Connect Claude Desktop to Fygment

Add Fygment as a Claude custom connector with the hosted MCP URL and OAuth, without copying a workspace key into Claude Desktop.

Audience
Claude Desktop and Claude web users connecting their workspace through a custom connector.
Updated
2026-10-25

Claude connects directly to Fygment’s hosted endpoint. Add a custom connector with the bare URL, sign in with Claude’s published identity, then approve the workspace in Fygment.

What this connection does

MCP (Model Context Protocol) is a standard way to let an AI client use Fygment workspace tools.

Claude uses Fygment’s hosted connection and OAuth. Do not add an API key, workspace slug, query string, or custom header to the URL.

Connect on a Pro or Max plan

These steps follow Anthropic’s guide to custom connectors. Menu names can change.

  1. 1

    Open the connector settings

    In Claude, open Customize, then Connectors. Choose +, then Add custom connector.

  2. 2

    Enter the name and URL

    Set Name to Fygment and the server URL to https://fygment.dev/api/mcp. Choose Continue.

  3. 3

    Review the sign-in settings

    Claude shows the authentication settings it found for Fygment. Review them and choose Continue.

  4. 4

    Choose how to sign in

    For Authentication, choose Sign in now. For OAuth client, choose Use Claude’s published identity (Recommended). Add no request headers. Choose Add.

  5. 5

    Sign in and approve

    Sign in to Fygment and approve the workspace connection.

Connect on a Team or Enterprise plan

  1. 1

    An Owner adds Fygment once

    An Owner opens Organization settings, then Connectors. They choose Add, then Custom, then Web, and enter Name Fygment and the URL https://fygment.dev/api/mcp.

  2. 2

    Each member connects

    Each member opens Customize, then Connectors, finds Fygment, and chooses Connect. Then they sign in to Fygment and approve the workspace.

Use it in a chat

  1. 1

    Turn Fygment on if needed

    If Claude does not use Fygment, open + in the chat, then Connectors, and turn Fygment on.

  2. 2

    Verify the connection

    Ask Claude to search Fygment for a known workflow. If it fails, remove the connector and add it again with the exact URL above.

Plan limits

Free plans allow one custom connector

On the Claude Free plan you can add one custom connector. Fygment discovers OAuth details through the hosted endpoint, so you never need a static client secret.

Related docs

  • Set up Fygment MCP

    MCP setup gives AI clients access to workspace-scoped Fygment tools. Hosted clients use OAuth; local clients use guided setup and a local authenticated proxy where needed.

  • MCP tools reference

    The Fygment MCP server offers 20 tools. Most need a permission (scope) that you approve when you connect: fygment:read, fygment:write or fygment:install. Two account tools need none.

  • Connect ChatGPT to Fygment

    ChatGPT connects to Fygment’s hosted endpoint. Add a custom MCP server in Plugins, keep OAuth, create it as a plugin, and approve only the workspace you intend to use.

  • Connect another MCP client to Fygment

    Use the bare hosted endpoint, select OAuth or protected-resource discovery, and confirm that the client can complete a workspace-scoped Fygment approval.

  • Troubleshooting

    Start with safe, non-sensitive checks. Fygment support reports should capture bounded diagnostics, not package bodies, secrets, raw prompts, or local paths.
