# MCP Toolsets
|
||||
|
||||
A **Toolset** is a named collection of specific tools drawn from one or more MCP servers. Instead of giving an agent access to every tool on every server, you pick exactly which tools it needs — from whichever servers they live on — and bundle them under a single name.
|
||||
|
||||
## How it works
|
||||
|
||||
```
|
||||
┌─────────────────────────────────┐
|
||||
│ MCP Toolset │
|
||||
│ "devtooling-prod" │
|
||||
└────────────┬────────────────────┘
|
||||
│
|
||||
┌──────────────────┴──────────────────┐
|
||||
│ │
|
||||
┌────────▼────────┐ ┌────────▼────────┐
|
||||
│ CircleCI MCP │ │ DeepWiki MCP │
|
||||
│ (10+ tools) │ │ (3 tools) │
|
||||
└────────┬────────┘ └────────┬────────┘
|
||||
│ │
|
||||
┌─────────┴──────────┐ ┌──────────┴──────────┐
|
||||
│ ✓ get_build_logs │ │ ✓ read_wiki_structure│
|
||||
│ ✓ find_flaky_tests │ │ ✓ read_wiki_contents │
|
||||
│ ✓ get_pipeline_ │ │ ✗ ask_question │
|
||||
│ status │ └─────────────────────┘
|
||||
│ ✓ run_pipeline │
|
||||
│ ✗ list_followed_ │
|
||||
│ projects │
|
||||
└────────────────────┘
|
||||
|
||||
Agent sees exactly 6 tools, nothing more.
|
||||
```
|
||||
|
||||
Instead of 13+ tools across two servers, the agent gets 6 — the ones it actually needs.
|
||||
|
||||
**Why this matters:**
|
||||
- Smaller tool lists → fewer tokens, faster responses, less hallucination
|
||||
- Combine tools from GitHub + Linear + CircleCI into one named grant
|
||||
- Assign to keys and teams the same way you assign MCP servers today

|
||||
## Create a toolset
|
||||
|
||||
### 1. Go to the MCP page
|
||||
|
||||
Navigate to **MCP** in the left sidebar.
|
||||
|
||||
|
||||
|
||||
### 2. Open the Toolsets tab
|
||||
|
||||
Click the **Toolsets** tab on the MCP page.
|
||||
|
||||
|
||||
|
||||
### 3. Click "New Toolset"
|
||||
|
||||
|
||||
|
||||
### 4. Enter a name
|
||||
|
||||
Type a name for the toolset. Pick something descriptive — this is what agents will reference.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 5. Add the first tool
|
||||
|
||||
Select an MCP server from the dropdown, then choose the tool you want to include from that server.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 6. Add tools from a second server
|
||||
|
||||
Click **Add Tool**, pick a different MCP server, and select another tool. Repeat for as many tools as you need — they can come from any number of servers.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 7. Create the toolset
|
||||
|
||||
Click **Create Toolset** to save.
|
||||
|
||||
|
||||

||||

||||
## Use a toolset in the Playground
|
||||
|
||||
Once created, your toolset appears alongside MCP servers in the **MCP Servers** dropdown in the Playground — it's selectable the same way.
|
||||
|
||||
### 1. Go to the Playground
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 2. Select your toolset from MCP Servers
|
||||
|
||||
In the left panel under **MCP Servers**, open the dropdown and pick your toolset. The model will only see the tools you included in it.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
The model now has access to exactly the tools in your toolset and nothing else.
|
||||

|
||||
|
||||
## Use a toolset via API
|
||||
|
||||
Pass the toolset's route as the `server_url` in your tools list. LiteLLM resolves it server-side — no public URL needed.
