Octave documentation

What it does

A GTM context engine that stores a company's ICP, personas, positioning, competitors, proof points, and objections as one structured model, then serves that model to sequences, scripts, and AI agents at runtime through an API and an MCP server so every tool uses the same current messaging.

Access and connection

MCP support: official

Access requirements: paid. A Base plan exists at no cost but is capped (2 workspaces, 1 offering, limited elements, playbooks, and generation) and does not list API or MCP access. MCP, API, CLI/SDK, and the Claude Code plugin are listed under Octave Ultra, which starts at $1,500/month billed annually. Signup is self-serve with a free trial, so a solo operator can reach the product without a sales call, but not the MCP or API tier.

Authentication: Browser OAuth. Per the vendor's Claude Code setup doc you add the server with "claude mcp add octave-myWorkspace --transport http https://mcp.octavehq.com/mcp?ctx=YOUR_CONTEXT" then run /mcp and "Select the Octave server and authenticate via your browser." No API key header path is documented for the MCP. The separate REST API v2 uses a different scheme, an API key passed in an "Api key" header, issued from app.octavehq.com.
