Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security94
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1833 tokens (~73/item across 25 items; 25 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage80
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 29% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

grant_connector Grant connector to app ~131
Gives one of your apps access to a connector. The app can then call the connector's operations. Note: this lets the app's code, and everyone the app is shared with, use the connector's credential. A connector an admin has marked admins-only can only be granted by an admin. Some connectors require admin approval: when a creator grants one of those, the grant is created as 'requested' and an owner/admin must approve it (they're emailed) before the app can use it — owners/admins granting it are approved automatically.

propose_connector Propose connector ~192
Creates a new API connector as a DRAFT from the vendor's API docs: you supply the base URL, auth style, and an operations manifest. A workspace member (owner, admin, or creator) then opens the panel and adds the credential to activate it — the credential never passes through you. auth_style is bearer|header|query|basic; for header/query also give auth_param (the header/param name).

| string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|

| deploy_job | integer | – | – |
| status | string | – | – |
No examples provided.
set_database_sharing Set database sharing ~151
Turns this app's database sharing on or off. Off by default (the database is private). When on, other apps in the same workspace may read AND write this app's SQLite database through Croft's internal broker at http://croft-data:8080/q/<this-app-name> (send {"sql":"…","params":[…]}), and this app is listed to other apps as reusable shared data. Turn it on for an app whose data other apps should reuse — e.g. a CRM's contacts list that an invoicing app also needs.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| shared | boolean | yes | true to share this app's database with the workspace; false to keep it private. |
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | – | – |
| shared | boolean | – | – |
No examples provided.
set_public_paths Set public paths ~126
Sets which of an app's paths are reachable WITHOUT login. By default an app is fully private (workspace login required everywhere). Pass the complete desired list of specific paths (e.g. ["/survey"]); each listed path and everything under it becomes public, everything else stays private. An empty list makes the app fully private again. The whole app cannot be made public — root or wildcard paths are rejected.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| paths | array | yes | Full list of public paths, each starting with / (e.g. "/survey"). Empty to make fully private. |
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | – | – |
| public | boolean | – | – |
| public_paths | array | – | – |
No examples provided.
set_schedules Set scheduled tasks ~135
Sets the app's scheduled tasks. Each is { name, cron, path }: on the cron (standard 5-field, UTC) Croft makes an internal POST to the app's path, and the app does the work (e.g. send a daily email, sync an API). Use this for anything recurring instead of writing your own cron — it survives deploys and reboots and is shown in the panel. Also implement the endpoint (e.g. a POST route at that path). Pass the full desired list; an empty list clears all schedules.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| schedules | array | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | – | – |

No examples provided.
set_secret Set secret ~50
Set (or replace) an env secret for an app. Value is stored encrypted and injected at deploy.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| key | string | yes | – |
| value | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | – | – |
| ok | boolean | – | – |
No examples provided.
status App status ~83
Reports an app's deploy and health status. `live` is true only when the latest deploy has fully succeeded; `deploy_state` gives the current stage (queued, running, succeeded, or failed). Read-only and safe to call repeatedly — each call returns the current stage, so it can be polled to follow a deploy's progress.
| Name | Type | Req | Description |
|---|---|---|---|
| app | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|

| shared | boolean | – | – |
| url | string | – | – |
No examples provided.
write_files Write files ~72
Writes files into an app's git repo and commits them (as 'Claude via Croft'). files is a list of {path, content}. Committed files are staged in the repo; they are not built or published until the app is deployed.
