​
Overview

Wirebase is an MCP client. Any remote server that speaks the Model Context Protocol can be added as a connector, and its tools become available in chat, agents and workflows.

​
Requirements

​
Authentication

Choose one:
Accept a token in a header, typically Authorization: Bearer <token>. The person adding the connector enters it under Headers.

​
Tool naming

Tools appear in Wirebase as <connector>_<tool>, for example github_create_issue. Names are sanitized to letters, numbers, underscores and hyphens and capped at 124 characters. Keep tool names short and descriptive.

​
Write tools that models use well

  • Describe when to use the tool, not just what it does. The description is what the model reads when deciding.
  • Keep input schemas small and typed. Use enums for fixed choices and mark required fields.
  • Return compact results. Tool output is truncated at about 40,000 characters before it reaches the model. Return the fields that matter, and paginate large lists.
  • Return clear errors. A short, specific error message lets the model correct itself and retry.
Admins can add per-tool and per-connector custom instructions to steer usage without changing your server.

​
Test your server

Add it under Workspace → Connectors → Add custom connector, open it, and use Tools Test to call each tool with sample input before using it in chat.
