Buffer MCP server for Claude, Codex and Cursor

Plan and schedule social media posts with Buffer. Connect the Buffer MCP server to Toolstile once, then choose which of its tools Claude Code, Codex, Cursor and Claude Desktop may use.

Free plan available. Server credentials stay in Toolstile, not in agent configs.

Buffer MCP tools

17 tools, taken from the publisher's documentation on 31 October 2026. The server decides what it offers and can add or rename tools at any time; after you connect, Toolstile shows the current list.

ToolWhat it does
get_accountReturns the signed-in user and their organizations with IDs, plan limits and member counts.
list_channelsLists an organization's connected social channels with ID, name, service, type and connection status.
get_channelReturns details for one channel, such as posting schedule, queue status, timezone and service-specific data.
list_postsLists an organization's posts, filterable by channel, status, tag and date, with optional metrics.
get_postReads one post in full, including metadata, assets, allowed actions, errors and optional analytics.
create_postSchedules or publishes a post on one channel, with service-specific metadata, threads and assets.
edit_postModifies an existing post; omitted fields are kept, sent arrays or metadata objects replace the stored ones.
delete_postPermanently deletes a post when deletion is among its allowed actions.
get_aggregated_post_metricsReturns totals and averages of post analytics over a date range of up to 365 days.
list_ideasLists an organization's ideas, filterable by tag.
list_idea_groupsLists the ideas board columns with ID, name and lock status.
create_ideaSaves a new idea without scheduling or publishing anything.
list_post_templatesLists the public, internal and private post templates, optionally filtered by visibility.
get_post_templateReads one template's body, title, description, emoji, visibility and timestamps.
create_post_templateCreates a private or internal post template that may contain placeholders.
update_post_templateUpdates only the template fields that are sent.
delete_post_templatePermanently deletes a post template.

Suggested access for each AI app

The documentation this list comes from doesn't mark Buffer's tools as read-only or destructive. Read each tool's description and decide per app before allowing it.

Coding agent in Claude Code or Cursor. Allow the read tools so the agent can look things up without stopping, and require approval for tools that change shared data.

Chat or research app in Claude Desktop. Allow reading and searching. Allow writes only where you want the app to act for you.

Unattended agent, such as a scheduled Codex job. No one is watching the session, so keep it narrow: allow what the job needs, require approval for changes and block the rest.

Blocked tools are removed from the tool list an app sees, so it won't try them. Because rules apply per app, the same Buffer connection can be broad in one app and read-only in another, and the credential stays in Toolstile instead of each app's config file.

How it works with Toolstile

  1. Connect once. Add Buffer to a workspace (browser sign-in). Toolstile keeps the credential, so no agent config holds it.
  2. Choose access per app. Give Claude Code every Buffer tool, give Cursor only the read tools, or keep Buffer away from an app entirely.
  3. Share approved accounts. Teammates use the connection without copying tokens, and you can remove access in one place.
  4. Review activity. See which app called which tool and when, so you can tighten access with evidence.

Add the Buffer MCP server to an AI app

Through Toolstile, every AI app uses one gateway entry, whichever servers you connect. In Claude Code:

Shell
claude mcp add --transport http toolstile 'https://mcp.toolstile.com/mcp'

Then connect Buffer in your workspace and choose which of its tools that app may use. Client setup covers Codex, Cursor and Claude Desktop.

To connect directly instead, add the Buffer endpoint to each app separately. In Claude Code:

Shell
claude mcp add --transport http buffer 'https://mcp.buffer.com/mcp'

In Cursor's mcp.json:

JSON
{
  "mcpServers": {
    "buffer": {
      "url": "https://mcp.buffer.com/mcp"
    }
  }
}

Some servers accept only clients they have approved, or need a token header. Check the Buffer MCP documentation for what your client needs.

Before you connect

A Buffer account. Sign-in uses your Buffer permissions.
