Implementation Reference
- src/index.ts:210-230 (handler)The async handler function that connects to the MongoDB database, gets the collection, and executes deleteOne or deleteMany based on the deleteMany parameter, returning the number of deleted documents.async ({ database: dbName, collection: collectionName, filter, deleteMany = false }) => { try { const db = await ensureConnection(dbName); const collection: Collection = db.collection(collectionName); const result = deleteMany ? await collection.deleteMany(filter) : await collection.deleteOne(filter); return { content: [ { type: "text", text: `Delete operation completed. Deleted ${result.deletedCount} document(s)`, }, ], }; } catch (error) { throw new Error(`Failed to delete document(s): ${error instanceof Error ? error.message : 'Unknown error'}`); } }
- src/index.ts:204-209 (schema)Zod schema defining the input parameters: database, collection, filter (required), and optional deleteMany flag.{ database: z.string().describe("Database name"), collection: z.string().describe("Collection name"), filter: z.record(z.any()).describe("Query filter to match documents to delete"), deleteMany: z.boolean().optional().describe("Whether to delete multiple documents (default: false)"), },
- src/index.ts:201-231 (registration)The server.tool() call that registers the 'mongo-delete-document' tool with its description, input schema, and handler function.server.tool( "mongo-delete-document", "Delete documents from a MongoDB collection", { database: z.string().describe("Database name"), collection: z.string().describe("Collection name"), filter: z.record(z.any()).describe("Query filter to match documents to delete"), deleteMany: z.boolean().optional().describe("Whether to delete multiple documents (default: false)"), }, async ({ database: dbName, collection: collectionName, filter, deleteMany = false }) => { try { const db = await ensureConnection(dbName); const collection: Collection = db.collection(collectionName); const result = deleteMany ? await collection.deleteMany(filter) : await collection.deleteOne(filter); return { content: [ { type: "text", text: `Delete operation completed. Deleted ${result.deletedCount} document(s)`, }, ], }; } catch (error) { throw new Error(`Failed to delete document(s): ${error instanceof Error ? error.message : 'Unknown error'}`); } } );
