mcp-prompt-server-go
A Go-based MCP (Model Context Protocol) server that runs over stdio and exposes a set of prompt templates as MCP “tools”, including prompt management utilities (e.g., list available prompts, reload prompt definitions) with hot-reload from a local prompts directory.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Transport is stdio (local) rather than TLS/network; TLS enforcement is not applicable but remote exposure is not documented. No authentication/authorization or scope model is described. Secrets handling practices are not documented in the README. Dependency hygiene cannot be verified from provided content; score is based on lack of evidence rather than actual dependency scan results.
⚡ Reliability
Best When
Used as a local stdio MCP server by MCP-capable clients (e.g., Cursor/Windsurf/Raycast) to quickly integrate prompt templates as tools.
Avoid When
Avoid where you need robust, documented transport-layer security controls beyond stdio, or where you require strict operational guarantees (SLA, documented recovery/retry/idempotency semantics).
Use Cases
- • Local agent/tooling integration to discover and call prompt templates via MCP (tools/call).
- • Building higher-level agent workflows for content generation, summarization, and code assistance using parameterized prompt templates.
- • Development/debugging of prompt sets with live reload and tool discovery (get_prompt_names).
- • Automated generation of structured artifacts (e.g., PRDs, HTML snippets, code review/refactor suggestions) from templates.
Not For
- • Production-grade remote multi-tenant deployments requiring network endpoints, webhooks, or managed authentication/authorization.
- • Use cases needing first-class REST/GraphQL/SDK integrations, or strict enterprise compliance features documented by the project.
- • Use cases requiring documented rate limiting and usage guarantees across concurrent clients.
Interface
Authentication
No authentication mechanism is documented in the provided README. Integration appears intended for local usage via stdio.
Pricing
Repository README does not describe any pricing; as an open-source server it is presumably self-hosted.
Agent Metadata
Known Gotchas
- ⚠ No documented auth/rate limit semantics; agents should avoid assuming network-accessible or multi-tenant behavior.
- ⚠ Hot-reload may cause tool catalog changes during long-running sessions; agents should refresh tool discovery (e.g., get_prompt_names) if behavior changes are observed.
- ⚠ No documented structured error codes or retry guidance for MCP tool calls; agents should handle generic JSON-RPC/MCP failures robustly.
