## Findings

- **info** The word "credentials" in `get_workflow` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "Credentials".

description: "...and its input_schema and output_schema. Credentials are never included."
```

- **info** The word "credentials" in `save_workflow` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...nce them by name, never with a URL or a credential. Read the current definition with get_w..."
```


## Deletes or cancels (3)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_run`

- The name "cancel_run" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel a run that has not finished. Work already done is billed. Cancelling a finished run changes nothing.
```

### `delete_schedule`

- The name "delete_schedule" says "delete": a word for removing or ending something.
- The description says "Permanently delete".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Permanently delete a schedule. Needs an administrator key. Runs it already started are not affected. To stop it for a while, pause it with update_schedule instead.
```

### `delete_workflow`

- The name "delete_workflow" says "delete": a word for removing or ending something.
- The description says "Permanently delete".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Permanently delete a saved workflow. Runs already started are not affected; schedules that use it stop being able to start runs until it is saved again.
```

## Changes things (5)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_run`

- The name "create_run" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Start an AI agent run in an isolated sandbox and return the run (status queued) at once. Give a prompt, or the name of a saved workflow. Poll with get_run or block with wait_for_run for the result. Every run has a cost cap (max_cost_micros) and a timeout, and is billed to the organization of the API key. Connections must already be saved in the organization; reference them by name. Use idempotency_key to make a retry safe. A run's cost_micros is provisional (usually above the final cost) until cost_final is true; see get_run. On the hosted service a run costs a run fee once its worker starts, compute per second, model calls at the provider's price plus a percentage, and web requests and searches at flat prices; `GET /v1/me` reports the rates.
```

### `create_schedule`

- The name "create_schedule" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start a saved workflow on a timetable. Needs an administrator key. Each start is a run billed to the organization, with the cost cap given here (or the default). Use preview_schedule first to check the timetable. A schedule pauses itself after repeated failed starts. An organization can have 50 schedules.
```

### `run_schedule`

- The name "run_schedule" says "run": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Start the schedule's workflow now, outside its timetable, with the schedule's input and cost cap. Returns the queued run (follow it with wait_for_run); each call starts another run and is billed like any run.
```

### `save_workflow`

- The name "save_workflow" says "save": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Create a workflow, or replace the one with this name (saving the same definition again changes nothing more). A workflow is a reusable run definition: start it with create_run and its name, or on a timetable with create_schedule. Connections must already be saved in the organization; reference them by name, never with a URL or a credential. Read the current definition with get_workflow first when you change part of it, because saving replaces the whole definition. Give it a description, and an input_schema and output_schema (JSON Schemas) so that agents can discover and call it: a run's input is checked against input_schema before it starts, and its output must be JSON matching output_schema or the run fails.
```

### `update_schedule`

- The name "update_schedule" says "update": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Change a schedule; only the fields you give change. Needs an administrator key. Set enabled to false to pause it and to true to resume it (resuming clears the failures that paused it). A new timetable counts from now.
```

## Only reads (11)

Looks things up and changes nothing. Claude Code: allow.

### `get_run`

- The name "get_run" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a run: status, output, error, cost and billing_pending. COST: while billing_pending is true (or the run is still going), cost_micros is PROVISIONAL and usually higher than the final cost; the result then has cost_final:false and a cost_note. Quote a cost only when cost_final is true (the run is finished and billing_pending is false); otherwise call get_run again in a few seconds. For a zero-data-retention run the first read of a finished run returns the output and then deletes it. On the hosted service a run costs a run fee once its worker starts, compute per second, model calls at the provider's price plus a percentage, and web requests and searches at flat prices; `GET /v1/me` reports the rates.
```

### `get_schedule`

- The name "get_schedule" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a schedule: timetable, time zone, input, cost cap, whether it is enabled, its next start and the outcome of its last start.
```

### `get_workflow`

- The name "get_workflow" says "get": a word for reading.
- Tag private-data: The description's first sentence says "read" and "file": it reads files.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Read a saved workflow's definition: description, prompt, model, files, connections, limits and its input_schema and output_schema. Credentials are never included.
```

### `list_connections`

- The name "list_connections" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The organization's saved connections that a run may use, with type, allowed methods and tools. No URLs or secrets are returned. Reference one in create_run by name.
```

### `list_files`

- The name "list_files" says "list": a word for reading.
- Tag private-data: The name "list_files" says "list" and "file": it reads files. The description's first sentence says "list" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
List the files saved in the organization: id, name, size, content type and creation time. Reference a file by id in a run's or workflow's files. Read-only; upload and delete files through the REST API.
```

### `list_models`

- The name "list_models" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find models. Returns a compact list (id, name, context_length, input and output USD per million tokens, zero_data_retention where known), the total count and the default model. There are hundreds of models, so filter with query (case-insensitive part of the id or name, e.g. "claude", "gpt") and read the hint when the list is truncated (default 25, at most 100). Pass model for one model's full details. Use an id from it as create_run's model.
```

### `list_runs`

- The name "list_runs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the organization's runs, newest first, with a cursor for the next page. Each run has cost_final: when false, cost_micros is provisional (usually above the final cost) and billing is still settling.
```

### `list_schedules`

- The name "list_schedules" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the organization's schedules: each starts a saved workflow on a cron timetable. Includes the next start, the last run and the last error.
```

### `list_workflows`

- The name "list_workflows" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the organization's saved workflows (reusable run definitions). Each entry has the workflow's name and, when set, its description, input_schema (the shape of the input create_run expects) and output_schema (the shape of the JSON it returns), so you can call a workflow without reading its prompt. Run one with create_run and its name.
```

### `preview_schedule`

- The name "preview_schedule" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check a cron expression and time zone and return the next five start times (UTC), without saving anything.
```

### `wait_for_run`

- The name "wait_for_run" says "wait": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Wait until a run finishes (succeeded, failed, cancelled, interrupted or timed_out) or the wait ends, then return the run. After the run finishes it keeps waiting, within the same time, until billing has settled (billing_pending false, normally a few seconds to about 20), so the cost is final. Waits at most 60 seconds; if the run is still going, the returned status says so and you can call it again. COST: if the result has cost_final:false, cost_micros is PROVISIONAL and usually higher than the final cost; do not quote it, call get_run again shortly. Quote the cost only when cost_final is true.
```
