Wazap
Communication · Local stdio
Quality: 52/100 (Good) | Auth: No auth required

Which MCP Server Should You Choose?
W
Choose WaAPI when:
You need dedicated capabilities in the Communication domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Messages in a chat; `before` pages further back, pulling older history from the phone; `types` narrows to one or more message types, e.g. `["call"]`; `include_previews` attaches a small image of each photo.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
WaAPI is categorized under Communication and uses a remote streaming HTTP/SSE transport. In contrast, Wazap belongs to Communication using local stdio subprocess. Select WaAPI when you need capabilities focused on communication and Wazap when you require tools for communication.
Everything from the last N hours, grouped by chat. The catch-up tool. `include_system` adds WhatsApp's own notices, `types` narrows to one or more message types, `include_previews` attaches a small image of each photo, `compact` halves it for a routine catch-up.
get_unanswered
Who is waiting on the user: chats whose last word is theirs and asks for something, with the ask quoted. Groups only when the user was @-mentioned or replied to.
set_contact_note
Remember something about a person, on this machine only; it then shows next to their name everywhere.
mark_handled
Take a chat off `get_unanswered` until the other side writes again. Nothing changes on WhatsApp.
get_stories
The stories (status updates) received in the last day, by author, with previews on request. They show nowhere else.
wait_for_messages
Block up to 55 s until a message arrives, then return it with a cursor for the next call. `addressed_to_me` wakes only for direct messages, @-mentions and replies.
search_messages
Text search across the locally held messages; `since`, `until` and `from` narrow it.
