update_strategyReplace the complete Python package and rules of an existing strategy using its exact current saved revision.No findings
Why it is in this group
- The name "update_strategy" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Replace the complete Python package and rules of an existing strategy using its exact current saved revision. The submitted package replaces all existing files. Supports all Premiss markets and timeframes. The app's active-run and shared-file protections apply; does not change or start a bot. Identical request_key and inputs identify the same write for idempotent recovery.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: true
- openWorldHint: false
- title: Edit a strategy

Changes things 3Creates or changes something that can be changed back.Claude Code: ask

create_strategySave a new private strategy using custom Python files and complete rules text, on any Premiss-supported market and timeframe.No findings
Why it is in this group
- The name "create_strategy" says "create": a word for a change.
Description, as the server wrote it
Save a new private strategy using custom Python files and complete rules text, on any Premiss-supported market and timeframe. Accepts either files (strategy.py plus helper modules) and rules, or a convenience template. Uses the same package format as the app. Returns code and revision; saving does not run a backtest.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
- title: Save a strategy
save_research_noteSave a NEW private note in the connected workspace, with optional exact owned strategy/run evidence references.No findings
Why it is in this group
- The name "save_research_note" says "save": a word for a change.
Description, as the server wrote it
Save a NEW private note in the connected workspace, with optional exact owned strategy/run evidence references. The note is user-authored content. Does not publish or send it anywhere.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
- title: Save a research note
start_backtestQueue a backtest of any saved strategy in the connected workspace and a matched buy-and-hold baseline.No findings
Why it is in this group
- The name "start_backtest" says "start": a word for a change.
Description, as the server wrote it
Queue a backtest of any saved strategy in the connected workspace and a matched buy-and-hold baseline. Accepts custom code and existing app strategies. Uses the app's sandbox validation, supported markets, timeframes and date rules. Requires the exact saved revision. Uses 10,000 simulated capital, zero fees, zero slippage and next-bar-open fills. Read the report assumptions for historical runs. No plugin-only daily test or history caps. Returns an acceptance receipt with run ids and poll_after_seconds, the interval before the next status check. Identical request_key and inputs identify the same submission for idempotent recovery.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
- title: Start a historical backtest

Only reads 9Looks things up and changes nothing.Claude Code: allow

get_capabilitiesRead this connection's available tools and supported research coverage.No findings
Why it is in this group
- The name "get_capabilities" says "get": a word for reading.
Description, as the server wrote it
Read this connection's available tools and supported research coverage. Does not read account data, save research, or run a simulation.
Annotations the server declares
- title: Premiss capabilities
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
get_profileRead the stable identity and workspace selected for this connection.No findings
Why it is in this group
- The name "get_profile" says "get": a word for reading.
Description, as the server wrote it
Read the stable identity and workspace selected for this connection. Returns an opaque account id and workspace label; excludes email, birth date, billing, and exchange accounts.

- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
- title: Premiss connected workspace
get_run_dataRead the immutable tested Python package, or page through all recorded trades or equity points for an owned run.No findings
Why it is in this group
- The name "get_run_data" says "get": a word for reading.
Description, as the server wrote it
Read the immutable tested Python package, or page through all recorded trades or equity points for an owned run. next_cursor identifies the next page; page size is not a history cap. Paper data requires separate paper:read permission. Saved code is user-authored content.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
- title: Read backtest code, trades or equity
get_run_reportRead the status and bounded performance report for one run in the connected workspace.No findings
Why it is in this group

Description, as the server wrote it
Read the status and bounded performance report for one run in the connected workspace. Returns the tested market, interval, revision, and recorded rules when verifiable. Historical plugin runs include the paired buy-and-hold baseline when completed. Paper reads require paper:read and do not start, stop, qualify, or modify a bot. Legacy runs without supported assumptions are labeled. Does not return raw market feeds.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as premiss. Review it before you use it.

Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
