Bracket Coder — Blog MCP (AI blog writer)

An MCP server that lets Claude (Claude Code or Claude Desktop) research, write, illustrate and publish SEO blog posts straight to bracketcoder.com/admin/blogs.

Claude gets tools to read the style guide, list categories/tags/posts (for context + internal linking), generate on-brand images (Gemini → Bunny CDN), and create/update posts with full SEO fields — following style_guide.md (long-form, table/graph when the topic needs it, 2–3 images, internal + external links, meta/slug/tags, E-E-A-T).

Auth is a browser login (loopback, like gh auth login): you sign in as admin once, a scoped, revocable token is issued and cached locally — nothing to copy by hand.

Setup

1. Clone & install

git clone https://github.com/bracketcoder/blog-mcp.git
cd blog-mcp
python3 -m venv .venv
source .venv/bin/activate           # Windows: .venv\Scripts\activate
pip install -r requirements.txt

2. Log in (browser)

python login.py

Your browser opens the Bracket Coder authorize page → sign in as admin → click Authorize. The token is captured on 127.0.0.1 and cached at ~/.config/bracketcoder-blog/token. You will not see or paste a token.

3. Connect Claude

Claude Code:

claude mcp add bracketcoder-blog -- "$(pwd)/.venv/bin/python" "$(pwd)/server.py"

Claude Desktop — add to claude_desktop_config.json:

{
  "mcpServers": {
    "bracketcoder-blog": {
      "command": "/ABSOLUTE/PATH/blog-mcp/.venv/bin/python",
      "args": ["/ABSOLUTE/PATH/blog-mcp/server.py"]
    }
  }
}

Restart Claude — the bracketcoder-blog tools appear.

Use it (example prompts)

• New post: "Write a Bracket Coder blog post on 'how to reduce SaaS churn in 2026'. Follow the style guide, add a table and a graph, 3 images, internal + external links, save as a draft."
• Rewrite: "Rewrite the post at /insights/how-much-does-it-cost-to-build-a-custom-web-app-in-2026 — longer, add a cost table, a budget graph and 2 images, then update it."
• Publish: add "…and publish it."

Claude will read the style guide → pick a category + tags + internal links → draft SEO HTML with a table/graph → generate 2–3 images → create/update the post → return the live /insights/<slug> URL.

Security

• .env and the cached token are gitignored / local-only — never commit them.
• The login token is scoped to blog content only and revocable by an admin (Django admin → MCP Tokens). Run login.py again to get a fresh one.
