Linear MCP Server

Instructions

Implementation Reference

• src/index.ts:354-373 (handler)

  The switch case handler for the 'list_teams' tool. It fetches all teams from the Linear workspace using linearClient.teams(), formats the nodes into an array of objects with id, name, key, and description, and returns them as a JSON text content block.

  case "list_teams": {
    const query = await linearClient.teams();
    const teams = await Promise.all(
      (query as any).nodes.map(async (team: any) => ({
        id: team.id,
        name: team.name,
        key: team.key,
        description: team.description,
      }))
    );
  
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(teams, null, 2),
        },
      ],
    };
  }

• src/index.ts:161-168 (schema)

  Schema definition for the list_teams tool in the ListTools response, including name, description, and an empty input schema since no parameters are required.

  {
    name: "list_teams",
    description: "List all teams in the workspace",
    inputSchema: {
      type: "object",
      properties: {},
    },
  },

• src/index.ts:45-56 (registration)

  Registration of tool capabilities in the MCP server constructor, declaring support for the list_teams tool.

    capabilities: {
      tools: {
        create_issue: true,
        list_issues: true,
        update_issue: true,
        list_teams: true,
        list_projects: true,
        search_issues: true,
        get_issue: true,
      },
    },
  }
