Implementation Reference
- src/tools/describe.ts:19-40 (handler)The handler function that executes the Salesforce describeGlobal operation, formatting the object metadata into a readable text response.export async function handleDescribeObject(conn: any, objectName: string) { const describe = await conn.describe(objectName) as SalesforceDescribeResponse; // Format the output const formattedDescription = ` Object: ${describe.name} (${describe.label})${describe.custom ? ' (Custom Object)' : ''} Fields: ${describe.fields.map((field: SalesforceField) => ` - ${field.name} (${field.label}) Type: ${field.type}${field.length ? `, Length: ${field.length}` : ''} Required: ${!field.nillable} ${field.referenceTo && field.referenceTo.length > 0 ? `References: ${field.referenceTo.join(', ')}` : ''} ${field.picklistValues && field.picklistValues.length > 0 ? `Picklist Values: ${field.picklistValues.map((v: { value: string }) => v.value).join(', ')}` : ''}` ).join('\n')}`; return { content: [{ type: "text", text: formattedDescription }], isError: false, }; }
- src/tools/describe.ts:4-17 (schema)The tool schema defining name, description, and input parameters (objectName).export const DESCRIBE_OBJECT: Tool = { name: "salesforce_describe_object", description: "Get detailed schema metadata including all fields, relationships, and field properties of any Salesforce object. Examples: 'Account' shows all Account fields including custom fields; 'Case' shows all Case fields including relationships to Account, Contact etc.", inputSchema: { type: "object", properties: { objectName: { type: "string", description: "API name of the object (e.g., 'Account', 'Contact', 'Custom_Object__c')" } }, required: ["objectName"] } };
- src/index.ts:61-65 (registration)Registration in the tool call handler switch statement that invokes the handleDescribeObject function.case "salesforce_describe_object": { const { objectName } = args as { objectName: string }; if (!objectName) throw new Error('objectName is required'); return await handleDescribeObject(conn, objectName); }
- src/index.ts:35-45 (registration)Registration in the listTools handler where DESCRIBE_OBJECT is included in the available tools list.server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: [ SEARCH_OBJECTS, DESCRIBE_OBJECT, QUERY_RECORDS, DML_RECORDS, MANAGE_OBJECT, MANAGE_FIELD, SEARCH_ALL ], }));
