SAP Fieldglass MCP server

SAP Fieldglass is a cloud-based Vendor Management System (VMS) and services procurement platform helping organizations manage external workforce including contingent workers, statement of work (SOW) engagements, and vendor relationships. With this MCP server, AI agents can manage requisitions, track candidates and workers, process timesheets, manage invoices, and access workforce analytics through natural language commands.

Setting up an MCP server

This article covers the standard steps for creating an MCP server in AI Gateway and connecting it to an AI client. The steps are the same for every integration — application-specific details (API credentials, OAuth endpoints, and scopes) are covered in the Authentication section on this page.

Before you begin

You'll need:

• Access to AI Gateway with permission to create MCP servers.
• API credentials for the application you're connecting (see the Authentication section on this page for what to collect).

Create an MCP server

Find the app in the catalog

1. Sign in to AI Gateway and select App Catalog from the left navigation.
2. Search for the application you want to connect, then select it from the catalog.
3. Select Create MCP Server to start the wizard.

App Configuration

Confirm the Base URL for the API, then, under Tools, select the endpoints you want to expose. Select Next.

MCP Server Setup

1. Enter a Name for your server — something descriptive that identifies both the application and its purpose.
2. Enter a Description so your team knows what the server is for.
3. Set the log level: choose Production Mode for terser logs, or Non-Production Mode for more verbose logs that can help with debugging.
4. Select Next.

Authentication

Enter the authentication details for the application. This varies by service — see the Authentication section on this page for the specific credentials, OAuth URLs, and scopes to use.

Review

Look over the summary of your MCP server configuration, then select Create & Deploy. AI Gateway provisions the server and provides a server URL you'll use when configuring your AI client.

Connect to an AI client

Once your server is deployed, you'll need to add it to the AI client your team uses. Select your client for setup instructions:

• Claude Desktop
• Claude Code
• Cursor
• VS Code
• Windsurf

Tips

• You can create multiple MCP servers for the same application — for example, a read-only server for reporting agents and a read-write server for automation workflows.
• If you're unsure which OAuth scopes to request, start with the minimum read-only set and add write scopes only when needed. Most application pages include scope recommendations.

Authentication

SAP Fieldglass uses OAuth 2.0 authentication. Configure OAuth in your Fieldglass instance to obtain credentials. Replace {fieldglass-instance} with your actual Fieldglass instance URL. In Fieldglass, go to Admin > Integration > OAuth Clients to register your OAuth client and obtain credentials.

Value	Setting
Auth endpoint	https://{fieldglass-instance}/oauth/authorize
Token endpoint	https://{fieldglass-instance}/oauth/token

Available tools

The SAP Fieldglass MCP server exposes requisition management, candidate tracking, worker management, timesheet processing, invoicing, and workforce analytics APIs.

Tool	Purpose
Requisition Management	Create requisitions for contingent roles; post job openings; manage requisition status; track approvals
Candidate Management	Review candidate submissions; manage candidate pipelines; accept/reject candidates; extend offers
Worker Management	Onboard contingent workers; manage worker profiles; track worker assignments; manage off-boarding
Timesheet & Attendance	Process worker timesheets; track hours; manage approvals; handle exceptions and disputes
Invoice Processing	Process vendor invoices; track invoice status; reconcile invoices with timesheets; manage payments
Statement of Work (SOW)	Create SOW-based engagements; track deliverables; manage SOW projects; process completions
Vendor Management	Manage vendor profiles; track vendor performance; evaluate vendors; maintain vendor ratings
Analytics & Reporting	Generate workforce analytics; track spend by vendor; analyze staffing trends; forecast needs

Tips

Create clear job descriptions with specific requirements, set realistic budgets and timelines, route requisitions through approval workflows, and track time-to-fill metrics.

Maintain accurate vendor master data and evaluate vendors systematically while tracking vendor compliance and conducting regular performance reviews.

Ensure proper classification (W-2, 1099, etc.) for compliance, configure onboarding workflows, verify required documentation, and maintain audit trail.

Establish clear time tracking policies and review timesheets promptly for discrepancies while maintaining audit logs and reconciling with pay cycles.

Three-way match invoices with timesheets and POs, set up exception handling for variances, process payments promptly, and maintain vendor relationships.
