opgen-mcp-server
An MCP server that exposes tools for generating passwords/phrases (character-based and word-based) and copies the generated password to the clipboard.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
The tool generates passwords and copies them to the clipboard, which increases exposure risk (clipboard can be read by other processes/users). The provided docs include no details on TLS, auth, audit logging, or secure RNG practices; thus security-relevant guarantees cannot be confirmed from the README.
⚡ Reliability
Best When
You want an agent-callable password generator with simple local deployment (Go) and clipboard output.
Avoid When
You cannot allow clipboard writes (e.g., locked-down systems, high security contexts where clipboard exfiltration is a concern) or you need enterprise policy enforcement/auditing.
Use Cases
- • Generate strong random passwords with configurable length and character sets
- • Create passphrases from word lists or syllables with configurable separators and capitalization
- • Use password generation via an MCP-capable agent/workflow
Not For
- • Managing existing credentials/password vaults
- • Decrypting/storing sensitive secrets (it only generates and copies to clipboard per README)
- • High-assurance security workflows that require audit logs, policies, or external secret management
Interface
Authentication
No authentication/authorization details are described in the provided README.
Pricing
No pricing information provided (appears to be a self-hosted Go tool).
Agent Metadata
Known Gotchas
- ⚠ Generated passwords are copied to clipboard; agents should be aware of side effects and potential clipboard access policies.
- ⚠ No stated rate-limit or throttling behavior for MCP tools in the provided documentation.
- ⚠ No authentication details—if required by implementation, agents may fail without guidance.
