Marcora MCP Server

The Marcora MCP Server exposes all of your Marcora tools directly inside AI assistants like Claude and ChatGPT, letting you create blueprints, generate content, manage context, and more — without leaving your AI chat.

Connection URL

https://mcp.marcora.ai

This is the single URL for connecting to the Marcora MCP Server. It works both with OAuth — ideal for Claude and ChatGPT — and with a direct API key or token, supplied as the bearer. Transport is negotiated automatically (Streamable HTTP, with SSE fallback), so the same URL works across MCP clients.

You can create and manage your MCP API keys in Integrations Settings — then use your API key with the URL above.

Connecting in Claude

Marcora is listed in Claude's connector directory, so there's no URL and no token to paste. That's fewer steps than adding it by hand — not zero: you still approve access, and Claude asks permission the first time it uses each tool.

  1. Open the Marcora listing in Claude's connector directory.
  2. Click Connect. Marcora's authorization page opens — click Allow. (If you already have MCP tokens, you'll be asked which one to use first.) Claude returns you to a new chat.
  3. Just ask. Marcora is already switched on in every new conversation — there is nothing to enable in the composer. Try: "What's my brand foundation?"
  4. Approve the tool the first time Claude reaches for it. Claude pauses and asks — "Claude wants to use Get Brand Foundation from Marcora: Brand Context & Writing" — with Always allow and Deny. Click Always allow.

⚠️ Step 4 is the one people miss. Until you click Always allow, nothing reaches Marcora: Claude will have found the tools but never actually called one. The prompt is per tool, not per connector, so expect it again the first time each new Marcora tool comes up. Approvals then persist across all your conversations. (Allow once, under the small chevron, approves a single call and asks again next time.)

Claude labels Marcora a Community connector, meaning it passed Anthropic's automated checks rather than their in-depth review. That describes how the listing was assessed — it doesn't limit what Marcora can do once you connect it.

Managing the connection later: go to Customize → Connectors (claude.ai/customize/connectors), where Marcora appears as Connected. Note that it only shows up in that list after you connect — searching for it there beforehand returns nothing, which is why step 1 starts at the directory.

Adding Marcora by URL instead

The directory is a catalogue, not a different kind of connector — adding Marcora by URL gives you exactly the same tools. Use this route if you're adding Marcora for a whole Team or Enterprise workspace, or if you'd simply rather paste the URL.

  1. In Claude, go to Customize → Connectors, click Add, then choose Add custom connector.
  2. Give the connector a name and paste your Marcora MCP Server URL: https://mcp.marcora.ai
  3. Click Add, then click Connect next to "Marcora" and approve access to finish the OAuth flow.

Then carry on from step 3 above — the per-tool approval prompt works the same way.

On the Free Claude plan you can have only one custom connector. Connecting from the directory doesn't involve adding a custom connector at all, so it leaves that slot free.

Connecting in ChatGPT

  1. Open ChatGPT's Advanced Settings.
  2. Turn Developer mode on, then click Create app.
  3. When prompted, enter your Marcora MCP Server URL: https://mcp.marcora.ai

To use it in a chat: start a conversation, open the Developer mode tool picker, and select the Marcora app to enable its tools.

The Marcora AI Workflows Anthropic Skill ships alongside this server. It teaches your AI client Marcora's mental model and the right patterns for every task — the object model, content generation, blueprints, projects, briefs, context items, the content plans board and playbooks, and building reusable multi-step workflows — so the agent stops misfiring on tasks that look ambiguous from tool descriptions alone.

  • Marcora AI Workflows (marcora-mcp, v0.7.3) — object model (content, blueprints, projects, context items), content-generation patterns, the 4-layer context model, project-brief mechanics, the content plans board and playbooks, and building reusable multi-step workflows. Your AI client picks it up on demand based on the task.

Download

Get the .skill file from the latest release:

  • marcora-mcp.skill — the Marcora skill (a zip archive containing SKILL.md and its bundled reference files).

Install

Claude Code:

mkdir -p ~/.claude/skills
unzip ~/Downloads/marcora-mcp.skill -d ~/.claude/skills/

Restart Claude Code. The skill loads automatically on any Marcora-related task.

Claude Desktop:

Import the .skill file via Claude Desktop's Skills folder. See Anthropic's Skills documentation for the current path on your platform.

ChatGPT, Cursor, and other non-Anthropic clients:

These don't directly support Anthropic Skills (yet). Workaround: unzip the .skill file and paste the contents of SKILL.md into your client's custom instructions or system-prompt slot. Bundled reference files can be pasted in too if your client supports longer context.

If you'd rather track main directly:

git clone https://github.com/ccromp/marcora-mcp.git
ln -s "$(pwd)/marcora-mcp/skill/marcora-mcp" ~/.claude/skills/marcora-mcp

Releases

Releases are tagged marcora-vX.Y.Z — see Releases. Each release attaches the bundled skill as marcora-mcp.skill. The skill's own version is the metadata.version field in its SKILL.md, and it moves independently of the release tag.
