## Findings

- **warn** Annotations that disagree with the tool in `flux_generate_keys` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "flux_generate_keys" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "flux_generate_keys" says "generate": a word for a change.
```

- **warn** Annotations that disagree with the tool in `flux_validate_spec` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "flux_validate_spec" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "flux_validate_spec" says "validate": a word for reading.
```


## Deletes or cancels (3)

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

### `flux_cancel_app`

- The name "flux_cancel_app" 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
Ends an app early by updating its term so it expires within about an hour. The network then uninstalls it everywhere. With confirm=true this signs and pays the (usually minimal) update; without it, returns the plan.
```

### `flux_control_app`

- The description's first verb is "restart": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
restart: restarts containers. redeploy: pulls the image again and recreates containers (hard=true also wipes data). remove: uninstalls from nodes; the registration stays and the network re-spawns it elsewhere, so use flux_cancel_app to stop paying. Scope is one node (nodeIp) or every node running the app (global). Requires the owner key.
```

### `flux_deploy_app`

- The name "flux_deploy_app" says "deploy": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Validates the specification on a node, quotes it, and with confirm=true signs it with the Flux ID, broadcasts it and pays the quoted FLUX from the payment address. Without confirm it only returns the plan (price, balance, warnings) and spends nothing. Registers a new name or updates an existing app of the same owner. Then call flux_wait_for_app with the returned txid.
```

## Changes things (3)

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

### `flux_build_spec`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Turns images, ports, resources and a term into a complete, correctly formatted v8 specification, with public ports auto-picked and data replication enabled. Returns the spec plus local validation errors and warnings.
```

### `flux_generate_keys`

- The name "flux_generate_keys" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Creates two fresh private keys (WIF): one for the Flux ID that will own apps, one for the address that pays. The response contains the secrets; store them in the MCP server environment as FLUX_ID_PRIVATE_KEY and FLUX_PAYMENT_PRIVATE_KEY, then restart the server. Nothing is stored or sent anywhere by this tool.
```

### `flux_validate_spec`

- The name "flux_validate_spec" says "validate": a word for reading.
- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs the local rule checks, then asks a FluxOS node to verify the specification exactly as it would at registration (image reachable, architecture, ports, name availability). Returns the node-formatted spec on success.
```

## Only reads (9)

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

### `flux_get_app`

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

Description, as the server wrote it:

```untrusted-server-text
Looks up any app on the network by name and returns its published specification, expiry, running instances, URLs and a reachability check: probes the shared domain (HTTP) and each instance port (TCP and HTTP) and explains what a 503 means, including when it is expected for non-web apps.
```

### `flux_get_app_logs`

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

Description, as the server wrote it:

```untrusted-server-text
Fetches the last N log lines of an app from one of the nodes running it. Requires the owner key. The component is picked automatically when the app has one (private apps are decrypted with the owner key); otherwise the available names are listed.
```

### `flux_get_app_stats`

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

Description, as the server wrote it:

```untrusted-server-text
CPU, memory and network stats of the containers of an app on one node. Requires the owner key.
```

### `flux_get_identity`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the Flux ID (app owner address), the payment address and its spendable FLUX balance with its USD value. Explains what to configure if keys are missing. Never returns private keys.
```

### `flux_get_network_info`

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

Description, as the server wrote it:

```untrusted-server-text
Node counts by tier, current block height, FLUX/USD rate and the deployment payment address.
```

### `flux_get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the current USD rate card, the live FLUX/USD rate, the pay-in-FLUX discount and instant USD estimates for a few reference sizes. Use flux_quote_app for the exact price of a specific app.
```

### `flux_list_my_apps`

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

Description, as the server wrote it:

```untrusted-server-text
Lists every app registered by the owner (or a given Flux ID) with expiry and instance counts.
```

### `flux_quote_app`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the Flux Cloud price for registering the given specification, or for updating it if an app of that name already exists (the unused part of the current term is credited). Price is in USD with the FLUX amount at market rate.
```

### `flux_wait_for_app`

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

Description, as the server wrote it:

```untrusted-server-text
Polls the network for up to timeoutSeconds (default 45 to fit hosts with a 60 s tool timeout, max 600). Returns payment confirmations, whether the spec was accepted, and the running instances with URLs. Safe to call repeatedly until done=true.
```
