mcp-server-juejin

Provides an MCP server (Spring AI MCP Server, stdio mode) that lets an AI tool create article drafts and publish articles to Juejin using a user-provided Juejin login cookie. Accepts Markdown content and tags, and exposes a tool method (saveArticleToJueJin) that calls Juejin content APIs.

Secret Handling

Uses a Juejin cookie for authentication (strength limited; no OAuth/session hardening described). Cookie is provided via config; README does not indicate secure secret storage, redaction in logs, or least-privilege. TLS is not explicitly discussed, though typical deployments use HTTPS; stdio mode implies local transport but outbound calls to api.juejin.cn are expected to be HTTPS.

Best When

You want a lightweight local/hosted MCP stdio server that an agent can call to draft and publish single articles (with human/agent review) to Juejin.

Avoid When

Avoid using it for high-volume publishing without clear rate-limit handling, retries, and idempotency; avoid in contexts where credentials (cookie) cannot be securely managed.

Use Cases

• AI-assisted drafting and publishing of Juejin articles
• Automating creation of article drafts then publishing after review
• Markdown-to-Juejin posting workflows for teams or personal content pipelines

Not For

• Highly regulated publishing workflows requiring strong audit trails and approvals inside the service
• Environments where storing or transmitting Juejin cookies is not allowed
• Bulk automated publishing at high rate without operational safeguards

Authentication

Methods: Juejin login Cookie (cookie-based authentication)

OAuth: No Scopes: No

Authentication is via a configured Juejin cookie in application.yml. No OAuth or fine-grained scopes are described.

Pricing

Free tier: No

Requires CC: No

No pricing information for the software package/service is provided; it appears to be a self-hosted open-source project.

Retry Guidance

Known Gotchas

⚠ Cookie expiration is noted; agents may repeatedly fail until the cookie is refreshed.
⚠ Rate limits are mentioned but no structured retry/backoff/idempotency behavior is documented, so agents may need external safeguards.
⚠ Tool interface is described at a high level; precise MCP tool schema/error contracts are not shown in the README excerpt.

Alternatives

Use Juejin’s APIs directly from your own backend with proper OAuth/session handling Create a generic MCP tool that calls your own “content publishing” service (where auth, rate limiting, and logging are handled centrally) Use a different MCP server implementation with documented error handling and safer auth flows
