Common questions

Is Assay Truth Graph MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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 hands that context to Claude, ChatGPT, Cursor, Claude Code, Codex, and other MCP clients without copying company facts into each agent.

Two tools are the front door, and most work needs nothing else:

  • assay (read-only): send the user's request and what you know (an account, people's titles, the channel). You get what to lead with and whether a named person approved it, the approved proof to cite, objections, claims to avoid, what changed since last time, and what is missing with a link to fix it. It also checks a draft before it ships, and answers questions about rivals.
  • assay_act (writes, always two-step): record what happened (an objection, a deal outcome, a message that landed), keep a thread for an account or deal, confirm who a situation is about, or have Assay draft something. Every action previews first and runs only with the plan token after the person agrees.

Behind them, the server has full parity with the Assay app: Truth Graph search and governed mutation, content validation, collateral, AI search and GEO, readiness simulation, pre-call briefs, and review and promotion. Call tools/list on the live endpoint for the current surface.

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.

Replit one-click install:

Codex repo marketplace:

codex plugin marketplace add Assay-Org/assay-truth-graph-mcp

Then install the Assay Truth Graph plugin from Codex Plugins.

What Agents Can Do

  • Get a brief for a meeting, deal, launch or board conversation: what to lead with for this audience, who approved it, and the proof to cite.
  • Prepare for several accounts in one call.
  • Get verified GTM context for customer-facing drafts.
  • Search the Truth Graph with provenance and caller-aware context shaping.
  • Validate draft content against approved facts and guardrails before it ships.
  • Create or update Truth Graph records through dry-run and human-approved plan-token workflows.
  • Generate grounded collateral drafts in quarantine, with preview and export gates, and re-render them when the underlying story changes.
  • Run the AI search and GEO workspace: briefs, artifacts, evidence, goals, hosted sites, and approval-gated publishing.
  • Run readiness simulations and build pre-call briefs.
  • Review, approve, and promote through the same gates the app uses.

Two entitlement lanes are enforced server-side. mcp_access covers read and verification tools on Free and above. mcp_control_access covers write and run tools on Scale and above. Writes are dry-run by default and mint a single-use, expiring plan token that must be confirmed. Pricing, policy, proof, and identity kinds are refused for autonomous mutation, and unmapped kinds fail closed.
