README

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.

The server has full parity with the Assay app. What the team does in the product, your agents can do here: 48 registered tools spanning 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:

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

Claude Code:

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

Generic MCP config:

json
{  "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:

[Install in Replit]

Codex repo marketplace:

bash
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 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.
