Common questions
Is Firmament safe?
It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

Agents get cheaper, better and faster + multiplayer.
Firmament is the shared context layer for your team's agents. They ask what is
true here before they act, and record what they learn on the way out.

Firmament MCP server
Your team's shared knowledge, available to every agent.
Firmament holds what is true about your company and how work actually gets done there: the decisions, the numbers, the gotchas, and the exact steps that work in your organisation. None of that is in any model's training data, so an agent without it guesses, or works from a document that went stale months ago.
This server exposes Firmament to any MCP client over a hosted HTTP endpoint. There is nothing to install and nothing to run locally.
What it does
Two tools.
`ask` looks up what your team already knows, before the agent acts or answers. It covers both kinds of knowledge: facts about your organisation (its products, customers, metrics, status, decisions) and how work gets done in it (conventions, prerequisites, the step that is not in the README).
`submit` records what the agent learned on the way out: a new fact, a decision and its reasoning, a number, what failed and why, or the full recipe for a multi-step process. That goes back to the shared knowledge base, so the next session and every teammate's agent starts from it.
The result is that knowledge accumulates as work happens, instead of being written up later by whoever has time.
Configuration
The server is remote and speaks streamable HTTP. Point your client at:
https://mcp.getfirmament.com/mcpAuthentication is OAuth 2.1 with dynamic client registration, so most clients need nothing beyond the URL. You sign in once in your browser when the client first connects, and it handles the rest.
VS Code
Add it from the Extensions panel by searching @mcp, or add the URL directly to your MCP configuration as an HTTP server.
Other clients
Any MCP client that supports remote HTTP servers works. Firmament also ships first-class packages for several agents, so you may prefer those:
| Agent | Install |
|---|---|
| Claude Code | claude plugin marketplace add spkenny455/firmament-plugin then claude plugin install firmament@firmament |
| Gemini CLI | gemini extensions install https://github.com/spkenny455/firmament-gemini-extension |
| Cursor, Codex, Copilot CLI | see firmament-plugin |
Using it
You do not need to prompt the tools by name. The packages above ship a standing instruction so the agent consults Firmament on its own. With a bare MCP connection, the tool descriptions carry the same guidance.
In practice it looks like this:
- Before a deploy, the agent asks how releases are actually done here and gets your runbook, including the manual step missing from the README.
- Asked about pricing, a discount or a refund, it checks your team's approved answer before replying to a customer.
- After a long debugging session, it records the root cause and the fix, so nobody loses a day to it again.
- After a multi-step migration, it submits the recipe with the exact commands, so the next person runs it in one pass.
Accounts
Firmament is a hosted product. Sign up at getfirmament.com. Knowledge is scoped to your workspace, and the server resolves every call to a workspace and user from the OAuth token, so one team's knowledge is never visible to another.
