Why it got a B
Clay's own hosted server for its sales data and enrichment platform (clay.com), over HTTPS with OAuth sign-in, so there's no API key to store. Each token is tied to one user and one workspace, and Clay keeps only a hash of it. Tools find and enrich people and companies, add data points, check credits and run Functions an admin has turned on. Every enrichment spends the workspace's credits at the normal rate, so ask an admin for a per-user credit limit. Results are scraped and third-party data, so treat them as untrusted input. No advisories on record. Biggest deduction: OAuth offers one all-or-nothing scope, so a connection can do whatever your workspace role allows (a Viewer can still trigger runs), and admins can't revoke a single connection, only remove the user or set their credit limit to 0. The server is also closed source, so maintenance is scored one band lower. This is not the Clay personal CRM, which is now called Mesh.
How to connect
Hosted: https://api.clay.com/v3/mcp (OAuth sign-in, Clay workspace required). In Claude: add the Clay connector at claude.com/connectors/clayIs Clay MCP Server safe?
Is Clay MCP Server safe to use?
Clay 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 Clay 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 Clay MCP Server support authentication?
Yes. It requires a login, so access can be tied to a person or a scoped key.

Solid and well behaved
Replaced a homegrown script with Clay MCP Server and have not looked back. You can tell it is actively maintained, the rough edges keep getting fixed. Token setup is the fiddliest part, after that it is smooth. Sign-in flow was painless and I never had to paste a key into a config file.

Does the job, docs could be better
I like it, with reservations. Scoped the token to just what the agent needs and it respected that.

Exactly what I needed from Clay
Simple to set up in Cursor, simple to reason about. The OAuth flow worked first time in Claude Code. Sign-in flow was painless and I never had to paste a key into a config file.

Quietly reliable
Set this up for our team after comparing a few options. Releases come often and the changelog is clear. Scoped the token to just what the agent needs and it respected that. Nice to use something maintained by Clay rather than a random fork.

Easy win for our agent setup
Tried it on a side project first, then rolled it out at work. Sign-in flow was painless and I never had to paste a key into a config file.

Surprisingly polished
Hooked Clay MCP Server into Claude Code and it worked on the first try. Hosted endpoint means no local process to babysit. Filed an issue and got a reply within two days. I like that access goes through a proper sign-in instead of a long-lived secret on disk. Good choice if you need Clay in your agent.

Set it up once, forgot about it
Installed it on a Friday, it was part of my workflow by Monday. Gave it its own API key so I can revoke it without breaking anything else. Auth is handled properly, and revoking access later was one click. Fine in production if you sandbox it.

No complaints after a month
Started with it as an experiment, now it is a fixture. You can tell it is actively maintained, the rough edges keep getting fixed. Happy to run it in production.

Fine once configured properly
Some tools are great, a couple feel half finished. Nothing to install, I just point the client at the URL. Auth is handled properly, and revoking access later was one click. Gave it its own API key so I can revoke it without breaking anything else. Worth it, just do not skip the hardening steps.

Solid core, fiddly setup
Useful tool, though I would not hand it to a junior unsupervised. Auth is handled properly, and revoking access later was one click. The API key sits in the config file, so I made a dedicated key with minimal permissions. Not something I would put in production yet.

Good, but read the permissions first
Good for experimenting, still deciding about production. Sign-in flow was painless and I never had to paste a key into a config file. I would use it in prod, but only with a human approving writes.

Handy for dev, careful in prod
Took longer to configure than I expected. Releases come often and the changelog is clear. Scoped the token to just what the agent needs and it respected that. Recommended, with sensible guardrails.

Capable but needs guardrails
It does the job, but it took some tweaking. I like that access goes through a proper sign-in instead of a long-lived secret on disk. The API key sits in the config file, so I made a dedicated key with minimal permissions. Hosted endpoint means no local process to babysit.

Recommended it to two teams already
Clear tool names, sensible outputs, very few surprises. Auth is handled properly, and revoking access later was one click. The scope options are worth reading carefully, the defaults are broader than I wanted. Would recommend without hesitation.

Too many sharp edges
I wanted to like this one. Nothing to install, I just point the client at the URL. I will check back in a few releases.

Clean integration, sensible permissions
Of the Clay integrations I tried, this one is the most predictable. Updates land regularly, and nothing broke when I upgraded. Easy recommendation.
