The context your code doesn't have.
Connect Cursor to your company brain and ask what the client signed off, why a feature changed or what's on your plate, without leaving the editor. One entry in your MCP settings, then sign in.

Launch is December 3. One blocker: the final pricing page copy, which is late.
Ines, their head of product. Anything touching pricing also goes to their CFO.
Same Cursor. Different answers.
Each developer's Cursor answers with that person's access. Ask as Rosa, who leads delivery, then as Sam.
$12,400 of $40,000, on track for the December 3 launch.
I can't see budgets with your access. What I can see: launch on December 3, four tasks open.

Cursor and Brainstack, at a glance.
- Where it works
- The Cursor editor, from the Agent chat.
- Setup
- One entry in
~/.cursor/mcp.json(all projects) or.cursor/mcp.json(one repository). Team admins can share it with everyone. - Sign-in
- OAuth with each person's Brainstack account. No API keys in config files.
- What Cursor can reach
- Knowledge, tasks and projects (beta), only in the spaces that person's role can open.
- Your code
- Brainstack answers what Cursor asks. It doesn't read your repository.
- Where your data lives
- The brain stays on your own server in the US or Europe. Cursor and its model providers process what they receive under your Cursor plan.
Questions, answered.
Does Cursor work with Brainstack?
Yes. Cursor supports remote MCP servers with OAuth sign-in. Add Brainstack to mcp.json, sign in, and the Agent chat can answer from your company's knowledge, tasks and projects.
Global or project config?
Use ~/.cursor/mcp.json to have Brainstack in every project. Use .cursor/mcp.json inside a repository to share the entry with the team; each person still signs in with their own account.
Is there an API key in the config?
No. The config only holds your brain's address. Access comes from each person signing in, so the file is safe to commit.
Does Brainstack read our code?
No. Brainstack answers the questions Cursor sends it. Your repository stays where it is.
Will Cursor see everything in our brain?
No. Each developer signs in as themselves and sees only the spaces their role can open.
What does it cost?
Team AI access comes with every Brainstack plan, from $99 a month. Your team keeps its Cursor plan.
Cursor support checked on October 26, 2026.
