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 Security99
- 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
- 33 of 134 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency19
- Repository check failed: the declared repository URL redirects; it must resolve directly. See how to fix → View diagnostics → Fail
- 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 207 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability79
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 670 tokens (~67/item across 10 items; 10 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass

- 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
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "vault_remove" implies "remove" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
vault_add ~121
Securely add a new credential to the vault. Opens a browser form where the user enters their password directly — the password NEVER passes through the AI agent. Supports templates for popular services (github, jira, stripe, etc.).
| Name | Type | Req | Description |
|---|---|---|---|
| service_type | string | – | Type of credential (default: web_login, or from template) |
| session_scoped | boolean | – | If true, credential auto-deletes when MCP session ends |
| site_id | string | – | Pre-fill the site identifier (e.g. "github"). If a template exists, selectors auto-fill. |
No output schema declared.
No examples provided.
vault_api_request ~140
Make an API request with stored credentials. The API key is injected automatically — the bot never sees it. Supports header, query param, and basic auth patterns.
| Name | Type | Req | Description |
|---|---|---|---|
| auth_type | string | – | Auth pattern: "header" (default), "query" (append key as URL param), "basic" (HTTP Basic Auth) |
| body | string | – | Request body (JSON string) |
| headers | object | – | Additional headers |
| method | string | – | HTTP method (default: GET) |
| service | string | yes | The service identifier (e.g. "openai", "stripe") |
| url | string | yes | The API endpoint URL |
No output schema declared.
No examples provided.
vault_check ~43
Verify a credential is valid and ready to use. Checks existence, active status, required fields, and expiration.
| Name | Type | Req | Description |
|---|---|---|---|
| site_id | string | yes | The site identifier to check |
No output schema declared.
No examples provided.
vault_import ~101
Import API keys from a .env file. Each key is stored as an encrypted api_key credential. The .env values pass through memory only — never returned to the agent.
| Name | Type | Req | Description |
|---|---|---|---|
| file_path | string | yes | Path to the .env file |
| mapping | object | – | Map .env variable names to site IDs, e.g. {"STRIPE_KEY": "stripe", "OPENAI_KEY": "openai"}. If omitted, all variables are imported. |
No output schema declared.
No examples provided.
vault_list ~26
List all available credentials in the vault. Returns only site IDs and types — no secrets.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
vault_login ~100
Log into a website using stored credentials. The bot never sees the password — Vault fills the login form via Chrome DevTools Protocol. Supports TOTP 2FA if configured.
| Name | Type | Req | Description |
|---|---|---|---|
| site_id | string | yes | The site identifier (e.g. "github", "jira") |
| timeout_ms | number | – | Login timeout in milliseconds (default: 15000) |

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
vault_update ~46
Update an existing credential. Opens a browser form to enter new password/API key — the secret NEVER passes through the AI agent.
