Supported Copilot surfaces

  • Copilot Studio: Microsoft’s agent-building tool. The Affinity tool is added to an agent by its author and is available to every user of the agent.
  • Copilot CLI: the GitHub Copilot command-line tool, configured per developer.
  • Copilot in VS Code: configured per developer (or committed at the workspace level).
The following Copilot surfaces do not currently support remote MCP servers:
  • Copilot chat on github.com and copilot.com
  • The GitHub mobile apps
Why are those surfaces unsupported? Remote MCP currently requires HTTP custom-header support, which Copilot chat on github.com / copilot.com and the GitHub mobile apps don’t yet expose. Microsoft / GitHub may add this later; check their changelog.
If you’re using one of those surfaces, MCP isn’t available there yet. Use one of the three supported surfaces above.

​
Prerequisites

Affinity
  • Plan: Scale, Advanced, or Enterprise (required for API and MCP access).
  • API key: Generate one before starting. See Authentication. We do not currently support OAuth with Copilot.
  • Admin setup: None required by default. If an Affinity admin has disabled Copilot under Settings → Affinity MCP, ask them to re-enable it.
Copilot
  • Plan:
    • Copilot Studio: A Microsoft Copilot Studio license is required. MCP tools authored in Studio inherit the publisher’s licensing for end users.
    • Copilot CLI / VS Code: An active GitHub Copilot subscription (Individual, Business, or Enterprise).
  • Admin setup:
    • Copilot Studio: Only the agent author configures the tool. Once added, every user of the agent uses Affinity through that single tool definition.
    • Copilot CLI / VS Code: Each developer configures their own client. No org admin step is required, though a Business / Enterprise admin can centrally manage Copilot policies for the org.
Copilot connects to the Affinity hosted MCP server (https://mcp.affinity.co/mcp) using API key authentication. We do not currently support OAuth across Copilot surfaces.
Get an Affinity API key in 3 steps: In Affinity, go to Settings → Manage Apps → API Keys → Create new key. Copy the key immediately — you won’t see it again. Name it something memorable (e.g., “Copilot MCP”).

​
Setup

Set up in Copilot Studio is performed by the agent author. Once added, the tool is available to every user of the agent.

​
Agent author: add the MCP tool

  1. In Copilot Studio, open your agent and go to the Tools page.
  2. Select Add a tool → New tool → Model Context Protocol. The MCP onboarding wizard appears.
  3. Fill in the server details. Copilot Studio’s agent orchestrator uses the description to decide when to route requests to Affinity, so be specific about what the server provides:
    • Server name: Affinity
    • Server description: Use this server to search, read, create, and update records in the user’s Affinity CRM, including companies, people, opportunities, lists, fields, notes, meetings, meeting transcripts, and reminders.
    • Server URL: https://mcp.affinity.co/mcp
  4. For Authentication, select API key and configure:
    • Type: Header
    • Header name: Authorization
  5. Select Create, then on the Add tool dialog select Create a new connection.
  6. When prompted for the API key value, enter the full bearer token, including the Bearer prefix: 
    Bearer your_api_key_here
  7. Select Add to agent to finish.

​
Test your connection

Once configured, try one of these in your Copilot chat:
  • Find 3 companies I emailed in the last 30 days.
  • Show me my upcoming meetings.
  • Summarize recent activity on Acme Corp.
If you get Affinity data, you’re set. If not, see Troubleshooting.
