@writavo/mcp-server

Your Writavo Site's content, inside an AI assistant. Draft a post, set its category and byline, attach an image, schedule it, publish it, all from a conversation.

It speaks the Model Context Protocol over stdio, so it runs as a subprocess of your client rather than as a service you host.

Install

{
  "mcpServers": {
    "writavo": {
      "command": "npx",
      "args": ["-y", "@writavo/mcp-server"],
      "env": { "WRITAVO_API_KEY": "wv_sk_your_key_here" }
    }
  }
}

Create the key at https://app.writavo.com/settings/api-keys and give it only the scopes you want the assistant to have. A key never outranks the person who made it: narrowing your own permissions narrows every key you created, on the next request.

Without a key the server still starts and get_api_docs still works, so you can read the whole API reference before signing up.

What it can do

Thirty six tools are compiled from Writavo's published OpenAPI specification, plus two written by hand:

• Articles. List, read, create, update, delete, publish, unpublish, schedule, cancel a schedule.

• Taxonomy and people. Categories, tags and authors: list, read, create, update, delete.

• Media. List, read, update, delete, and upload_media, which drives the whole three step presigned upload in one call so the assistant does not have to orchestrate it.

• Pipeline. Trigger a run, read its status, read the queue.

• Meta. Site information, content types, plan usage and balances, and get_api_docs, which needs no key at all.

What it will not do without asking

publish_article, schedule_article, every delete_* and trigger_pipeline_run do nothing on the first call. They describe what would happen and wait for confirm: true, which the assistant can only set after you have agreed. Publishing puts content on your live site, deleting is permanent, and a pipeline run spends real credits.

Two things are not reachable from an assistant at all, whatever scopes the key carries:

• API keys. A server that can mint a secret key is a server whose compromise mints secret keys, and the key it would use to do so is in a config file on the same machine.

• Webhooks. An assistant that can repoint delivery URLs can quietly redirect your event stream.

Both stay in the dashboard.

What it never writes down

• Your key is sent to https://api.writavo.com/v1 as a bearer header and to nothing else. No telemetry, no analytics, no third-party host. The base URL is read from the specification and cannot be repointed off api.writavo.com by an environment variable.

• Every reply, log line and error is passed through a redactor, so a key cannot reach your transcript even if the API echoed it back inside an error message.

• Standard output carries protocol messages and nothing else. Every console channel is rebound to standard error before the server starts, because one stray line on stdout is a dropped connection.

Errors you might see

Each one is answered with what to change rather than a status code.

The full catalog is in get_api_docs under errors, and at https://writavo.com/docs/errors.

Prompts

• draft-article. Research a topic and write a draft in your Site's own voice. It never publishes or schedules.

• publish-checklist. Walk an existing draft through title, slug, SEO fields, excerpt, category, author and featured image, then ask before publishing.

Development

This package lives in the Writavo monorepo. Its tool schemas, descriptions and reference text are generated, not written:

npm run gen         regenerate from the vendored openapi.yaml
npm test            run the 44 offline smoke checks
npm run gen:check   fails if the committed tool surface is stale

Adding an endpoint to openapi.yaml and regenerating is the whole of adding a tool. Editing anything under src/generated/ fails CI.
