Manage & Operate
Manage tools
Enable, disable, and configure tool rules across your MCP servers.
Tools are the building blocks of your MCP server. Each tool represents one operation that an AI agent can invoke. This guide covers how to manage tools across both generated and connected servers.
Tool states#
| State | Meaning |
|---|---|
| Enabled | Visible to agents and included in generated server code |
| Disabled | Hidden from agents and excluded from generation |
| Removed from source | The endpoint disappeared during a refresh — automatically disabled but preserved for history |
Editing tool rules (generated servers)#
Generated servers have managed tools with editable rule fields:
- Open the server's Tools tab
- Click a tool to expand its editor
- Edit any combination of:
- Description override — replaces the OpenAPI description
- Instructions — general guidance for the AI
- When to use — helps the AI decide when to pick this tool
- When not to use — helps the AI avoid picking this tool incorrectly
- Examples — sample invocations as JSON
See Edit tool rules for details on each field and how they compose.
Bulk operations#
You can enable or disable multiple tools at once, or apply rules in batch, from the Tools tab. Select multiple tools and use the bulk actions bar.
Connected server tools#
Connected server tools are observed from the live server and are read-only by default. You can optionally customize the display name and description to improve agent tool selection, but other rule fields are not available because the upstream MCP server owns the tool contract.
Semantic tool selection#
Agenetix uses vector embeddings to match user messages to relevant tools. Embeddings regenerate automatically when you change a tool's description, instructions, or selection guidance. Better tool rules lead to more accurate tool selection by agents.
