# neuron_list_knowledge_bases Retrieve all knowledge bases accessible to the current user. Agent View of the PolicyLayer registry record for `neuron_list_knowledge_bases`. HTML page: https://policylayer.com/tools/io-github-conquext-neuron/neuron-list-knowledge-bases ## Facts - Tool: `neuron_list_knowledge_bases` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "neuron_list_knowledge_bases", "arguments": {} } } ``` ## Why neuron_list_knowledge_bases is rated Low This tool retrieves and enumerates knowledge bases accessible to the user. It performs a read-only query with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal: an attacker gains visibility into what knowledge bases exist but cannot access their contents or modify them without additional tools. Low severity is appropriate for information disclosure of object inventories. From the tool's own definition: "Tool name contains 'list' and description states 'Retrieve all knowledge bases' — a query operation with no side effects." ## Use case AI agents call neuron_list_knowledge_bases to retrieve information from Neuron without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Neuron: ```json { "version": "1", "default": "deny", "tools": { "neuron_list_knowledge_bases": {} } } ``` ## 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.
