Use tinyposter from Claude

What you're building

tinyposter has a built-in MCP server. MCP stands for Model Context Protocol — fancy name for “a way AI assistants talk to tools.” Once you connect it, Claude can post, schedule, and check your calendar by itself.

You need:

• A tinyposter account with at least one social account connected
• One of: Claude Desktop (Mac/Windows), Claude.ai (web), Claude Code (terminal), or Claude Cowork
• About 5 minutes

Step 1 — Get a token

A token is like a password Claude will use to talk to tinyposter. It starts with tp_.

1. Open your tokens page.
2. Click Create token. Name it “Claude.”
3. Copy the token. It only shows once.

Step 2 — Pick where you use Claude

A. Claude Desktop (Mac or Windows)

This is the most popular path. Anyone with Claude Desktop installed can use it.

1. 01

   Open the config file

   Click Claude menu (top-left on Mac, hamburger on Windows) → Settings → Developer → Edit Config. This opens claude_desktop_config.json.

   If the menu doesn't open it, you can find it manually:

   • Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
2. 02

   Paste this in

   Replace the whole file with this (or merge with your existing mcpServers):

   claude_desktop_config.jsonjson

   Copy

   {
     "mcpServers": {
       "tinyposter": {
         "url": "https://tinyposter.app/api/mcp",
         "headers": {
           "Authorization": "Bearer tp_PASTE_YOUR_TOKEN_HERE"
         }
       }
     }
   }

   Replace tp_PASTE_YOUR_TOKEN_HERE with the token you copied (keep the word Bearer and the space).

3. 03

   Restart Claude Desktop

   Fully quit Claude — Cmd+Q on Mac, right-click the tray icon → Quit on Windows. Just closing the window isn't enough.

   Re-open Claude. You'll see a small tools icon in the chat input. Click it — tinyposter should be in the list.

B. Claude.ai (web)

Claude.ai supports custom connectors on Pro, Max, and Team plans.

1. 01

   Open the connectors page

   Click your avatar (bottom-left) → Settings → Connectors. Or jump straight to claude.ai/settings/connectors.

   Click Add custom connector.

2. 02

   Fill in the form

   • Name: tinyposter
   • Server URL: https://tinyposter.app/api/mcp
   • Authentication: Bearer Token
   • Token: paste your tp_… token (no Bearer prefix — Claude adds it for you)

   Click Save.

3. 03

   Turn it on in a chat

   Open a new chat. Click the tools icon in the message box and toggle tinyposter on. It stays on for that chat.

C. Claude Code (terminal)

If you use the Claude Code CLI, one command:

claude mcp add --transport http tinyposter https://tinyposter.app/api/mcp \
  --header "Authorization: Bearer tp_PASTE_YOUR_TOKEN_HERE"

Restart Claude Code. Inside any session, run /mcp to confirm tinyposter shows up in the list.

D. Claude Cowork

Cowork is Anthropic's collaborative workspace product. If your team uses it, you can add tinyposter as a workspace-level connector so anyone on the workspace can post.

1. 01

   Open workspace connectors

   In Cowork, open the workspace settings → Connectors (sometimes labeled MCP servers) → Add MCP server (or Add custom connector).

2. 02

   Fill in the form

   • Name: tinyposter
   • URL: https://tinyposter.app/api/mcp
   • Authentication: Bearer Token
   • Token: paste your tp_… token

   Save. The connector is live for everyone on the workspace.

Step 3 — Try it

In any of the three Claude options above, ask:

What social accounts am I connected to on tinyposter?

If it lists your platforms, it works. Now try a real post:

Post "hello from Claude" to my Twitter and LinkedIn using tinyposter.

Claude will ask permission the first time it uses a tool. Allow it. The post goes live in about a minute.

Things you can ask Claude

• “Post ‘Friday recap incoming’ to X and LinkedIn.”
• “Schedule a Threads post for Sunday at 9am ET that says...”
• “What's on my schedule next week?”
• “Cancel the post I scheduled for Saturday.”
• “Which platforms am I connected to?”
• “How many posts do I have left this month?”
• “Write a thread about X and post the first tweet to my X account.”

Troubleshooting

Under the hood

The MCP server is at https://tinyposter.app/api/mcp. It speaks JSON-RPC 2.0 over HTTP. Full tool reference is on the MCP page.

Next

• MCP reference — every tool, every input
• HTTP API — same actions over plain REST
• Codex / coding agents — different agent, same idea
