RightNow AI is a YC-backed GPU research lab and software company. Its flagship product is RightNow Agent, the fastest coding agent harness in the world. It also builds the RightNow editor and Forge.

What is RightNow Agent?

RightNow Agent is the fastest coding agent harness in the world, a Rust terminal CLI built for one thing: speed. On the measured Windows path, a warm daemon opens a session in 105 to 115 ms.

Which NVIDIA GPUs does the RightNow editor support?

The RightNow editor supports all NVIDIA GPUs with CUDA Toolkit 11.0-12.5, including GeForce RTX 40/30/20 series, GTX 16/10 series, Quadro RTX, Tesla, A100, and H100.

How much does RightNow AI cost?

RightNow AI is free to use with unlimited profiling and benchmarking. RightNow Pro costs $20 per month and adds GPU emulator access (50+ GPUs), multi-GPU comparison, and 1,000 AI credits per month.

What CUDA development workflow does the RightNow editor support?

The RightNow editor supports CUDA development workflows that combine editing, profiling, emulation, remote GPU execution, and benchmarked performance analysis.

Can I use the RightNow editor on macOS?

Yes, the RightNow editor is available on macOS (Apple Silicon and Intel). Mac users can use remote GPUs for free or our built-in GPU emulator for CUDA profiling.

MCP Servers

RightNow Agent uses Model Context Protocol servers to add external tools. Enabled server tools can be discovered and called alongside RightNow's built-in tools.

Transports

Transport	Configuration	Use
stdio	command, args, env	Spawn a local MCP process and communicate over stdin and stdout.
HTTP / SSE	url, optional headers	Connect directly to a remote MCP endpoint.
streamable HTTP	url, optional session ID header	Use an HTTP MCP endpoint that maintains a session identifier.

toml

[mcp_servers.filesystem]
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "C:/work"]
enabled = true

[mcp_servers.remote-api]
url = "https://mcp.example.com/api"
headers = { Authorization = "Bearer ${MCP_TOKEN}" }

[mcp_servers.streamable]
url = "https://mcp.example.com/api/mcp"
headers = { "x-mcp-session-id" = "{{session_id}}" }

User and project scope

Location	Scope and priority
~/.rightnow/config.toml	User scope for all projects. Lowest native priority.
<repo>/.rightnow/config.toml	Shared repository definition.
<cwd>/.rightnow/config.toml	Deepest project definition. Highest native priority.

A project server replaces a same-named global server rather than merging fields. Existing .grok/config.toml is read only when the corresponding .rightnow/config.toml is absent.

Command-line management

bash

rightnow-pager.exe mcp list
rightnow-pager.exe mcp list --json
rightnow-pager.exe mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem C:/work
rightnow-pager.exe mcp add --transport http api https://mcp.example.com/mcp
rightnow-pager.exe mcp add --transport sse linear https://mcp.linear.app/sse
rightnow-pager.exe mcp enable filesystem
rightnow-pager.exe mcp disable filesystem
rightnow-pager.exe mcp doctor filesystem
rightnow-pager.exe mcp remove filesystem

The transport defaults to stdio. rightnow-pager.exe mcp add writes user scope by default; add --scope project to write the current directory's project config.

Runtime controls and discovery

Run /mcps to inspect servers, toggle them, view tools, refresh configuration, and authenticate supported servers.
Tool names use server__tool, such as github__create_issue.
search_tool finds tools across enabled servers by name or description.
use_tool calls a discovered tool by its fully qualified name.

Trust server definitions

MCP servers retain their own command, network, and credential behavior. Review every command, argument, environment variable, URL, and header before launch. Project servers are gated by folder trust.

Importing existing MCP configuration

The Windows migration tool imports Claude Code or Codex MCP definitions only when you opt in with -WithMcp. It does not modify the source configuration.
