Install MCP servers in your Overcut workspace with one click using the MCP Catalog — a curated, open-source collection of pre-configured server definitions. Each catalog entry includes the server configuration, required secrets, and a recommended tool set, so you can go from discovery to a working integration without writing JSON by hand.
The catalog is powered by the open-source repository at overcut-ai/overcut-mcp-catalog. You can browse entries, suggest new servers, or contribute directly.

​
What is the MCP Catalog?

The MCP Catalog is an in-app gallery of MCP server definitions. Overcut fetches the catalog from the overcut-mcp-catalog GitHub repository and presents it as a searchable, filterable page inside your workspace.
MCP servers in the catalog are provided by third parties. Configurations, tool sets, and APIs may change as providers release new versions. Always review the server’s documentation and verify its authenticity before installing. Overcut does not guarantee the behavior, availability, or security of third-party MCP servers.
Each catalog entry defines:
  • Server configuration — the JSON config Overcut uses to connect (command + args or URL + headers)
  • Required secrets — credentials the server needs, with descriptions and help links
  • Recommended tools — a curated subset of tools suitable for most use cases
  • All tools — the full set of tools the server provides

Browse the Catalog

MCP Catalog in the Overcut workspace

Open the catalog

Navigate to MCP Servers in the sidebar and click Add MCP Server. This opens the catalog.

Search and filter

Use the search field to find servers by name or description. Use category filters to narrow results by use case (e.g. monitoring, design, documentation).

Check install status

Each catalog card shows its status: Installed if the server already exists in your workspace, or Install if it hasn’t been added yet.
If a server is already installed, you can go directly to assigning it to an agent. If not, click the card to start the guided install flow.

​
Install from the Catalog

Open the catalog entry

Click a catalog card to open its install page. You’ll see the server description, configuration preview, and setup inputs.

Provide required secrets

For each required credential, enter a new secret value or — if the same credential already exists in your Vault — it will be detected and attached automatically.

Choose allowed tools

Use the All Tools toggle to grant every tool, or leave it off to use per-tool checkboxes. Tools default to the catalog’s recommended set — toggle individual tools on or off as needed.

Review the configuration

The install page shows a read-only preview of the server’s JSON configuration. Verify it looks correct before proceeding.

Install

Click Install MCP Server. Overcut creates the server and redirects you to its detail page so you can verify the setup immediately.
Reuse existing Vault secrets whenever possible. This keeps credentials consistent across MCP servers and simplifies future rotation.

​
Split a Server Across Agents

You can install the same MCP server multiple times with different tool sets and assign each instance to different agents. This gives you fine-grained control over what each agent can do. Common patterns:
  • Scoped access — give a read-only Datadog instance to a triage agent (only log query tools) and a full-access instance to an incident responder (query + alert management tools)
  • Project isolation — install the same Sentry server twice with different API keys so two agents monitor different projects independently
  • Least privilege — limit each agent to only the tools it actually needs, reducing the risk of unintended actions
Keeping the tool set small helps the agent stay focused. Too many tools can slow down execution and lead to less accurate results. When in doubt, start with the recommended tools and add more only as needed.

​
Add a Custom Server

If the server you need isn’t in the catalog, click Add Custom in the top-right corner of the catalog page. This creates a blank MCP server entry and opens its detail page, where you can configure it manually. See the MCP Servers reference for the full manual setup flow.

​
Contribute to the Catalog

The catalog is open source at overcut-ai/overcut-mcp-catalog. Each server is defined as a directory containing a catalog.json file.

Catalog entry schema

Each catalog.json follows this structure: 
{
  "name": "Sentry",
  "description": "Search errors, investigate issues...",
  "category": "monitoring",
  "tags": ["errors", "debugging"],
  "iconUrl": "https://raw.githubusercontent.com/.../icon.svg",
  "websiteUrl": "https://github.com/getsentry/sentry-mcp",
  "priority": 10,

  "serverConfig": {
    "command": "npx",
    "args": ["-y", "@sentry/mcp-server@latest"],
    "env": {
      "SENTRY_ACCESS_TOKEN": "${SENTRY_ACCESS_TOKEN}"
    }
  },

  "requiredSecrets": [
    {
      "envVar": "SENTRY_ACCESS_TOKEN",
      "displayName": "Sentry Access Token",
      "description": "Create an Internal Integration token...",
      "helpUrl": "https://docs.sentry.io/..."
    }
  ],

  "recommendedTools": ["search_issues", "get_issue_details"],
  "allTools": ["search_issues", "get_issue_details", "create_issue", "..."]
}
See the CONTRIBUTING.md for full guidelines on adding new entries.

​
Create entries with AI

The catalog repository ships with built-in rules for popular AI coding tools (Claude Code, Cursor, Codex, Gemini). Clone it and use your preferred agent to generate new catalog entries: 
git clone https://github.com/overcut-ai/overcut-mcp-catalog.git
Ask your AI agent to create a new entry — it understands the catalog schema, secret conventions, and tool discovery patterns automatically.
