It performs simple querying and filtering on existing data. The blast radius of misuse is minimal—an attacker could view newsletters but cannot create, modify, delete, or cause financial harm. This is a standard read-only data access operation. From the tool's own definition: "Tool description states 'Retrieve a paginated list' of newsletters, which is a data retrieval operation with no side effects. The verb 'Retrieve' and the structure 'list...newsletters' are characteristic of Read operations." ## Use case AI agents call neuron_list_newsletters 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_newsletters": {} } } ``` ## 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.
