Drishti × MCP.

Drishti speaks the MCP HTTP transport with OAuth 2.1 + PKCE — the same Custom Connector contract Anthropic ships in Claude.ai. Paste the URL, sign in, approve the consent screen, done. No API key to copy around, no header to configure. For Claude Code and other terminal clients you can still use a static Bearer key.

    }
  }
}

The initialize and tools/list methods are open — your client can register the server and discover the tool list before you paste a token. Token-required tools fail with -32001 Unauthorized until the header is in place.

A mock transcript of the smallest useful workflow: the agent introspects the server, picks the right mode, kicks off a generation, and surfaces the queued ID for polling.

Every tool is callable via tools/call. The dispatcher parses arguments through a zod schema before reaching the handler — invalid shapes fail at the edge with -32602 and the failing field path inside data.

Drishti API keys carry a scope array. The dispatcher checks the requested tool against the key's scope set before reaching the handler — a key without generate can browse modes and recent runs but cannot debit credits.

New keys default to a balanced set: ["read:gens", "read:vault", "generate"]. Add write:vault for agentic workflows that need to push references; reserve admin:webhooks for the keys you trust with delivery secrets.

Twenty-three tools, eight prompts, OAuth 2.1, and inline image rendering all ship today. The gaps below are the surfaces we've already designed but not yet wired up — none of them block the workflows the current tools already cover.

• Webhook subscriptions

  generation.shipped · generation.refunded · brand.completeness.changed. HMAC-SHA-256 signed. Replayable from the workspace dashboard.

• Streaming responses

  MCP's SSE transport for long-running tools (especially chaos_start which fans out to 18 parallel runs). Until then, poll list_recent or wait_for_generation.

• Resource subscriptions

  `drishti://modes`, `drishti://workspace`, `drishti://brands`, and `drishti://recent` ship as readable resources today. Live subscription (resources/updated push) is the next step — until then, clients re-read on demand.

• Marketplace export presets

  Amazon · Flipkart · Myntra · Meesho profile-driven export with platform-specific aspect ratios + EXIF stripping. Today marketplace_export is a no-op stub.

Static API keys + OAuth 2.1 Custom Connector both work today. Mail admin@indigenservices.in for early access to the webhook + streaming preview.
