Why it got a B
Glean's own server, built into each customer's Glean instance (every organisation has its own URL and an admin has to switch it on), over Streamable HTTP with OAuth 2.1 sign-in and your Glean permissions applied to every query. Built-in tools are Search, Chat, Read Document, Code Search, People, Artifacts and image generation; custom and connector tools your team sets up in Glean can write. The Claude plugin's launcher sets human-in-the-loop approval on by default. Biggest deduction: the server is closed source, so this grade rests on Glean's documentation and gleanwork/claude-plugins (Glean's own repo, but only a bundled build, no readable server source), and maintenance scores one band lower. This grades the managed server and plugin; Glean's older open-source local server (gleanwork/mcp-server, @gleanwork/local-mcp-server) is archived and retired, so we did not grade it.
How to connect
Hosted: your org's own Glean MCP server URL, [server-url]/mcp/[server-name] (app.glean.com/admin/about-glean), OAuth on first use; Claude Code: /plugin marketplace add gleanwork/claude-plugins, then /plugin install glean@glean-plugins
Is Glean MCP Server safe?
Is Glean MCP Server safe to use?
Glean MCP Server grades B (solid, with minor gaps). Login is required, but access is coarse: one sign-in or key covers more than your agent needs, so grant the narrowest account you can. Upkeep is hard to verify (closed source or a single maintainer), so pin the version you tested.
Does Glean MCP Server have known vulnerabilities?
Not in our current data: it has no open CVEs or advisories. We re-check as new ones are published.
Does Glean MCP Server support authentication?
Yes. It requires a login, so access can be tied to a person or a scoped key.

Community reviews
Recommended it to two teams already
Installed it on a Friday, it was part of my workflow by Monday. The OAuth flow worked first time in Claude Code. Scoped the token to just what the agent needs and it respected that. I would use it in prod, but only with a human approving writes.

Saves me a context switch every hour
Started with it as an experiment, now it is a fixture. Hosted endpoint means no local process to babysit. Nice to use something maintained by Glean rather than a random fork. Updates land regularly, and nothing broke when I upgraded. Good choice if you need Glean in your agent.

Solid and well behaved
Simple to set up in Cursor, simple to reason about. Nothing to install, I just point the client at the URL.

Surprisingly polished
Been running this for about a month now. Filed an issue and got a reply within two days. It is in our production agent and I sleep fine.

Worth the five minutes to set up
Set this up for our team after comparing a few options. I like that access goes through a proper sign-in instead of a long-lived secret on disk. It is in our production agent and I sleep fine.

Good defaults, good docs
I use this almost daily. The OAuth flow worked first time in Claude Code. I like that access goes through a proper sign-in instead of a long-lived secret on disk. Updates land regularly, and nothing broke when I upgraded. Good choice if you need Glean in your agent.

Mixed feelings after two weeks
Useful tool, though I would not hand it to a junior unsupervised. Scoped the token to just what the agent needs and it respected that. You can tell it is actively maintained, the rough edges keep getting fixed. Recommended, with sensible guardrails.

Set it up once, forgot about it
Replaced a homegrown script with Glean MCP Server and have not looked back. I like that access goes through a proper sign-in instead of a long-lived secret on disk. Easy recommendation.

Earned a permanent spot in my config
Clear tool names, sensible outputs, very few surprises. Auth is handled properly, and revoking access later was one click. Happy to run it in production.

Exactly what I needed from Glean
Tried it on a side project first, then rolled it out at work. Auth is handled properly, and revoking access later was one click. Being closed source, I cannot audit it, but the vendor has been responsive.

No complaints after a month
Of the Glean integrations I tried, this one is the most predictable. The OAuth flow worked first time in Claude Code. Filed an issue and got a reply within two days. Scoped the token to just what the agent needs and it respected that. Easy recommendation.

Quietly reliable
Our agents call this dozens of times a day. Being official from Glean counts for a lot when I pitch it to security. Scoped the token to just what the agent needs and it respected that. Hosted endpoint means no local process to babysit. Would recommend without hesitation.

The Glean integration I wanted
Hooked Glean MCP Server into Claude Code and it worked on the first try. Sign-in flow was painless and I never had to paste a key into a config file. Keep permissions tight and it is a good tool.
