Implementation Reference

• src/handlers/pipelines.ts:40-51 (handler)

  The main handler function that executes the get_pipeline tool by fetching pipeline details from the GitLab API using the provided project_id and pipeline_id, then returning the JSON response.

  async getPipeline(args: GetPipelineParams) {
    const data = await this.client.get(`/projects/${encodeURIComponent(args.project_id)}/pipelines/${args.pipeline_id}`);
    
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(data, null, 2),
        },
      ],
    };
  }

• src/tools/pipelines.ts:69-86 (registration)

  MCP tool registration in the pipelineTools array, defining the tool name, description, and input schema.

  {
    name: 'get_pipeline',
    description: 'Get details of a specific pipeline',
    inputSchema: {
      type: 'object',
      properties: {
        project_id: {
          type: 'string',
          description: 'Project ID or path',
        },
        pipeline_id: {
          type: 'number',
          description: 'Pipeline ID',
        },
      },
      required: ['project_id', 'pipeline_id'],
    },
  },

• src/types.ts:362-365 (schema)

  TypeScript interface defining the input parameters (project_id and pipeline_id) used by the get_pipeline handler.

  export interface GetPipelineParams {
    project_id: string;
    pipeline_id: number;
  }
