First indexed and scored.

## MCP tools (6)

### `open_stage` (~86 tokens)

Open the live Agent Theatre stage for a repository folder: the repo becomes a stage and the running Claude Code session animates on it. Returns the URL to open. Reuses a stage that is already running for that folder.

Input parameters:

- `cwd` (string): Absolute path of the repository folder
- `set` (string): Stage set id, e.g. island, orbit, lanterns

### `list_sessions` (~56 tokens)

List past Claude Code sessions for a repository folder (newest first) that Agent Theatre can replay. Returns ids, titles and times only.

Input parameters:

- `cwd` (string): Absolute path of the repository folder
- `limit` (integer)

### `replay_session` (~80 tokens)

Open a replay of a past Claude Code session on the stage. Omit session_id for the newest. Returns the URL.

Input parameters:

- `cwd` (string): Absolute path of the repository folder
- `session_id` (string): A session id from list_sessions
- `set` (string): Stage set id, e.g. island, orbit, lanterns

### `stage_status` (~55 tokens)

What the live stage for a folder has seen so far: event and beat counts, the last few event kinds, and whether hooks are installed. Never returns file contents.

Input parameters:

- `cwd` (string): Absolute path of the repository folder

### `what_changed` (~115 tokens)

The change map: which files the agent read, edited, created or deleted (in the live stage for a folder, else the newest session), with line counts, files changed during the session but not by the agent, and a Markdown version for a pull request. Paths and counts only; never file contents.

Input parameters:

- `cwd` (string): Absolute path of the repository folder
- `markdown` (boolean): Return Markdown for a pull request instead of a plain list
- `session_id` (string): A session id from list_sessions

### `install_hooks` (~38 tokens)

Install the Agent Theatre hooks into ~/.claude/settings.json (non-destructive, keeps a backup). Not needed when the Claude Code plugin is installed.

## Common questions

### What is the io.github.shreyassaw5394/agent-theatre MCP server?

io.github.shreyassaw5394/agent-theatre is an MCP server listed in the public MCP registry as io.github.shreyassaw5394/agent-theatre. Watch your coding agent work as a film: opens and replays the Agent Theatre stage for a repo. This page covers its npm package (agent-theatre).

### Is the io.github.shreyassaw5394/agent-theatre MCP server safe to use?

io.github.shreyassaw5394/agent-theatre scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.shreyassaw5394/agent-theatre MCP server expose?

io.github.shreyassaw5394/agent-theatre exposes 6 tools: open_stage, list_sessions, replay_session, stage_status, what_changed, install_hooks. Their descriptions and schemas cost roughly 430 tokens of context every time the server is loaded.

### Is the io.github.shreyassaw5394/agent-theatre MCP server still maintained?

io.github.shreyassaw5394/agent-theatre is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.shreyassaw5394/agent-theatre MCP server under?

io.github.shreyassaw5394/agent-theatre declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the io.github.shreyassaw5394/agent-theatre MCP server?

VerifyMCP ran 16 checks on io.github.shreyassaw5394/agent-theatre, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
