Model Context Protocol (MCP)
MCP is an open protocol for connecting AI assistants such as Claude to tools and data. An application runs an MCP server that describes its tools; any MCP client can then call them.
It turns an application into something you can work with in plain language, without a separate integration for every assistant. Many vendors, Atlassian among them, ship their own MCP servers.
Updates
MCP is how we connect our tools to AI assistants. Our own applications run MCP servers: our controlling app, built on Drupal, exposes projects, planning, time, costs, statements of work and CVs, and Subtool, our tool for managing submissions for tenders by conversation, exposes its bids. Our Claude skills for estimates, statements of work and CVs build on them. We built further MCP servers with OAuth sign-in for IMAP mailboxes, Mattermost and Twenty CRM, and use the vendor servers for Jira and Confluence. One assistant can then search mail and draft replies, maintain CRM records, post to team channels and update tickets.
