xliff-mcp-server
Provides an MCP server (Python) exposing tools to parse, validate, extract, and manipulate XLIFF and TMX localization files, including tag-preserving processing, replacement of XLIFF targets from translated content, and CSV/JSON exports. Also ships a skills/catalog workflow layer intended for agent-guided localization tasks.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security characteristics are largely unknown from the provided content. TLS/auth are not discussed; if deployed remotely, transport security and access control must be handled by the host/container/network. The package is MIT-licensed and uses common Python libraries; specific dependency vulnerabilities/CVE posture is not provided. Since MCP runs as a local process (per README), secrets are likely not required, but input data handling and logging behavior are not documented.
⚡ Reliability
Best When
You have local XLIFF/TMX content and want an agent-accessible, tool-based workflow to parse/validate/transform it (including tag-safe workflows).
Avoid When
You need strong API-level security controls (auth, scopes, rate limiting) provided out of the box, or you require a hosted endpoint with documented SLAs.
Use Cases
- • Extract translation units from XLIFF files for review or machine translation
- • Extract translation units from TMX translation memory files
- • Validate XLIFF/TMX inputs before processing
- • Preserve inline formatting/tags in XLIFF while preparing content for AI translation
- • Replace XLIFF target segments using structured translation results (segNumber/unitId mapping)
- • Export XLIFF/TMX to CSV or JSON for downstream tooling
Not For
- • Running as a secure hosted SaaS without additional deployment hardening (auth/rate limiting not described)
- • Handling extremely large files without confirmed streaming/memory safeguards (not documented)
- • Using as a general translation service (it processes files; translation generation is out of scope)
Interface
Authentication
No authentication mechanism is described for the MCP server. The README shows local process invocation (e.g., Claude Desktop command/args), implying access is controlled externally by your environment rather than via server auth.
Pricing
No pricing information is provided (likely open-source with self-hosted/local execution).
Agent Metadata
Known Gotchas
- ⚠ Replacement-style tools likely require correct segNumber/unitId alignment; mismatches may lead to partial or incorrect updates.
- ⚠ Tag-preserving workflows require that inline tags are handled exactly as expected by the XLIFF structure; malformed inputs can break processing.
- ⚠ No rate-limit or concurrency guidance is documented for MCP tool calls.
