An MCP server that brings ServiceNow Fluent SDK capabilities to AI-assisted development environments. Enables natural language interaction with ServiceNow SDK commands, API specifications, code snippets, and development resources.
- 🤖 AI-Powered Error Analysis - Intelligent diagnosis with root cause, solutions, and prevention tips (MCP Sampling)
- Complete SDK Coverage - All ServiceNow SDK commands:
auth,init,build,install,dependencies,transform,download,clean,pack - Rich Resources - API specifications, code snippets, instructions for 35+ metadata types
- Multi-Environment Auth - Supports
basicandoauthauthentication with profile management - Session-Aware - Maintains working directory context across commands
This MCP server implements the complete Model Context Protocol specification with the following capabilities:
- Resources - Provides 100+ resources across 35+ ServiceNow metadata types (API specs, instructions, snippets, prompts)
- Tools - Exposes 10 ServiceNow SDK commands as MCP tools with full parameter validation
- Prompts - Offers development workflow templates for common ServiceNow tasks
- Roots - Supports MCP roots protocol for workspace-aware operations
-
Sampling (MCP 2024-11-05) - Leverages client LLM for intelligent error analysis when SDK commands fail
- Automatically analyzes command errors >50 characters
- Provides structured diagnostics: root cause, solutions, prevention tips
- Configurable via
FLUENT_MCP_ENABLE_ERROR_ANALYSISenvironment variable
-
Elicitation (MCP 2024-11-05) - Interactive parameter collection for complex workflows
init_fluent_app- Prompts for missing project parameters (workingDirectory, template, appName, etc.)- Supports both creation and conversion workflows with smart validation
- Handles user acceptance/rejection of elicited data
-
Session Management - Tracks working directory per session for multi-project workflows
-
Root Fallback - Automatically falls back to MCP root context when no session directory is set
-
Error Handling - Comprehensive error messages with actionable guidance
-
Type Safety - Full TypeScript implementation with strict typing

Environment Variables:
SN_INSTANCE_URL- ServiceNow instance URL (optional, can use auth profiles instead)SN_AUTH_TYPE- Authentication method:basicoroauth(optional)FLUENT_MCP_ENABLE_ERROR_ANALYSIS- Enable AI error analysis (default:true)FLUENT_MCP_MIN_ERROR_LENGTH- Minimum error length for analysis (default:50)
-
Setup Authentication
Create a new auth profile for https://dev12345.service-now.com with alias dev-instance -
Initialize Project
Create a new Fluent app in ~/projects/asset-tracker for IT asset management -
Develop with Resources
Show me the business-rule API specification and provide an example snippet -
Build and Deploy
Build the app with debug output, then deploy to dev-instance
The MCP Inspector provides a web interface for testing MCP servers.
# Test published package
npx @modelcontextprotocol/inspector npx @modesty/fluent-mcp
# Or for local development
npm run build && npm run inspectObjective: Access API specs and code snippets for business rules
Steps:
- Launch Inspector and wait for server connection
- Navigate to Resources tab
- Find and click
sn-spec://business-rulein the resource list - Review the API specification showing all available methods and parameters
- Go back and search for
sn-snippet://business-rule/0001 - Click the snippet to view a complete TypeScript example
- Verify content includes proper imports and follows Fluent patterns
Expected Results:
- API spec displays structured documentation with method signatures
- Snippet shows runnable TypeScript code with ServiceNow metadata patterns
- Content is properly formatted and readable
Objective: Verify SDK version and help information retrieval
Steps:
- Navigate to Tools tab
- Select
sdk_infofrom the tool list - Test Version:
- Set
flagparameter to-v - Click Execute
- Verify response shows version number (e.g., "4.0.1")
- Set
- Test Help:
- Set
flagparameter to-h - Set
commandparameter tobuild - Click Execute
- Verify response shows build command documentation with options
- Set
- Monitor Notifications pane for command execution logs
Expected Results:
- Version command returns SDK version string
- Help command returns detailed command documentation
- No errors in notifications pane
- Commands execute within 2-3 seconds
