Mastodon + ChatGPT

Read & post on any Mastodon instance from any AI agent. 10 tools, Bearer token auth.

Requisitos previos

Las instrucciones de configuración completas están incluidas en el conector (visibles en el store al seleccionarlo). Las variables de entorno requeridas:

MASTODON_INSTANCE_URL, MASTODON_ACCESS_TOKEN

Paso 1 — Obtener credenciales

This connector wraps the Mastodon REST API (any instance — set baseUrl to your instance).

Setup:

  1. Pick your instance (e.g. https://mastodon.social, https://fosstodon.org, your self-hosted one).
  2. Log in → Preferences → Development → New application.
  3. Name it (e.g. 'mcp'). Scopes: read, write, follow, push — tick whatever your use case needs (don't over-grant).
  4. Save → copy the Your access token value (shown only once). This is a personal access token tied to your account.
  5. Set MASTODON_INSTANCE_URL (e.g. https://mastodon.social) and MASTODON_ACCESS_TOKEN.

Authentication: Authorization: Bearer ${MASTODON_ACCESS_TOKEN} on every request.

…(continued in the in-app connector instructions)

Paso 2 — Instalar el adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Paso 3 — Añadir el conector en ChatGPT

ChatGPT soporta servidores MCP a través de la función Connectors (planes Plus / Pro / Team / Enterprise). El plan gratuito no admite conectores personalizados.

  1. Abre ChatGPT → Settings → Connectors (o pulsa el icono 🔧 en el composer → Manage connectors).
  2. Pulsa "Add custom connector".
  3. Rellena:
    • Name: Mastodon
    • MCP server URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → pega tu MCP API key (de AnythingMCP → Profile → MCP API Keys → New Key)
  4. Pulsa Connect para autorizar.
