Flipt MCP Server

Implementation Reference

• src/index.ts:816-840 (handler)

  The MCP tool handler function that invokes the fliptClient to delete the constraint and formats the success or error response.

  async args => {
    try {
      await fliptClient.deleteConstraint(args.namespaceKey, args.segmentKey, args.constraintId);
  
      return {
        content: [
          {
            type: 'text',
            text: `Successfully deleted constraint ${args.constraintId} from segment ${args.segmentKey}`,
          },
        ],
      };
    } catch (error: any) {
      console.error('Error deleting constraint:', error);
      return {
        content: [
          {
            type: 'text',
            text: `Failed to delete constraint: ${error.message}`,
          },
        ],
        isError: true,
      };
    }
  }

• src/index.ts:811-815 (schema)

  Zod input schema defining parameters for the delete_constraint tool: namespaceKey, segmentKey, and constraintId.

  {
    namespaceKey: z.string().min(1),
    segmentKey: z.string().min(1),
    constraintId: z.string().min(1),
  },

• src/index.ts:809-841 (registration)

  Registration of the delete_constraint tool using server.tool with name, schema, and handler function.

  server.tool(
    'delete_constraint',
    {
      namespaceKey: z.string().min(1),
      segmentKey: z.string().min(1),
      constraintId: z.string().min(1),
    },
    async args => {
      try {
        await fliptClient.deleteConstraint(args.namespaceKey, args.segmentKey, args.constraintId);
  
        return {
          content: [
            {
              type: 'text',
              text: `Successfully deleted constraint ${args.constraintId} from segment ${args.segmentKey}`,
            },
          ],
        };
      } catch (error: any) {
        console.error('Error deleting constraint:', error);
        return {
          content: [
            {
              type: 'text',
              text: `Failed to delete constraint: ${error.message}`,
            },
          ],
          isError: true,
        };
      }
    }
  );

• src/services/fliptClient.ts:519-527 (helper)

  Helper method in FliptClient that calls the generated API to delete the constraint.

  async deleteConstraint(namespaceKey: string, segmentKey: string, id: string) {
    try {
      await this.constraintsApi.deleteConstraint(namespaceKey, segmentKey, id);
      return { success: true };
    } catch (error) {
      console.error('Error deleting constraint:', error);
      throw error;
    }
  }
