MCP Server Managers: Compare Setup, Updates, and Access Controls
Managing MCP server configurations across a team means tracking which servers are connected, who approved each connection, and what happens when a server updates or moves. This guide compares the main approaches and explains what a team needs beyond a single developer's config file.

An MCP server manager is anything that controls which servers your AI clients connect to, how they start, and who can change that list. For a single developer, a config file in a text editor is enough. For a team, managing those connections requires tracking approvals, ownership, and what each server can access.
Most teams discover the gap when someone adds a server that a colleague does not know about, or when a server's endpoint changes and three clients break at once. Tools like fenbs record which connections the team has approved and who is responsible for each one, so that gap has an answer.
What server management involves
Managing MCP servers is three distinct jobs. Configuration is the initial setup: adding the server to each client's config file or GUI with the right command, URL, or credentials. Updates are the ongoing work: when a server moves, changes its authentication, or adds new tools, all affected clients need to change.
Access control is the team question: who decided this server should be connected, what may it do, and who reviews a new connection before it goes into shared use? For a personal developer setup, access control is implicit. For a team that uses AI assistants in client work, it matters explicitly.
Config-file approaches
Claude Desktop stores MCP server configuration in a JSON file on your machine. Claude Code reads a similar file. Cursor has its own MCP settings panel. Each client has its own format, its own location, and its own way of starting and stopping servers.
A config file is the right starting point for a single developer. It is readable, version-controllable, and easy to copy to another machine. The limit is that it is per-person: updating a config means editing a file on every developer's machine separately.
Some teams share a base config file through a version-controlled repository. That helps with standardization but does not solve the problem of credentials, which must stay out of version control. Each developer still manages their own copy of the sensitive parts.
GUI-based server management
Some AI clients provide a graphical interface for adding and removing MCP servers. Claude Desktop's settings panel shows connected servers and lets you enable or disable them. Cursor's MCP tab lets you add servers without editing JSON directly.
GUI management is more accessible for non-developer team members. The trade-off is that changes made through a GUI are harder to audit — there is no commit history, no change record, and no way for someone else to check what was added and when.
For teams that mix technical and non-technical members, a GUI lowers the setup barrier. Pair it with a written record of which servers are approved and why, so the team has an answer when someone asks.
Comparison of management approaches
| Approach | Good for | Access control | Update management |
|---|---|---|---|
| Per-developer config file | Individual developers; self-managed tools | Implicit: developer owns their config | Manual: each developer updates their own file |
| Shared base config (version-controlled) | Small teams with common tool sets | Checked by code review; credentials excluded | One update propagates to all developers on next pull |
| Client GUI (Claude Desktop, Cursor) | Non-technical team members; quick setup | No audit trail unless paired with a written record | Manual per-person; no central update mechanism |
| Shared registry or decision record (e.g. fenbs) | Teams that need approved connections and audit history | Human decision recorded with owner and date | One update; all team members read the current record |
| fenbs | Teams keeping decisions, rules and approved MCP connections together | Role-based; decisions record who approved each connection | Update the decision; all connected AIs read the current version |
What teams actually need
For most small teams, the practical need is a list of approved MCP servers with the following for each: the server name, the endpoint or command, who approved it, what it may access, and when it was last reviewed.
That list does not need specialized software — it can live in a project's Decisions and rules record. What matters is that the list exists in a shared place, is updated when connections change, and is consulted before adding a new server.
For larger teams or teams in regulated industries, the need is more formal: approval workflows, change history, and per-server permission records. Those requirements push toward proper governance tooling rather than a shared config file.
Record which MCP connections your team has approved
Add each approved MCP server as a Decisions and rules entry in fenbs: the server name, what it may access, who approved it, and the date. When a new server is proposed, open it as a decision for the team rather than adding it unilaterally. Every AI connected to fenbs reads those decisions, so the current list of approved connections is always in context.

Managing server updates
Remote servers can change their endpoints, authentication methods, or tool names without warning. When that happens, every client that was connected breaks until its configuration is updated.
The way to stay ahead of this is to record the endpoint URL and the version you tested against, then review it when a server announces a change. For servers your team maintains, add a task to the project when a change is planned so that updating client configurations is part of the release process, not an afterthought.
For third-party servers, follow the server's release notes or changelog. The mcp server directory is one place to track available servers and check for status updates.
How to do this with fenbs
- Create a free account and set up a project for your team's AI tooling decisions.
- Add each MCP server your team uses as a Decisions and rules entry: the server name, its endpoint, what it may access, the person who approved it, and the date.
- When a new server is proposed, add it as an open decision and let the team discuss before connecting it across all clients.
- When a server changes its endpoint or authentication, update the decision and note what changed. The old version stays in history.
- Connect your AI apps to fenbs over MCP from Integrations so every AI session starts with the current approved server list in context.
