Implementation Reference

• src/index.ts:460-482 (handler)

  The handler logic for the 'delete_json_doc_from_db' tool. It validates input using DeleteJsonDocFromDbArgsSchema, ensures the database exists (creating if necessary), deletes the document by ID using db.del(), and returns a success message.

  case "delete_json_doc_from_db": {
    const parsed = DeleteJsonDocFromDbArgsSchema.safeParse(args);
    if (!parsed.success) {
      throw new Error(`Invalid arguments for delete_json_doc_from_db: ${parsed.error}`);
    }
  
    const dbName = parsed.data.databaseName;
    if (!dbs[dbName]) {
      const newDb = fireproof(dbName);
      dbs[dbName] = { db: newDb };
    }
    const db = dbs[dbName].db;
  
    await db.del(parsed.data.id);
    return {
      content: [
        {
          type: "text",
          text: `Deleted document with ID: ${parsed.data.id}`,
        },
      ],
    };
  }

• src/index.ts:88-91 (schema)

  Zod schema defining the input arguments for the delete_json_doc_from_db tool: databaseName (string) and id (string). Used for validation in the handler.

  const DeleteJsonDocFromDbArgsSchema = z.object({
    databaseName: z.string(),
    id: z.string(),
  });

• src/index.ts:172-188 (registration)

  Tool registration in the ListTools response, specifying name, description, and input schema (JSON Schema object).

  {
    name: "delete_json_doc_from_db",
    description: "Delete a JSON document by ID from a document database",
    inputSchema: {
      type: "object",
      properties: {
        id: {
          type: "string",
          description: "ID of document to delete",
        },
        databaseName: {
          type: "string",
          description: "name of document database to delete from",
        },
      }
    },
  },

• src/index.ts:176-186 (schema)

  JSON Schema in the tool registration for input validation, matching the Zod schema structure.

  type: "object",
  properties: {
    id: {
      type: "string",
      description: "ID of document to delete",
    },
    databaseName: {
      type: "string",
      description: "name of document database to delete from",
    },
  }
