Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
chatra_get_visitorA chat visitor by id: name and contact details (basicInfo, integrationData and the merged `info`), custom form answers, location, browser, the link to the chat in the Chatra dashboard, the agent group, and the pages viewed in the latest visit. The id is the `clientId` your websit
chatra_update_visitorWRITE: edit a visitor's basic info (name, email, phone, notes) exactly as if an agent edited it in the Chatra dashboard. Only the fields you pass change; `null` removes a value. Returns the updated visitor. PUT /clients/{id}.
chatra_get_messageOne chat message by id (a visitor's or an agent's): type (agent or client), text, visitor id, agent id, timestamp (ms) and receivedFrom. Chatra has no endpoint to list a conversation, so the id must come from a send call or a webhook. GET /messages/{id}.
chatra_send_messageWRITE: send a chat message to a visitor as a Chatra agent. The visitor sees it immediately in their chat window as if the agent typed it, so only call it with text the user asked you to send. It cannot be unsent except by deleting it. Say which agent writes: agent_id, or agent_em
chatra_edit_messageWRITE: replace the text of an agent message that was sent earlier. Only agents' messages can be edited, not visitors'. The visitor sees the edited text. Returns the updated message. PUT /messages/{id}.
chatra_delete_messageWRITE, IRREVERSIBLE: delete an agent message from the conversation. Only agents' messages can be deleted, not visitors'. Returns the deleted message. DELETE /messages/{id}.
chatra_get_pushed_messageOne pushed (automated) message sent earlier by id: text, visitor id, agent id, timestamp (ms), isPushed. GET /pushedMessages/{id}.
chatra_push_messageWRITE: send an automated message (order status, product update, announcement) to a visitor whose account is bound to Chatra through a clientId. It is delivered into the visitor's chat on behalf of a random agent, a given agent (agent_id) or a random agent of a group (group_id). I
chatra_edit_pushed_messageWRITE: replace the text of a pushed message sent earlier; the visitor sees the edited text. Returns the updated message. PUT /pushedMessages/{id}.
chatra_delete_pushed_messageWRITE, IRREVERSIBLE: delete a pushed message sent earlier. Returns the deleted message. DELETE /pushedMessages/{id}.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
