Blog Automation

Blog Automation MCP server

Model Context Protocol server for Blog Automation (https://blog-automation.com): plan ideas, write articles with AI, publish or schedule them on WordPress and check the token balance – from Claude, ChatGPT, Cursor or any MCP client. It is a thin wrapper around the Customer API https://app.blog-automation.com/api/v1/ext (app repo blogposter-app, server/routes/ext.js, docs/API.md). Node 22, @modelcontextprotocol/sdk 1.32, zod 4. Package @blogautomation/mcp-server, command blog-automation-mcp.

Tools

Tool	API call	Notes
list_ideas	GET /ideas	status, siteId, limit, cursor – read only
create_idea	POST /ideas	title (+ keyword, notes, audience, priority 1–3, language, siteId); Idempotency-Key
write_article	POST /articles/generate { …, async: true } → 202 { job }, then GET /jobs/{id} every 3 s	uses tokens; waits ≈ 50 s, then returns jobId (→ job_status); answer without HTML; Idempotency-Key
job_status	GET /jobs/{id}	running / done (article) / failed (error)
list_articles	GET /articles	status list, siteId, q, limit, cursor (no HTML)
get_article	GET /articles/{id}	with HTML and SEO fields
article_status	GET /articles/{id}/status	status, schedule, WordPress link, last error, job
publish_article	POST /articles/{id}/publish or, with at, POST /articles/{id}/schedule	at = ISO time or "next" (next free slot = "add to calendar")
token_balance	GET /tokens	balance, lots, prices
list_sites	GET /sites	WordPress sites (ids for siteId)
list_templates	GET /templates	built-in b:… and own templates

Errors come back as readable tool results with isError: true: 401 (key invalid/revoked), 402 (not enough tokens: needed / balance), 403 insufficient_scope (which scope is missing) / plan_required (which plans have the API), 404, 429 (seconds from Retry-After).

API key

Blog Automation → Entwickler / API → "API-Key erstellen" (plans Starter and Pro). Scopes: articles:read, articles:write, ai:generate (write_article), articles:publish (publish_article), ideas:read, ideas:write, templates:read, sites:read, account:read (token_balance). Leave out what the assistant should not do – e.g. without articles:publish it can write drafts but never publish.

Use it

stdio (local; the key comes from BA_API_KEY):

npx -y @blogautomation/mcp-server          # once published; from this repo: node mcp/src/cli.js

Claude Desktop (claude_desktop_config.json) / Cursor (~/.cursor/mcp.json) – same block:

{ "mcpServers": { "blog-automation": { "command": "npx", "args": ["-y", "@blogautomation/mcp-server"], "env": { "BA_API_KEY": "ba_live_…" } } } }

Claude Code: claude mcp add blog-automation --env BA_API_KEY=ba_live_… -- npx -y @blogautomation/mcp-server

Streamable HTTP (remote clients – ChatGPT connectors / developer mode, Claude "custom connector", Cursor via URL):

blog-automation-mcp --http --port 8787 --host 127.0.0.1 --origin https://chatgpt.com,https://claude.ai

• Endpoint POST /mcp (stateless, JSON responses), health check GET /healthz. GET/DELETE on /mcp → 405 (no sessions).
• Every request must send Authorization: Bearer ba_live_…; the key is used only for that request's API calls – not stored, not logged. Missing or malformed → 401 with WWW-Authenticate: Bearer.
• Requests with an Origin header are only accepted from --origin / BA_MCP_ORIGINS (DNS-rebinding protection); without the option browser requests are refused, server-to-server calls (no Origin) work.
• Binds 127.0.0.1 by default; put it behind the reverse proxy (TLS) for public use, e.g. https://mcp.blog-automation.com/mcp.
• OAuth (since 1.1.0): clients that only do OAuth – ChatGPT apps / developer mode, Claude custom connectors, MCP Inspector – just get the URL https://mcp.blog-automation.com/mcp. The 401 points to /.well-known/oauth-protected-resource (RFC 9728), which names https://app.blog-automation.com as authorization server (dynamic client registration, PKCE S256). The person signs in to Blog Automation, sees the requested permissions and clicks "Erlauben"; the access token is a 1-hour API key, refreshed automatically, revocable under Entwickler / API. Env: BA_MCP_RESOURCE (public /mcp URL), BA_OAUTH_ISSUER (app base URL).

ChatGPT app

ChatGPT → Settings → Apps & Connectors → Advanced → Developer mode → "Create" → name "Blog Automation", MCP server URL https://mcp.blog-automation.com/mcp, authentication OAuth → sign in → allow. All tools carry readOnlyHint / destructiveHint annotations, so ChatGPT asks before writing (tokens) or publishing. Listing in the ChatGPT app directory: SUBMISSION.md.

BA_API_BASE overrides the API (e.g. https://pre.blog-automation.com/api/v1/ext).

Develop

cd mcp && npm install && npm test     # node:test – 7 tests, fake API (no network, no key)

Tests: tools/list (names, annotations, schemas), request shape of every tool, Idempotency-Key, async job polling (done / still running / failed), publish vs. schedule, error mapping (401/402/403/404/429), HTTP transport (healthz, 401, Origin 403, 405, tools/list + call with the request's key).
