Category Version Control
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to jmrplens/gitlab-mcp-server). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 3 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1289 tokens (~128/item across 10 items; 2 tools + 8 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management70
- Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
gitlab_execute_action GitLab Execute Action ~158
Execute one GitLab catalog action by canonical ID or alias. Always pass params as an object. Destructive actions require top-level confirm=true. Use find first only when action or params are unclear. Example: {"action":"issue.list","params":{"project_id":"group/project"}}
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | Canonical action ID returned by gitlab_find_action, or a supported compatibility alias, such as project.list, issue.update, or issue.close. |
| confirm | boolean | – | Set top-level confirm=true to explicitly approve destructive actions. Do not put confirm inside params for gitlab_execute_action. |
| params | object | yes | Required action-specific parameters object validated by the selected action schema. Use an empty object for actions with no parameters. |
| Name | Type | Req | Description |
|---|---|---|---|
| next_steps | array | – | Optional. Suggested follow-up actions or tool calls for the LLM, contextual to the result. |
| pagination | object | – | Present on list actions. A REST list carries the fields below: while `has_more` is true, call again with `page` set to `next_page`, or on a keyset page with `page_token` set to `next_page_token`. A G… |

gitlab_find_action GitLab Find Action ~166
Search the local GitLab action catalog. Read-only and no GitLab API call. Use when the action ID or params are unclear. Returns schemas, hints, destructive flags, and execute examples. Example: {"query":"issue list"}
| Name | Type | Req | Description |
|---|---|---|---|
| explain | boolean | – | When true, include deterministic scoring reasons for each returned action. Defaults to false to keep responses compact. |
| limit | integer | – | Maximum number of matches to return. Defaults to 20 and is capped at 50. |
| query | string | yes | Search terms combining a GitLab domain or resource with a verb, filter, or object name, such as project create, merge request approve, pipeline retry, issue delete, or ci variable. At most 256 charac… |
| Name | Type | Req | Description |
