What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http writespace https://app.writespace.io/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "writespace": {
      "url": "https://app.writespace.io/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Writespace MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Writespace MCP Server

A remote, hosted Model Context Protocol server for Writespace — a real-time collaborative document editor. Give Claude, ChatGPT, Gemini, Cursor, or any MCP-speaking agent a shared docs workspace it can read, write, organise and search alongside you.

Endpoint: https://app.writespace.io/mcp (HTTP transport, Bearer auth) Free tier: yes — up to 10 documents, no card required → sign up

What it does

Writespace is a markdown-first doc editor for humans with an MCP server built in for agents. Every action you can take in the app is exposed as a tool your model can call:

Read — walk the workspace tree, fetch any doc as lossless JSON _or_ markdown, run ranked full-text search (drop it straight into your agent as RAG retrieval)
Write — create docs, append content, replace a single section by its heading, shallow-merge structured metadata
Organise — create/rename/move folders, move docs, query docs by metadata ({ status: "accepted" })

Agent writes broadcast over Realtime, so open editors reload live. Humans and agents work on the same canvas — no export step, no format negotiation.

Quick start

Three steps, two minutes:

Get a token — sign in at app.writespace.io, open Settings → API tokens, create a token (shown once, revocable any time).
Endpoint — one hosted endpoint for all accounts: https://app.writespace.io/mcp
Configure your client — snippets below.

Claude Code (CLI)

claude mcp add --transport http writespace \

https://app.writespace.io/mcp \ --header "Authorization: Bearer ws_pat_YOUR_TOKEN_HERE"

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json

Claude Desktop's config supports only local (stdio) servers, so a remote HTTP server is bridged through mcp-remote, which Claude Desktop launches locally and which forwards to the endpoint:

"mcpServers": { "writespace": { "command": "npx", "args": [ "-y", "mcp-remote", "https://app.writespace.io/mcp", "--header", "Authorization:${AUTH_HEADER}" ], "env": { "AUTH_HEADER": "Bearer ws_pat_YOUR_TOKEN_HERE" } } } }

Notes:

The token goes in the AUTH_HEADER env var (and --header Authorization:${AUTH_HEADER} with no space after the colon) because mcp-remote mishandles spaces in --header arguments.
Claude Desktop launches with a minimal PATH. If npx isn't found, use its absolute path (e.g. /usr/local/bin/npx, or your nvm path) — and add a matching "PATH" entry to env if it relies on a versioned node.
Fully quit and reopen Claude Desktop (Cmd-Q) after editing — the config is read only at launch.

Cursor

Settings → MCP → Add server

Type:    HTTP

URL: https://app.writespace.io/mcp Header: Authorization: Bearer ws_pat_YOUR_TOKEN_HERE

Gemini CLI

~/.gemini/settings.json

"mcpServers": { "writespace": { "httpUrl": "https://app.writespace.io/mcp", "headers": { "Authorization": "Bearer ws_pat_YOUR_TOKEN_HERE" } } } }

Any other spec-compliant MCP client works the same way: HTTP transport + Authorization: Bearer header.

Tools

Every tool except list_workspaces takes a workspace_id — call list_workspaces first to discover them.

Tool	Description
`list_workspaces`	List every workspace you belong to
`list_folders`	List folders, optionally nested under a parent
`list_docs`	List documents, optionally scoped to a folder; returns metadata per row
`get_doc`	Fetch a doc by ID — canonical Tiptap JSON + markdown rendering + metadata
`search`	Ranked full-text search with `< >` snippets
`query_docs`	Find docs whose metadata contains a JSON object (Postgres JSONB `@>`)
`create_doc`	Create a doc from Tiptap JSON or markdown
`update_doc`	Update title, content, or metadata (shallow-merge; `null` deletes a key)
`upsert_doc`	Create-or-update by title within an optional folder — idempotent
`append_to_doc`	Append markdown / Tiptap JSON to an existing doc
`replace_section`	Replace a section's body by its heading text — surgical edits
`delete_doc`	Delete a doc by ID
`move_doc`	Move a doc to another folder (`folder_id: null` → root)
`create_folder`	Create a folder, optionally nested
`rename_folder`	Rename a folder — IDs stay stable, links don't break
`delete_folder`	Delete a folder and its contents

Design notes

Lossless content, two formats — reads return both content (Tiptap JSON) and content_markdown; writes accept either. Markdown round-trips for everything the editor supports, including tables, task lists, and mermaid diagrams.
Lean write responses — write tools return only metadata by default, saving 80–95% of the payload on long docs. Pass include_content: true to echo the body.
Structured metadata — every doc carries a JSONB metadata field. Treat it as queryable frontmatter: write it, shallow-merge it, query by containment.
Stable cross-doc links — reference docs as writespace://doc/ ; IDs survive renames and moves.
Live reload — MCP writes notify open editors over Realtime; they refetch in the same tab.

Use cases

MCP docs server — a docs backend your agents treat as a tool
Shared docs for Claude — persistent memory and notes for Claude
Shared docs for ChatGPT — same workspace, different model
MCP knowledge base — searchable team knowledge any agent can query

Auth & security

Per-agent personal access tokens, issued and revoked from Settings — scoped to your account, easy to rotate
Tokens are shown once at creation
Standard Authorization: Bearer ws_pat_… header; spec-compliant HTTP transport
