• src/handlers/pipelines.ts:100-111 (handler)

  The core handler function that performs the DELETE request to the GitLab API to delete the specified pipeline and returns a success message or the response data.

  async deletePipeline(args: PipelineActionParams) {
    const response = await this.client.delete(`/projects/${encodeURIComponent(args.project_id)}/pipelines/${args.pipeline_id}`);
    
    return {
      content: [
        {
          type: 'text',
          text: response.status === 204 ? 'Pipeline deleted successfully' : JSON.stringify(response.data, null, 2),
        },
      ],
    };
  }

• src/tools/pipelines.ts:158-175 (schema)

  Tool schema definition including name, description, and input schema for validating arguments (project_id and pipeline_id).

  {
    name: 'delete_pipeline',
    description: 'Delete a pipeline',
    inputSchema: {
      type: 'object',
      properties: {
        project_id: {
          type: 'string',

        },
      },
      required: ['project_id', 'pipeline_id'],
    },

• src/server.ts:307-309 (registration)

  Registration in the tool dispatch switch statement that maps the 'delete_pipeline' tool name to the handler method call.

      args as unknown as PipelineActionParams

• src/server.ts:141-143 (registration)
