Use Charta Visa from inside your assistant

Connect in one step

Server URL (streamable HTTP, no auth):

https://chartavisa.com/api/v1/agent/mcp

claude mcp add --transport http charta-visa https://chartavisa.com/api/v1/agent/mcp

{
  "mcpServers": {
    "charta-visa": { "url": "https://chartavisa.com/api/v1/agent/mcp" }
  }
}

Try it

Once connected, ask your assistant things like:

• “Does a Kuwaiti citizen need a visa for the UK? What does it cost?”
• “Quote a rush ESTA for two Japanese travelers in euros.”
• “I’m Colombian and visiting Madrid, London and Miami in March — what authorizations do I need?” (the plan_my_trip prompt)
• “Prepare me for my US B1/B2 interview.” (the prepare_us_interview prompt + our guides as MCP resources)

Tool results lead with a plain-language answer and include ready-to-share links to the requirements page and the guided application — with promo code AGENT10 (10% off the Charta Visa service fee, never the government fee) prefilled.

Tools

Guest mode covers eligibility → quote → checkout → submit with the traveler's email. Account tools (status, profiles, webhooks, refunds) need an API key: self-issue a sandbox key with POST https://chartavisa.com/api/v1/agent/keys; live keys appear in the dashboard after the first paid checkout.

Public read endpoints (no key)

Six read-only endpoints are open to anyone — no API key, no sign-up, CORS enabled, so they work from a browser, a directory listing or an LLM tool definition: POST /eligibility, POST /quote, GET /schemas, GET /capabilities, GET /health and GET /discovery (all under /api/v1/agent). 30 requests/minute per IP. Payment, filing and account endpoints keep requiring an API key or agent headers.
