Zulip

Enables AI agents to send messages to Zulip streams and topics, and retrieve message history with full context. Implements MCP tool bindings that translate agent requests into Zulip REST API calls, handling authentication via API tokens and managing message formatting for rich text rendering. Supports querying messages by stream, topic, sender, and date range with pagination for large result sets.

Allows AI agents to create, list, and manage Zulip streams and topics programmatically through MCP tool bindings. Implements CRUD operations that map to Zulip's stream management API, handling permissions validation, stream visibility settings (public/private), and topic creation within existing streams. Supports querying stream metadata including subscriber counts, creation dates, and description fields.

Allows AI agents to pin important messages to streams or topics, and manage bookmarks for individual users through MCP tools that map to Zulip's pinning and bookmarking APIs. Implements pin/bookmark enumeration with metadata (pinner, timestamp, reason), supporting agents in highlighting important information or decisions. Handles pin removal and bookmark management for conversation curation.

Enables AI agents to compose draft messages, schedule messages for future delivery, and manage message templates through MCP tools that integrate with Zulip's drafts and scheduling APIs. Implements draft persistence, template variable substitution, and scheduled message queuing with delivery time management. Supports agents in preparing messages without immediate posting, enabling review or conditional delivery.

Provides MCP tools to edit and delete messages, with support for tracking edit history. Implements message modification by wrapping Zulip's /messages/{message_id} endpoint, allowing agents to update message content and delete messages. Supports retrieving edit history to maintain an audit trail of changes.

Provides MCP tools to schedule messages for future delivery and manage message queues. Implements scheduling by storing message metadata and delivery times, allowing agents to compose messages that are sent at specified times. Supports queue management with priority levels and batch sending capabilities.

Exposes MCP tools to pin and unpin messages, marking them as important or featured. Implements pinning by wrapping Zulip's message pinning API, allowing agents to highlight important messages in streams or topics. Supports querying pinned messages to retrieve important content.

Provides MCP tools to rename topics and reorganize messages across streams. Implements topic management by wrapping Zulip's topic editing API, allowing agents to rename topics for clarity and move messages between topics or streams. Supports bulk topic operations for workspace reorganization.

Provides AI agents with tools to query user profiles, list organization members, and manage user metadata through MCP bindings to Zulip's user management API. Implements member enumeration with filtering by role (admin, moderator, member), status (active/inactive), and custom profile fields. Supports retrieving user presence information and recent activity timestamps for context-aware agent decisions.

Enables AI agents to subscribe to Zulip events (messages, reactions, presence changes, stream updates) through MCP tool bindings that establish long-polling or webhook connections to the Zulip server. Implements event filtering by type and stream, with automatic reconnection and backoff logic for handling connection failures. Agents receive structured event payloads containing full context (sender, timestamp, content) for reactive decision-making.

Allows AI agents to add, remove, and query emoji reactions on Zulip messages through MCP tools that map to Zulip's reaction API. Implements reaction management with support for custom emoji, reaction enumeration by message, and reaction counting for sentiment analysis or engagement tracking. Handles emoji name normalization and validation against the Zulip server's emoji set.

Enables AI agents to search Zulip messages using full-text search with filters for sender, stream, topic, and date range through MCP tool bindings to Zulip's search API. Implements query parsing and filter composition, returning ranked results with message context (surrounding messages for conversation flow). Supports advanced search operators (e.g., 'from:user', 'stream:general', 'has:link') for precise queries.

Provides AI agents with tools to query Zulip analytics including message counts, user activity, stream popularity, and engagement metrics through MCP bindings to Zulip's analytics API. Implements aggregation by time period (daily, weekly, monthly), stream, and user, with support for custom date ranges. Returns structured metrics suitable for trend analysis, reporting, or anomaly detection.

Allows AI agents to read and write custom profile fields and message metadata through MCP tools that map to Zulip's custom field API. Implements field type validation (text, dropdown, date) and supports querying users by custom field values. Enables agents to enrich messages with structured metadata for categorization, routing, or workflow automation.

Provides AI agents with tools to send direct messages, @mentions, and alerts to specific users or groups through MCP bindings to Zulip's messaging API. Implements recipient resolution (username to user ID), group mention expansion, and alert formatting with priority levels. Supports conditional routing based on user presence, role, or custom fields for intelligent notification delivery.

Enables AI agents to navigate and manage Zulip's conversation threading model (streams and topics) through MCP tools that query topic hierarchies, move messages between topics, and manage topic metadata. Implements topic enumeration with message counts and last activity timestamps, supporting agents in understanding conversation structure and organizing discussions. Handles topic renaming and archival for conversation lifecycle management.
