools/io-github-conquext-neuron/neuron-update-knowledge-base ## Facts - Tool: `neuron_update_knowledge_base` - Server: Neuron (`neuron-mcp-server`) — https://policylayer.com/tools/io-github-conquext-neuron.md - Install: `npx -y neuron-mcp-server` - Homepage: https://github.com/conquext/neuron - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 4 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `id` | string | yes | Unique identifier of the knowledge base to update | | `name` | string | no | New name for the knowledge base | | `description` | string | no | New description for the knowledge base | | `rootInstruction` | string | no | New root instruction or context | 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": "neuron_update_knowledge_base", "arguments": { "id": "" } } } ``` ## Why neuron_update_knowledge_base is rated Medium This tool creates or modifies data reversibly by updating knowledge base properties. It does not delete data (which would be Destructive), execute arbitrary code (Execute), or move money (Financial). The modification of a 'root instruction' could have downstream effects on bot behavior, but the tool itself performs a reversible Write operation. From the tool's own definition: "Update the properties of an existing knowledge base such as name, description, or root instruction—this modifies existing data (properties of a knowledge base) in a reversible manner." Risk signals: Admin/system-level operation ## Use case AI agents use neuron_update_knowledge_base to create or update resources in Neuron, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Neuron environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Neuron: ```json { "version": "1", "default": "deny", "tools": { "neuron_update_knowledge_base": { "limits": [ { "counter": "neuron_update_knowledge_base_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Neuron (230) - `neuron_delete_ad_request` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-ad-request.md - `neuron_delete_blog_post` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-blog-post.md - `neuron_delete_bot` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-bot.md - `neuron_delete_broadcast` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-broadcast.md - `neuron_delete_campaign` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-campaign.md - `neuron_delete_channel` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-channel.md - `neuron_delete_contact` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-contact.md - `neuron_delete_contact_list` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-contact-list.md - `neuron_delete_kb_entry` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-kb-entry.md - `neuron_delete_knowledge_base` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-knowledge-base.md - `neuron_delete_message` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-message.md - `neuron_delete_newsletter` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-newsletter.md - `neuron_delete_outbound_webhook` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-outbound-webhook.md - `neuron_delete_tool` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-tool.md - `neuron_delete_webhook` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-delete-webhook.md - `neuron_leave_group` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-leave-group.md - `neuron_logout` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-logout.md - `neuron_post_to_newsletter` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-post-to-newsletter.md - `neuron_remove_bot_channel` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-remove-bot-channel.md - `neuron_remove_member` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-remove-member.md - `neuron_remove_profile_picture` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-remove-profile-picture.md - `neuron_remove_tool_secret` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-remove-tool-secret.md - `neuron_revoke_api_key` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-revoke-api-key.md - `neuron_revoke_group_invite` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-revoke-group-invite.md - `neuron_revoke_invitation` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-revoke-invitation.md - `neuron_send_broadcast` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-send-broadcast.md - `neuron_stop_ad_request` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-stop-ad-request.md - `neuron_stop_campaign` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-stop-campaign.md - `neuron_unpublish_from_pool` — Destructive — https://policylayer.com/tools/io-github-conquext-neuron/neuron-unpublish-from-pool.md - `neuron_bot_api_chat` — Execute — https://policylayer.com/tools/io-github-conquext-neuron/neuron-bot-api-chat.md - …and 200 more: https://policylayer.com/tools/io-github-conquext-neuron.md ## For agents This record is a snapshot.
