Implementation Reference

  • Handler function that ensures MongoDB connection, retrieves the collection, inserts the document using insertOne, and returns a success message with the inserted ID or throws an error.
    async ({ database: dbName, collection: collectionName, document }) => {
      try {
        const db = await ensureConnection(dbName);
        const collection: Collection = db.collection(collectionName);
        
        const result = await collection.insertOne(document);
        
        return {
          content: [
            {
              type: "text",
              text: `Document created successfully with ID: ${result.insertedId}`,
            },
          ],
        };
      } catch (error) {
        throw new Error(`Failed to create document: ${error instanceof Error ? error.message : 'Unknown error'}`);
      }
    }
  • Zod input schema defining the required parameters: database name, collection name, and document object.
    database: z.string().describe("Database name"),
    collection: z.string().describe("Collection name"),
    document: z.record(z.any()).describe("Document to insert as JSON object"),
  • src/index.ts:102-129 (registration)
    Registration of the 'mongo-create-document' tool using server.tool(), including name, description, input schema, and handler function.
    server.tool(
      "mongo-create-document",
      "Create a new document in a MongoDB collection",
      {
        database: z.string().describe("Database name"),
        collection: z.string().describe("Collection name"),
        document: z.record(z.any()).describe("Document to insert as JSON object"),
      },
      async ({ database: dbName, collection: collectionName, document }) => {
        try {
          const db = await ensureConnection(dbName);
          const collection: Collection = db.collection(collectionName);
          
          const result = await collection.insertOne(document);
          
          return {
            content: [
              {
                type: "text",
                text: `Document created successfully with ID: ${result.insertedId}`,
              },
            ],
          };
        } catch (error) {
          throw new Error(`Failed to create document: ${error instanceof Error ? error.message : 'Unknown error'}`);
        }
      }
    );
