EnriVision
EnriVision is a Model Context Protocol (MCP) server over stdio that uploads local media to EnriProxy and returns server-side extraction + model analysis.
This is useful for media types that many MCP clients cannot read reliably (videos, audio, scanned PDFs, HEIC/AVIF, large files), while keeping the MCP server itself lightweight.
What this project is
- An MCP server process your MCP host launches (OpenCode, Claude Code, Codex, etc.)
- A thin client for EnriProxy (resumable upload + structured output)
Requirements
- Node.js
>= 22(recommended: Node 24 LTS) - A reachable EnriProxy server with these endpoints enabled:
POST /v1/uploadsHEAD /v1/uploads/:idPATCH /v1/uploads/:idPOST /v1/vision/analyze
- An EnriProxy API key (configured on the EnriProxy side)
Install
# Global install
npm install -g @bedolla/enrivision
# Or run without installing
npx -y @bedolla/enrivision@latest --help
Build
npm install
npm run typecheck
npm run build
Usage
1) Configure your MCP host
EnriVision runs as an MCP server over stdio. Your MCP host is responsible for launching the process.
Example: global install
{
"EnriVision": {
"type": "stdio",
"command": "enrivision",
"args": [],
"env": {
"ENRIPROXY_URL": "http://127.0.0.1:8787",
"ENRIPROXY_API_KEY": "YOUR_ENRIPROXY_API_KEY",
"ENRIVISION_DEFAULT_LANGUAGE": "es"
}
}
}
Example: no install (always uses whatever npm currently tags as latest)
{
"EnriVision": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@bedolla/enrivision@latest"],
"env": {
"ENRIPROXY_URL": "http://127.0.0.1:8787",
"ENRIPROXY_API_KEY": "YOUR_ENRIPROXY_API_KEY",
"ENRIVISION_DEFAULT_LANGUAGE": "es"
}
}
}
Use a local dev checkout
{
"EnriVision": {
"type": "stdio",
"command": "node",
"args": ["C:\\\\Users\\\\Administrator\\\\Projects\\\\EnriVision\\\\dist\\\\index.js"],
"env": {
"ENRIPROXY_URL": "http://127.0.0.1:8787",
"ENRIPROXY_API_KEY": "YOUR_ENRIPROXY_API_KEY",
"ENRIVISION_DEFAULT_LANGUAGE": "es"
}
}
}
Configuration
EnriVision is configured via environment variables:
ENRIPROXY_URL(string, optional, default:http://127.0.0.1:8787)ENRIPROXY_API_KEY(string, required)ENRIVISION_TIMEOUT_MS(string, optional, default:1800000)- Parsed as an integer (milliseconds). Uploads are performed in chunks; this timeout applies per request.
ENRIVISION_DEFAULT_LANGUAGE(string, optional)- Default language to send when the tool call does not provide
language.
- Default language to send when the tool call does not provide
MCP tools
EnriVision exposes this MCP tool:
analyze_media
Tool inputs (option-by-option)
General notes:
- The tool accepts a single JSON object as its input (the MCP
arguments). - Exactly one of
pathorpathsis required. - Paths must be absolute on the machine running the MCP server.
- EnriVision does not accept per-call
server_url/api_keyoverrides (these are configured via env vars).
`analyze_media`
Inputs:
path(string, optional): absolute local file path.paths(string[], optional): absolute local image paths (useful for UI screenshot sets).context(string, optional): high-level hint (examples:ui,diagram,chart,error,code,meeting,tutorial,photo).question(string, optional): what you want to extract/answer.language(string, optional): preferred response language (ISO 639-1; e.g.,es,en).

Video targeting:
video.clip_start_seconds(number, optional)video.clip_duration_seconds(number, optional)
Multipass tuning (advanced; used only for analysis_mode: multipass):
