Assay Truth Graph MCP

Assay Truth Graph MCP is a remote MCP server for GTM teams that need AI agents to work from governed, cited company truth.

Assay turns positioning, proof points, brand voice, personas, collateral context, and validation rules into a governed Truth Graph. The remote MCP server lets Claude, ChatGPT, Cursor, Claude Code, Codex, and other MCP clients use that context without copying company facts into each agent.

Connect

Use the remote streamable HTTP endpoint:

https://app.assay.wiki/api/mcp/v2/mcp

Claude Code:

claude mcp add --transport http assay-truth-graph https://app.assay.wiki/api/mcp/v2/mcp

Generic MCP config:

{
  "mcpServers": {
    "assay-truth-graph": {
      "type": "http",
      "url": "https://app.assay.wiki/api/mcp/v2/mcp"
    }
  }
}

OAuth opens in the browser on first use for interactive clients. Headless agents can authenticate with an org API key from Assay Settings.
