PostMD MCP Server

Model Context Protocol server for PostMD — publish a Markdown document, get a web page you share by link. Optional groups, document passwords, and viewer themes. This server wraps PostMD's public API (/api/v1) so assistants can publish, read, update and organize documents.

Publishing needs no account and no key. With zero configuration this server can already turn Markdown into a shareable page, and the hosted server at https://postmd.turink.com/mcp needs no install either. An API key adds management: organizing documents in groups, and notes.

30-day retention. Documents have a 30-day retention period (data.retainedUntil) that extends by 30 days whenever the document is read (at most once per day). Documents without a password can be updated or deleted by anyone; password-protected documents require the password or the owner's API key.

HTTP reference: postmd.turink.com/docs/api · machine-readable spec at /api-docs

Hosted or local

The hosted server has no way to receive an API key, so it carries only the tools that need none. Groups, notes and the tools that read a file from your disk are local-only.

Configuration

Local only — the hosted server reads none of these. All are optional.

Load order: this repo's .env (if present) is applied via dotenv without overwriting variables already set by the host (e.g. MCP env). Do not commit .env or keys.

Tools

Every tool below works on the local server. The hosted server carries five of them: postmdcreatedocument, postmdgetdocument, postmdgetdocumentraw, postmdupdatedocument, and postmddelete_document.

Publishing and reading — no key needed:

Managing documents — key with documents:write (or password / no credential for unowned documents without password):

Replacing content on a document that has notes

Notes are located by the text they quote, not by a stored position. Replacing a document's body therefore moves or loses where they point: a note whose quote is gone loses its place in the body, and one whose quote now appears elsewhere points there instead. The note itself, including the quoted text, is kept either way.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
