mozisu-mcp-server
An MCP server (and companion CLI/webserver) that counts characters in input text—returning total characters (including spaces) and non-space characters—with support for multi-byte Unicode like Japanese and emojis.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security posture is largely unclear from README. No authentication is documented; MCP/CLI appear local. Webserver binds to localhost per README, which reduces exposure, but TLS/auth configuration is not described. Dependency hygiene cannot be verified from provided content; MIT/Go repo suggests typical risks but no CVE status is provided.
⚡ Reliability
Best When
You need deterministic local character counting (Unicode-aware) and want to expose it to an LLM via MCP (e.g., Claude Desktop).
Avoid When
You need robust, documented operational behavior (rate limits, auth, error codes) or remote multi-tenant exposure.
Use Cases
- • Enabling LLMs to generate text constrained to exact character counts (e.g., social posts, product titles)
- • Validating/estimating character counts for Japanese/Unicode text
- • Providing a local utility (CLI) or lightweight UI (webserver) for character counting
Not For
- • Server-side shared usage without access controls (no auth described)
- • Use as a general text analytics platform beyond character counting
- • Production deployment where reliability/SLA and operational guidance are required
Interface
Authentication
README shows local execution for MCP/CLI and a local webserver on localhost:8080, with no authentication/authorization configuration described.
Pricing
No pricing information provided; repository appears open-source (MIT).
Agent Metadata
Known Gotchas
- ⚠ README does not specify exact MCP tool schema (tool name, parameters, response fields) beyond mentioning `count_characters`, so an agent may require inspection of the server code to map the full contract.
- ⚠ No rate limiting or timeout behavior is documented.
- ⚠ Webserver/auth not described; if exposed beyond localhost, access control may be needed by the deployer.
