How onozaty/redmine-mcp-server configures Claude Code

Q: What is redmine-mcp-server CLAUDE.md?

A project guide for an MCP server that lets AI assistants access Redmine, a project-management and issue-tracking system, through its REST API.

Q: What is it for?

Use it to understand the Redmine API handlers, attachment uploads and downloads, configuration, and TypeScript code-generation workflow.

Q: Why use it?

It explains the generated code, custom file attachments, configuration, and read-only options so agents can work in the right layer.

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	$0.00866	$0.00866
Opus 5	$0.00433	$0.00433
Sonnet 5	$0.00173	$0.00173
Haiku 4.5	$0.00087	$0.00087

Security

Grade A, and why

redmine-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 9d 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 Model Context Protocol (MCP) server for Redmine that provides comprehensive access to Redmine's REST API. The server automatically generates TypeScript handlers and schemas from a Redmine OpenAPI specification and extends them with custom attachment file handling capabilities.

Architecture

Core Components

Generated API Layer: Located in src/__generated__/ (auto-generated, don't edit directly)
- handlers.ts - MCP tool handlers for each Redmine API endpoint
- http-schemas/ - Zod schemas for API requests/responses
- tool-schemas.zod.js - Tool parameter schemas
- http-client.ts - HTTP client with custom fetch integration
Custom Extensions: Located in src/attachment/
- File upload/download handlers that extend the generated API
- Thumbnail download functionality
- Direct file I/O operations with Redmine
Configuration: src/config.ts
- Environment-based configuration loading
- Read-only mode support via REDMINE_MCP_READ_ONLY=true
- Tool filtering via REDMINE_MCP_TOOLS_ALLOW_PATTERN and REDMINE_MCP_TOOLS_DENY_PATTERN
- Requires REDMINE_URL and REDMINE_API_KEY environment variables
Main Server: src/server.ts
- Registers all tools with read-only/write classification
- Implements conditional tool registration based on configuration (read-only mode and regex filters)
- Extensive tool registry covering all Redmine operations

Code Generation Workflow

OpenAPI Specification: redmine-openapi.yaml defines the Redmine API
Orval Configuration: orval.config.ts configures code generation
Generated Code: pnpm gen creates handlers and schemas in src/__generated__/
Post-Processing: post-generate.js adds custom fetch import to generated HTTP client

Development Commands

# Generate API code from OpenAPI spec
pnpm gen

# Build the project (includes generation)
pnpm build

# Build for publishing
pnpm prepublishOnly

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.
