Configures as an MCP server for GitHub Copilot in VS Code, providing 12 intelligent tools that reduce Codebeamer API calls by 70-98% through CbQL queries, caching, and rate limiting for efficient project, tracker, and item management.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g.,@Codebeamer MCP Server what is the weather in Tokyo?
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
You can also use deployed servers via HTTP endpoints. For instructions, see How to Test MCP Streamable HTTP Endpoints Using cURL.
π Codebeamer MCP Server
Efficient MCP (Model Context Protocol) server for Codebeamer V3 APIs
Transform 30+ individual API calls into 12 intelligent tools that reduce API calls by 70-98% with built-in caching and rate limiting.
β‘ Quick Start
π― What Problem Does This Solve?
β Before (Individual API Tools)
30+ separate API tools for different operations
Agent struggles with wrong tool selection
Sequential API calls (get_projects β get_trackers β get_items...)
Rate limiting issues from too many calls
Slow performance (25+ API calls for simple queries)
No caching - redundant requests
β After (Smart MCP Tools)
12 intelligent tools that combine operations
Clear, purpose-driven tool selection
Single CbQL queries replace sequential calls
Built-in rate limiter prevents throttling
70-98% fewer API calls for same operations
85%+ cache hit rate - smart caching
π Performance Comparison
Operation | Old Approach | Smart Tool | Improvement |
Find 100 bugs across 5 projects | 25 API calls | 1 API call | 96% β |
Get project with all data | 50+ API calls | 3 API calls | 94% β |
Update 20 items | 20 API calls | 1 API call | 95% β |
Get 10 specific items | 10 API calls | 1 API call | 90% β |
Sprint report generation | ~50 API calls | 1 API call | 98% β |
Result: Faster, more reliable, rate-limit safe! β‘
π οΈ The 12 MCP Tools
π Query & Retrieval (90% of use cases)
codebeamer_query_itemsβ Most ImportantUse CbQL to query items across projects/trackers
Replaces: get_projects β get_trackers β get_items chain
96% API reduction (1 call instead of 25+)
codebeamer_get_project_completeGet full project data (trackers + items)
94% API reduction (3 calls instead of 50+)
codebeamer_get_tracker_completeGet full tracker data with all items
92% API reduction
codebeamer_get_items_batchGet multiple items by IDs in one call
90% API reduction
codebeamer_get_item_with_contextGet item + children + relations + parent
75% API reduction
βοΈ Create & Update
codebeamer_create_itemCreate new tracker items
codebeamer_update_itemUpdate item fields with cache invalidation
codebeamer_bulk_update_itemsBulk update multiple items
95% API reduction (1 call instead of N)
π Relations & Structure
codebeamer_manage_associationsCreate, get, or delete item associations
codebeamer_get_hierarchy_treeGet hierarchical tree structure
80% API reduction
π Monitoring
codebeamer_get_statsView API usage, cache hits, performance
codebeamer_clear_cacheRefresh cached data when needed

π§ Configuration Options
Environment Variables
Cache TTL Guidelines
60s - Frequently changing data (current sprint items)
300s (default) - Normal data
3600s - Rarely changing data (field metadata, archived items)
π Troubleshooting
"CODEBEAMER_API_KEY is required"
Set the environment variable before running.
Rate limiting errors
Reduce CODEBEAMER_MAX_CALLS to 30 or lower.
Stale cached data
Use codebeamer_clear_cache tool to refresh.
Connection timeout
Verify CODEBEAMER_URL and network connectivity.
π Statistics & Monitoring
The tool automatically tracks:
API calls made - Total API requests
Cache hits/misses - Caching efficiency
Cache hit rate - Percentage of cached responses
Remaining calls - Calls left in current minute
Cache size - Number of cached entries
Access via codebeamer_get_stats tool.
