This guide walks you through the easiest and most secure way to connect your Buffer account to Cowork via Composio Connect, enabling it to schedule LinkedIn posts for next week, list queued Buffer posts by channel, draft tweets for product launch, and more such actions on your behalf without compromising your account security.

## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like Buffer through MCP without you sharing account credentials directly with the agent.

## What is the Buffer MCP server, and what's possible with it?

The Buffer MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Buffer account. It provides structured and secure access so your agent can perform Buffer operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `BUFFER_CREATE_IDEA` | Create Idea | Create a persistent content idea in a Buffer organization. Buffer's public API provides no operation to update or delete an idea after creation, so this action cannot be undone through the API. |
| `BUFFER_CREATE_POST_DRAFT` | Create Post Draft | Create an internal text-post draft for exactly one Buffer channel. This action always saves a draft and does not queue, schedule, or publish it. |
| `BUFFER_DELETE_POST` | Delete Post | Permanently delete a Buffer post by ID, including a draft created for cleanup. This operation cannot be undone. |
| `BUFFER_DELETE_POST_TEMPLATE` | Delete Post Template | Delete a writable private Buffer template, or an internal template when the connected user is an organization admin or owner. This operation cannot be undone. |
| `BUFFER_GET_ACCOUNT_CONTEXT` | Get Account Context | Return the connected Buffer account, its organizations, and the accessible social channels in each organization so an agent can discover the IDs required by other tools. |
| `BUFFER_LIST_IDEA_GROUPS` | List Idea Groups | List the idea workflow groups in a Buffer organization so an agent can discover group IDs for filtering or idea creation. |
| `BUFFER_LIST_IDEAS` | List Ideas | List content ideas in a Buffer organization, optionally filtering by explicit idea groups or grouped versus ungrouped workflow membership. |
| `BUFFER_LIST_POSTS` | List Posts | List and filter posts in a Buffer organization without requesting OAuth-inaccessible analytics fields. |
| `BUFFER_LIST_POST_TEMPLATES` | List Post Templates | List Buffer public templates and templates visible to the connected user in an organization, optionally filtered by visibility. |
| `BUFFER_PUBLISH_POSTS` | Publish Posts | Queue, schedule, or immediately publish the same text post to one to 10 Buffer channels. The 10-channel cap bounds external side effects and provider requests in one invocation. Calls are non-atomic: one createPost mutation runs per channel, and successful channels may already be queued, scheduled, or published when another channel fails. Returns every success and provider failure instead of rolling successful channels back. |
| `BUFFER_SAVE_POST_TEMPLATE` | Save Post Template | Create a private or internal Buffer post template, or update an existing writable template when template_id is supplied. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Buffer MCP?

With a standalone Buffer MCP server, the agents and LLMs can only access a fixed set of Buffer tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Buffer and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Buffer tools.

### Can I manage the permissions and scopes for Buffer while using Tool Router?

Yes, absolutely. You can configure which Buffer scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Buffer data and credentials are handled as safely as possible.
