Voyant.io

aid: voyant
name: Voyant.io
description: Voyant.io is a brand-context platform that turns a company's positioning, messaging, personas, products, pricing,
  and competitive intelligence into structured "context streams" that any AI tool or agent can read at generation time, so
  AI-produced copy stays on-message instead of drifting or hallucinating claims. The product is delivered as a large FastAPI-based
  REST API (783 operations across 79 tags covering context streams, RAG search, messaging frameworks, target graph, telemetry,
  social signal harvesting, competitive intelligence, and content generation), a hosted MCP server exposing 15 tools to agent
  clients, and a set of published agent-governance files (`/.well-known/llms.txt`, `/.well-known/context.txt`) that declare
  training permissions and inference-control rules for the domain itself. Marketed to B2B GTM teams scaling from $5M to $100M
  ARR. Pre-seed, founded by Andrew M. Brown; the API runs under the internal name "VoiceForge".

    personas, products, use cases, industries, testimonials), target graph and CRM context, telemetry and attribution, social
    signal harvesting (GitHub, Reddit, HackerNews, LinkedIn, YouTube, G2, Discord, government sources), competitive intelligence
    and battlecards, GEO/AEO intelligence, content and video generation, and generation of agent-facing artifacts (llms.txt,
    context.txt, trust.txt, ontology.jsonld) for the customer's own domain. Bearer-token authenticated.

  description: Hosted Model Context Protocol server (`voyant-mcp` 1.1.0) exposing 15 tools that let an agent client pull the
    organization's brand context, persona/funnel-modulated context, positioning, messaging, personas, products, use cases,
    industries, testimonials, competitive intelligence, market signals, and RAG search results, plus a content-generation
    tool. Tool list and input schemas are readable anonymously at `/mcp/tools`; calling a tool requires a `vio_*` API key
    or a Clerk token. SSE and JSON-RPC message transports.

  description: 'Second OpenAPI published by Voyant.io, discovered 2026-08-13 at https://www.voyant.io/openapi-gypsum.json
    (HTTP 200, application/json, 36,964 bytes). A clean 26-operation, 7-tag cut of the brand-context surface — messaging,
    positioning, personas, products, use cases, industries and testimonials context reads, plus ICP CRUD, campaign management
    and a brand-aware AI chat endpoint. Ownership is proven by the spec''s own contents: info.contact.name "VoyantIO", info.contact.url
    https://voyant.io, and a first-party servers[] host. IMPORTANT — the declared production host `gypsum.voyant.io` does
    NOT resolve (NXDOMAIN from both 8.8.8.8 and 1.1.1.1, while the apex voyant.io resolves to 76.76.21.21), so this contract
    is real and first-party but currently has no callable address. The spec declares no securitySchemes at all; auth is described
    in prose only, as a `user_id` query parameter carrying the Clerk organization ID.'
