First Steps
Once you have registered and authenticated the MCP server in Claude Code, start with project setup.
Recommended: Run Project Setup
The first thing to do after connecting is run the check_project_setup prompt. It automatically prepares the following for your project:
.history/directory: A place to accumulate knowledge gained during developmentCLAUDE.mdadditions: Rules for always using this MCP, plus knowledge-saving routines
The psm part is the name you specified when registering the server.
/mcp__psm__check_project_setupClaude will check the state of .history/ and CLAUDE.md, and automatically create or update them if anything is missing.
TIP
Once settings are written to CLAUDE.md, Claude will automatically reference .history/ in subsequent sessions and carry over your project knowledge.
Verify the Connection
After setup, use the project_start prompt to confirm everything is working:
/mcp__psm__project_startSuccessful Response
If the connection succeeds, Claude Code calls the MCP server and returns the prompt output:
Starting guide for new project ""
## Development Workflow Overview
A structured workflow for systematic software development.
Guides you step by step from idea to implementation and quality assurance.
## Project Start Steps
### 1. Begin with Requirements Analysis
Use the `requirements_analyzer` prompt:
...If you see prompt template content like the above, the connection is working.
Error Responses
If the configuration is incorrect, you may see errors like:
Unknown MCP server: psm: The server namedpsmwas not registered correctly. Check withclaude mcp list.Failed to get response from MCP server: ...: The MCP server URL may be wrong or the server is not running. Verify the URL provided by your administrator.401 Unauthorized/Bearer token required: TheAuthorizationheader is not set or the token is invalid. Re-register the server with the correct token (see Step 3).
Mention-Based Invocation
In addition to slash commands, you can mention the server with @<server-name> and make requests in natural language:
@psm Use the project_start prompt to explain how to begin a new projectIf this also works, your setup is complete.
Choose Your Workflow
Running project_start will guide you to the next steps.
Start from Discovery Phase (recommended for new products)
If you want to first clarify actors, value propositions, and user stories:
/mcp__psm__product_discoveryFlow: product_discovery → feature_design → screen_design_brief (optional) → requirements_analyzer
Start from Requirements Definition
If you already know what you want to build:

Congratulations! You're now ready to interact with the Prime Style MCP server through Claude Code.
