# AI agents that post and reply on X, with your approval > Let Claude or your own agent post, reply and answer DMs from its own X account: local MCP account tools that ask before every write, and Python, Node.js and Go SDKs. $0.065 to $0.10 per 1,000 calls. HTML page: https://www.twittrapi.com/use-cases/agents-that-post Solutions · AI agents that post Let Claude or your own agent draft posts, reply to people and answer DMs from its own X account, and approve each write before it goes out. Each action is one call, the same price as a read: $0.065 to $0.10 per 1,000.

Setup ## Two ways to give an agent write access Both use the X session (cookie) of the agent's account and a proxy. - Local MCP server The open-source twittrapi-mcp server on your machine, over stdio. Set `TWITTRAPI_X_COOKIE` and `TWITTRAPI_X_PROXY` and it adds account tools next to the read tools. [Setup guide](https://github.com/twittrapi/twittrapi-mcp#account-tools) [Setup guide](https://github.com/twittrapi/twittrapi-mcp#account-tools) - SDKs for your own agent (1.1.0) The Python, Node.js and Go SDKs have an account API: post, reply, upload media, drafts and DMs, with your own approval step in between. [Setup guide](https://github.com/twittrapi/twittrapi-python#account-actions) [Setup guide](https://github.com/twittrapi/twittrapi-python#account-actions) [Get the cookie and set up a proxy](https://www.twittrapi.com/docs/x-session) Human in the loop ## You confirm every write The MCP server marks every tool that writes as not read-only, and deletions also as destructive. MCP clients such as Claude and Cursor then ask you before each call. - Keep the approval prompts on. Read the text before you allow it. - The cookie and proxy stay in the server's configuration; the model never sees them. - Account tools only run over stdio on your machine. The hosted MCP server stays read-only. - Each tool description tells the model to post only text you asked for. Direct messages also need `TWITTRAPI_X_CHAT_PASSCODE`. Use your own account or one you're authorised to manage, and follow [X's rules on automation](https://help.x.com/en/rules-and-policies/x-automation). Tools ## What the agent can do MCP tool names, and the account action each one calls. - Post a tweet, a quote or a poll create_tweet [/client/create](https://www.twittrapi.com/docs/account-actions/client-create) - Reply to a tweet reply_to_tweet [/client/reply](https://www.twittrapi.com/docs/account-actions/client-reply) - Save a draft for you to finish create_draft [/client/drafts/create](https://www.twittrapi.com/docs/account-actions/client-drafts-create) - Read the DM inbox list_dm_conversations [/client/dm/inbox](https://www.twittrapi.com/docs/account-actions/client-dm-inbox) - Send a direct message send_dm [/client/dm/send](https://www.twittrapi.com/docs/account-actions/client-dm-send) - Delete one of its own tweets delete_tweet [/client/deleteTweet](https://www.twittrapi.com/docs/account-actions/client-deletetweet) The full list is in the [twittrapi-mcp README](https://github.com/twittrapi/twittrapi-mcp#account-tools); every endpoint is on [Account actions](https://www.twittrapi.com/docs/account-actions). Your own agent ## The account API in the SDKs From version 1.1.0, each SDK takes the agent's X session once and exposes the account actions as methods. Let the model propose the text, show it to a person, and only then call the method. - Python client.account.reply("", "") [README](https://github.com/twittrapi/twittrapi-python#account-actions) - Node.js client.account({ cookie, proxy }) [README](https://github.com/twittrapi/twittrapi-node#account-actions) - Go client.Account(twittrapi.XSession{…}) [README](https://github.com/twittrapi/twittrapi-go#account-actions) Writes are not retried once the request may have reached the API, so a retry never posts twice. Draft first with `create_draft` when a person should finish the post on x.com. FAQ ## Questions about agents that post **Can the agent post without asking me?** Not through the MCP server's account tools if you keep your client's approval prompts on: every tool that writes is marked as not read-only, so Claude, Cursor and other clients ask before each call. With the SDKs you build the approval step into your own loop. **Why only the local MCP server?** The account tools need the X session cookie and a proxy, and those stay in your own machine's configuration. The hosted MCP server and HTTP mode only offer the read tools. **Does the model see my cookie?** No. The cookie and proxy are server settings, not tool arguments, so they never reach the model and are never logged or returned in a tool result. **Which account should the agent post from?** Its own: a dedicated X account for the agent, labelled as automated in its profile settings, rather than your personal account. That keeps its posts clearly separate and follows X's rules for automated accounts. **Can a retry post the same reply twice?** The SDKs do not retry a write once the request may have reached the API, so a retry never posts twice. Reads still retry as usual.
