The Namespace MCP server lets AI agents investigate builds and GitHub Actions jobs, analyze compute and CI usage, and manage Devboxes.

Connect your agent

Add the server to your agent, then log in.

Claude Code
Codex CLI
Cursor
VS Code
Amp
Gemini CLI

Add the server for all your projects:

Read and write

Read only

claude mcp add --transport http --scope user namespace https://mcp.namespace.so/mcp

claude mcp add --transport http --scope user namespace https://mcp.namespace.so/mcp/readonly

Log in by running /mcp in a Claude Code session, selecting namespace, and choosing Authenticate. You can also log in from the terminal:

claude mcp login namespace

To check the connection, run claude mcp list.

Add the server:

Read and write

Read only

codex mcp add namespace --url https://mcp.namespace.so/mcp

codex mcp add namespace --url https://mcp.namespace.so/mcp/readonly

Or add it to ~/.codex/config.toml:

~/.codex/config.toml

[mcp_servers.namespace]
url = "https://mcp.namespace.so/mcp"

If Codex doesn’t open the login when you add the server, log in with:

codex mcp login namespace

To check the connection, run codex mcp list.

Install the server with one click:

Access	Install
Read and write
Read only

After you add the server, Cursor opens Customize > MCPs. Select Authenticate on the Namespace tile to log in.

Install the server with one click:

Access	Install
Read and write
Read only

After you add the server, VS Code asks you to authenticate. Select Allow to log in.To check the connection, run MCP: List Servers from the Command Palette.

Add the server:

Read and write

Read only

amp mcp add namespace https://mcp.namespace.so/mcp

amp mcp add namespace https://mcp.namespace.so/mcp/readonly

Amp opens the login in your browser the next time you start it.To check the connection, run amp mcp list.

Add the server for all your projects:

Read and write

Read only

gemini mcp add --transport http --scope user namespace https://mcp.namespace.so/mcp

gemini mcp add --transport http --scope user namespace https://mcp.namespace.so/mcp/readonly

Gemini CLI opens the login in your browser when it first connects. To log in again, run /mcp auth namespace in a session.To check the connection, run gemini mcp list.

Choose access

Endpoint	Access	Use it to
`https://mcp.namespace.so/mcp`	Read and write	Let the agent do everything available with read-only access, plus create, start, stop, and delete Devboxes and run commands in them.
`https://mcp.namespace.so/mcp/readonly`	Read only	Let the agent investigate GitHub Actions jobs and builds, analyze compute resource usage, and check the Namespace service status without changing anything.

The first time your agent connects, it opens Namespace in your browser. Review the requested permissions, then authorize the workspace it can access.

Read-only access only limits the Namespace MCP server. An agent with shell access can still use nsc or devbox with your local credentials.

Common use cases

Use case	Example prompt
Investigate jobs	”Why did Namespace GitHub Actions job `<job-id>` fail?”
Analyze CI usage	”Which GitHub Actions jobs ran most often on Namespace this week?”
Right-size runners	”Which GitHub Actions jobs running on Namespace can move to smaller runners?”
Investigate builds	”Why did Namespace container image build `<build-ref>` fail?”
Instance observability	”Why did Namespace instance `<instance-id>` fail? Chart its resource usage.”
Devboxes	”Create a Namespace Devbox, make a Hello World HTML page, serve it, and expose it at a private `devbox.so` URL.”

Use MCP with local tools

For the most efficient workflows, install nsc, devbox, and the GitHub CLI alongside the Namespace MCP server. MCP connects the agent to your Namespace resources. When a task needs capabilities it doesn’t provide, it may guide the agent to the appropriate CLI.

Tool	Best for
Namespace MCP	Finding and connecting workspace resources, CI usage, and compute metrics.
`nsc`	Complete, live, or cross-instance logs and other Namespace CLI workflows.
`devbox`	Uploading local files and working directly with Devboxes.
GitHub CLI	Pull request and commit context, and complete or live GitHub Actions logs.

Manage access

Each connection is authorized for one workspace. To use another workspace, add the server under a different name and authorize it separately. Sessions renew automatically.To review or revoke access, open Applications in the Namespace dashboard. Revoked agents must log in again.

Troubleshooting

Problem	Resolution
The agent needs authentication	Start the login from your agent using the instructions under Connect your agent.
Write tools are missing	Connect to `https://mcp.namespace.so/mcp` instead of the read-only endpoint, then log in again.
Authentication failed	The approval may have been revoked. Log in again from your agent.
Permission denied	Check that you authorized the correct workspace and that your Namespace role can access the resource.
