go-mcp-server-mds
Provides a Go-based MCP (Model Context Protocol) server that exposes markdown files from a local filesystem (via fs.FS) as MCP resources (file:// URIs) and tools to list and read markdown files. Supports YAML (---) and TOML (+++) frontmatter parsing and returns frontmatter metadata in tool outputs/resource descriptions.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Likely self-hosted over stdio (no TLS/auth in README). This reduces network attack surface but does not address authorization or filesystem safety. No information is provided about path traversal protection, input validation, logging of sensitive data, or dependency vulnerability status.
⚡ Reliability
Best When
Running locally or in a controlled internal environment where the agent only needs to read markdown from a known directory; filesystem contents are considered non-sensitive or already access-controlled by infrastructure.
Avoid When
When you need strong authentication/authorization, audit logging, or safe handling of untrusted file paths/contents in a multi-user environment.
Use Cases
- • Expose a directory of markdown docs to an MCP-capable agent as retrievable resources
- • Let agents list available markdown documents with basic metadata (size/frontmatter)
- • Retrieve full markdown content plus parsed frontmatter for downstream summarization/Q&A
- • Build local/offline knowledge bases backed by filesystem content
- • Create lightweight document-serving MCP servers for internal tooling
Not For
- • Serving sensitive or access-controlled documents without additional isolation (no auth described)
- • Multi-tenant or internet-facing deployments without a reverse proxy/WAF and strict filesystem scoping
- • High-scale workloads requiring rate-limit guarantees or caching semantics (not documented)
- • Replacing a proper CMS/search index for large corpora
Interface
Authentication
No authentication or authorization mechanism is mentioned in the provided README; access is effectively determined by where/ how you run the server (stdio transport).
Pricing
No pricing model applies for a self-hosted open-source Go library/binary.
Agent Metadata
Known Gotchas
- ⚠ File path scoping/sanitization behavior is not described; agents should rely on the server to map URIs safely.
- ⚠ No auth described; ensure transport and execution context limit who can connect/call the server.
- ⚠ Frontmatter parsing delimiters are strict (YAML: --- , TOML: +++); malformed delimiters may lead to missing/invalid metadata depending on implementation.
