# guMCP Servers

> Pre-built MCP integrations managed by Gumloop

guMCP servers are pre-built, managed MCP integrations for popular tools and services. They're maintained by Gumloop and ready to use out of the box, no code or deployment required.

</Frame>

## Browsing servers

The guMCP page shows a searchable table of all available integrations. Each server lists its **name** and **category** (e.g., CRM, Analytics, Development, Communication). New servers are added regularly.

Some servers have credential requirements:

* **Required credentials**: Secrets the user must provide to authenticate (e.g., API key)
* **Optional credentials**: Additional credentials that unlock extra functionality

## Server detail

Click any guMCP server to see its detail page with **3 tabs**: Overview, Activity, and Tools & Access.

<Info>
  guMCP servers don't have Deployments or Settings tabs since they're fully managed by Gumloop. You only configure tool-level access for your organization.
</Info>

### Overview

<Frame>
  <img src="https://mintcdn.com/gumstack/RGOCNHwGb3PE0tCf/images/platform/gumcp-server-detail-overview.png?fit=max&auto=format&n=RGOCNHwGb3PE0tCf&q=85&s=c97a5a73bab80c6dc8e3264e1e822a09" alt="guMCP server detail overview" width="3024" height="1722" data-path="images/platform/gumcp-server-detail-overview.png" />
</Frame>

The overview shows 4 stat cards (7-day data): Total Calls, Unique Users, Error Rate, and Avg Latency, followed by the 10 most recent tool calls with expandable rows for input/output details.

### Activity

<Frame>

</Frame>

Server-scoped activity log with histogram (stacked by status), full tool call table with expandable rows, filters (Status, Tool, User, Date Range), and CSV export. Same interface as the [global Activity page](/platform/activity).

### Tools & Access

Control which [permission groups](/platform/permission-groups) can use which tools on this server.

</Frame>

The matrix shows tools as rows with type badges (W = Write, D = Delete, R = Read), permission groups as columns, and checkboxes for toggling access. The header summarizes "X groups, Y users, Z tools".

<Steps>
  <Step title="Navigate to the server">
    Find the guMCP server in the list and click to open its detail page.
  </Step>

  <Step title="Go to Tools & Access">
    Click the **Tools & Access** tab to see the permission matrix.
  </Step>

  <Step title="Toggle access and save">
    Click checkboxes to enable or disable tool access per group. A floating action bar appears with **Save Changes** and **Discard Changes**. Click Save to apply.
  </Step>
</Steps>

<Warning>
  Changes to tool access take effect immediately after saving. New calls from a revoked group will be denied and logged as "Permission Denied" in the [Activity](/platform/activity) dashboard.
</Warning>

## guMCP vs Internal servers

| Feature                 | guMCP Servers                      | Internal Servers                                 |
| ----------------------- | ---------------------------------- | ------------------------------------------------ |
| **Managed by**          | Gumloop                            | Your team                                        |
| **Code required**       | No                                 | Yes                                              |
| **Deployment**          | Automatic (by Gumloop)             | Push-to-deploy via GitHub                        |
| **Tabs**                | Overview, Activity, Tools & Access | Overview, Tools, Activity, Deployments, Settings |
| **Tool access control** | Yes                                | Yes                                              |
| **Customization**       | Tool access only                   | Full control over code, auth, tools, env vars    |

<Tip>
  guMCP servers are the fastest way to get started. If you need a custom integration that isn't available, [build your own internal server](/building/quickstart).
