mcp-mistral-ocr
Provides an MCP server that performs OCR using Mistral AI’s OCR API. It can process files from a mounted local directory (images/PDFs) and can process files from URLs when the caller supplies an explicit file type; results are written as timestamped JSON files inside an OCR output directory under the configured OCR_DIR.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS enforcement for outbound calls to Mistral/OCR endpoints is not described in the README (assumed by typical HTTPS usage, but not guaranteed). Auth is a single static MISTRAL_API_KEY with no per-user/per-tool scopes described. The README instructs passing the key via environment variables, which is generally safer than hard-coding, but no guidance is given about logging/redaction or handling sensitive contents. Dependency list is small but dependency CVE hygiene cannot be confirmed from provided data.
⚡ Reliability
Best When
You want a simple MCP-based OCR capability integrated into desktop/agent tooling, using Docker and a single Mistral API key.
Avoid When
You need clear, documented operational guarantees (retries, error codes, rate limit headers) or fine-grained authorization/scopes for multi-tenant deployments.
Use Cases
- • Extract text from scanned documents (PDF/image) via an MCP tool
- • OCR for documents stored in a local volume mounted into the container
- • OCR for publicly reachable documents/images via URL + explicit file_type
- • Integrating OCR into Claude Desktop workflows using MCP
Not For
- • Performing OCR without user-provided access to images/PDFs (e.g., arbitrary private URLs not reachable by the server)
- • High-volume/real-time interactive OCR where strict latency/throughput SLAs are required
- • Use cases that need strong built-in access controls per user beyond holding an API key
- • Workflows requiring documented rate-limit behavior, retries, and idempotency guarantees at the MCP layer (not specified)
Interface
Authentication
Authentication is via a single Mistral API key passed to the container via environment variable (no OAuth or per-tool scopes described).
Pricing
The MCP server itself is open-source (MIT per metadata), but OCR calls incur Mistral OCR API costs. No cost calculator or tiers are described in the README.
Agent Metadata
Known Gotchas
- ⚠ process_local_file requires the file to be present in the mounted OCR_DIR container path (mapped to /data/ocr in the README example).
- ⚠ process_url_file requires explicit file_type ('image' or 'pdf'); agents must supply it correctly.
- ⚠ Large inputs are limited by Mistral API constraints (50MB and up to 1000 pages); agents should pre-check or handle failures.
