pvv-mcp-server
A Python-based MCP server that exposes VOICEVOX text-to-speech capabilities (e.g., generic speaker speak, a specific Metan Aska-style tool, and a speakers list) by wrapping the VOICEVOX Web API using FastMCP.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No auth described; if exposed beyond localhost, it may be vulnerable. TLS expectations are not specified (likely local MCP/HTTP usage). Dependency hygiene appears moderate-to-good from version pins only; no CVE/security posture is documented. Ensure no secrets are logged by your surrounding infrastructure; this package’s logging/security behavior is not described.
⚡ Reliability
Best When
You run MCP + VOICEVOX locally (or in a controlled environment) and want agent-accessible TTS tools.
Avoid When
You need clear rate-limit/error-code contracts, strong auth, or stable, well-documented operational behavior for third-party callers.
Use Cases
- • Integrating VOICEVOX TTS into an MCP-compatible agent/workflow
- • Programmatic speech synthesis with configurable speaker IDs
- • Providing an MCP resource/tool for enumerating available VOICEVOX speakers
Not For
- • Production, internet-exposed services without additional security hardening/operations
- • Use cases requiring robust documented APIs, SLAs, or enterprise authentication/authorization
Interface
Authentication
No authentication mechanism is described in the provided README/manifest. Access is likely local-process based, but details are not documented.
Pricing
No pricing information applies (open-source library).
Agent Metadata
Known Gotchas
- ⚠ Requires Windows OS per README.
- ⚠ README states 'Claudeが起動していること' but does not specify configuration/ports/env vars; agent integration may require manual setup.
- ⚠ Tool/resource names and exact MCP input/output schemas are not shown in the provided README; agents may need to infer or inspect the code.
- ⚠ No documented rate limits or guidance for retry/backoff.
- ⚠ Depending on VOICEVOX setup, failures may occur if VOICEVOX Web API is not reachable.
