Implementation Reference

• src/handlers/pipelines.ts:74-85 (handler)

  The handler function that executes the retry_pipeline tool by posting to the GitLab API endpoint to retry the specified pipeline and returns the result as JSON.

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

• src/tools/pipelines.ts:122-139 (schema)

  The tool schema definition including name, description, and input schema for the retry_pipeline tool.

  {
    name: 'retry_pipeline',
    description: 'Retry a failed 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/server.ts:299-302 (registration)

  The switch case that registers and dispatches calls to the retry_pipeline handler in the MCP server's tool request handler.

  case "retry_pipeline":
    return await this.pipelineHandlers.retryPipeline(
      args as unknown as PipelineActionParams
    );
