Available components
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 →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (98 of 102), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (98 of 102), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 21 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability64
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 948 tokens (~158/item across 6 items; 6 tools + 0 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 Management27
- Stability observed for 8 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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The dependency tree was only partially resolved, so these counts may be incomplete.
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.
tampermonkey.delete ~129
Delete a userscript by path. **Input:** - `path`: The script or resource path (<script-uuid>/source, <script-uuid>/storage or <script-uuid>/<external-resource-url>) **Output:** - `success`: true if script was deleted successfully - `error`: Error object if deletion failed (e.g., script not found)
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | The script or resource path (<script-uuid>/source, <script-uuid>/storage or <script-uuid>/<external-resource-url>) |
No output schema declared.
No examples provided.
tampermonkey.get ~164
Get the content of a specific userscript. **Input:** - `path`: The script path (from list operation) - `ifNotModifiedSince` (optional): Unix timestamp - only return if script was modified after this time **Output:** - `value`: The script source code - `lastModified`: Unix timestamp of last modification - `error`: Error object if script not found or concurrent edit detected
| Name | Type | Req | Description |
|---|---|---|---|
| ifNotModifiedSince | number | — | Unix timestamp - only return if script was modified after this time |
| path | string | yes | The script or resource path (<script-uuid>/source, <script-uuid>/storage or <script-uuid>/<external-resource-url> |
No output schema declared.

tampermonkey.get-connection-code ~227
REQUIRED FIRST STEP: Get the connection code to connect Tampermonkey Editors to the MCP server. **How it works:** The MCP server creates a WebSocket server that waits for Tampermonkey Editors to connect. You must call this tool FIRST to start the WebSocket server and get a connection code. Then enter the code in the Tampermonkey Editors extension - it will connect TO the MCP server. **Steps:** 1. Call this tool to get the connection code 2. Open Tampermonkey Editors extension in your browser 3. Enter the code in the extension popup 4. The extension connects to the MCP server's WebSocket 5. After connection, you can use tampermonkey.list, tampermonkey.get, tampermonkey.patch, tampermonkey.put, tampermonkey.delete **Output:** - `code`: The connection code to enter in Tampermonkey Editors
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
tampermonkey.list ~152
List all userscripts available in Tampermonkey. **Input:** - `pattern` (optional): Filter scripts by name pattern - `includePattern` (optional): Filter scripts by include URL pattern **Output:** Array of userscript metadata including: - `name`: Script name - `namespace`: Script namespace - `path`: Script path (used for get/patch operations) - `requires`: List of @require dependencies - `storage`: Storage path (if any)
| Name | Type | Req | Description |
|---|---|---|---|
| includePattern | array | — | Filter scripts by include URL pattern |
| pattern | string | — | Filter scripts by name pattern |
