What is linkwarden-mcp-server CLAUDE.md?

Project instructions for a Go-based MCP server that gives AI assistants programmatic access to Linkwarden, a bookmark-management service. They describe the project structure, development commands, testing, building, and SDK generation.

Developing the Linkwarden server, running unit or integration tests, checking code quality, formatting code, generating its SDK, and building or installing the binary.

They give an agent the repository context and the commands needed to work on the server consistently. This reduces guesswork when building, testing, formatting, or linting the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01528	$0.01528
Opus 5.5	$0.00611	$0.00611
Sonnet 5.5	$0.00306	$0.00306

Security

Grade A, and why

linkwarden-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This is a Go-based MCP (Model Context Protocol) server that provides AI assistants with programmatic access to Linkwarden instances. The server implements a modular toolset system for managing bookmark collections, links, tags, searching, and accessing public collections.

Architecture

Core Components

MCP Server (cmd/linkwarden-mcp-server/main.go)
- Entry point with Cobra CLI
- Configuration management using Viper
- Stdio transport implementation
- Signal handling and graceful shutdown
Toolset System (pkg/toolsets/)
- Modular organization of functionality
- Read/write separation for safety
- Selective toolset enabling
- Global read-only mode support
Tool Implementation (pkg/linkwardenmcp/)
- Individual MCP tools with validation
- Type-safe parameter handling
- Linkwarden API integration
- Comprehensive error handling
API Client (pkg/linkwarden/)
- Auto-generated from OpenAPI spec
- Type-safe HTTP client
- Authentication handling

Key Architectural Patterns

Toolset Registration: Tools are organized into toolsets (search, collection, link, tags) that can be selectively enabled
Parameter Validation: Comprehensive validation system in tools_param.go with type safety
Read/Write Separation: Each toolset supports read-only mode for production safety
Configuration Flexibility: Supports command-line flags, environment variables, and config files
Observability: Structured logging with context-aware logging

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
