Your team's shared, verified knowledge for AI agents: ask what's true, record what you learn.

Overview

AI-generated overview

Hosted MCP server that gives an assistant your team's shared knowledge base: it looks up verified facts and runbooks, and records new learnings.

What you can do
  • Look up what the team already knows before acting: organisational facts, products, customers, metrics, status and decisions, plus conventions and prerequisites for how work gets done.
  • Record what the agent learned: a new fact, a decision with its reasoning, a number, a failure and its cause, or the full recipe for a multi-step process.
  • Feed those submissions back into the shared knowledge base so later sessions and teammates' agents start from them.
When to use it
Useful when agents need company-specific context that is not in any model's training data, such as release runbooks, approved answers on pricing or refunds, or hard-won debugging and migration steps, and when you want what agents learn to accumulate for the whole team.
Requirements
A remote streamable HTTP endpoint; nothing to install or run locally. A Firmament account and workspace, with OAuth 2.1 sign-in in the browser on first connection (dynamic client registration). Any MCP client that supports remote HTTP servers.
Before you install
Knowledge is stored in a hosted third-party product and scoped to your workspace via the OAuth token. The submit tool writes agent-generated content into the shared knowledge base, so incorrect or sensitive details can spread to every teammate's agent; review what gets recorded.

Installation

In SourceWeft

  1. Open Firmament in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.getfirmament%2Ffirmament/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

[Firmament, the agent-first context layer for your teams]

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/mcp

Authentication 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:

AgentInstall
Claude Codeclaude plugin marketplace add spkenny455/firmament-plugin then claude plugin install firmament@firmament
Gemini CLIgemini extensions install https://github.com/spkenny455/firmament-gemini-extension
Cursor, Codex, Copilot CLIsee 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.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
