Fusion MCP Setup Guide

When to use

Use when a user asks:

• what Fusion MCP is
• what it can do
• how to install/configure it
• how to verify it is working
• how to troubleshoot a failing Fusion MCP setup

Typical triggers:

• "what is fusion mcp"
• "help me set up fusion mcp"
• "how do I use fusion mcp with copilot"

When not to use

• Implementing product features unrelated to MCP setup
• Making destructive environment changes without user confirmation
• Assuming private repository details not visible
• Answering source-backed questions about Fusion Framework APIs, EDS components, or the skill catalog — once MCP is running, use fusion-research for that

Required inputs

Collect before proposing setup steps:

• user environment (OS, editor/runtime)
• target client where MCP will run (VS Code is primary target)
• whether user's Equinor Entra account is available

If details are missing, ask concise follow-up questions first.

Instructions

1. Explain what this MCP server provides:
   • Fusion-oriented MCP capabilities for retrieval and workflow support
   • hosted as a managed service — no local infrastructure required for most developers
   • retrieval tools: search, search_framework, search_docs, search_eds, search_indexes, search_backend_code
   • tool surface may evolve over time
2. Guide user to set up the hosted production server — the only recommended path:
   • no Docker, no API keys, no local clone needed
   • VS Code authenticates via Microsoft Entra (Equinor account)
   • use the one-click install link for prod (see references/vscode-mcp-config.md)
   • or manual config with "type": "http" and server URL (see references/vscode-mcp-config.md)
   • don't suggest local Docker, GHCR, or self-hosted alternatives unless user has explicit operational need
3. Describe the authentication flow:
   • on first tool invocation VS Code prompts sign in with Equinor Entra account
   • tokens managed automatically; silent renewal when possible, interactive prompt when needed
   • access controlled by existing Fusion role assignments
4. Provide a lightweight MCP smell test:
   • run initialize and confirm successful response
   • run tools/list and confirm at least one tool returned
   • run one non-destructive tools/call against an available tool
   • pass criteria: call response is non-empty (content or structuredContent contains data)
   • note: don't hard-code a fixed tool list; tool inventory can change between versions
5. Troubleshoot in documented order:
   • Entra sign-in prompt not appearing → verify oauth.clientId in config and that VS Code is signed in with an Equinor account
   • 401 Unauthorized → re-authenticate via VS Code account settings; ensure Equinor Entra account is active
   • tools/list returns empty or tool call fails → verify MCP server entry is selected/enabled in VS Code and retry after reloading
   • partial tool behavior → check VS Code Output > Copilot for error details and restart the MCP server
6. When MCP setup fails or user asks to file a bug, produce a bug report draft from assets/bug-report-template.md.
   • default target repository: equinor/fusion-mcp
   • include concrete repro steps, expected vs actual behavior, and troubleshooting already attempted
   • include non-sensitive environment details (OS, VS Code version, MCP server URL, Entra account type)
   • never include secrets, tokens, or raw credential values
7. For uncertainty or repo-private constraints, state assumptions explicitly and link to authoritative docs instead of guessing.

Expected output

Return:

• short explanation of Fusion MCP and when to use it
• hosted prod setup steps tailored to the user environment
• validation checklist: run initialize (expect success response), run tools/list (expect at least one tool), run one tools/call (expect non-empty content or structuredContent)
• troubleshooting steps mapped to observed error symptoms
• bug report draft (when setup fails/misbehaves or user requests) using assets/bug-report-template.md with default target equinor/fusion-mcp
• script snippets when user asks for copy/paste automation aids
• assumptions and missing information called out explicitly
• links to the exact upstream docs used

Safety & constraints

Never:

• request or expose secrets, tokens, or credentials
• invent setup commands that are not supported by project documentation
• claim setup succeeded without validation output
• run destructive commands without explicit user confirmation

Always:

• prefer official repository documentation as source of truth
• guide users to the hosted production server; do not suggest local Docker or self-hosted alternatives
• provide least-privilege, minimal-change setup guidance first
• separate confirmed facts from assumptions
