ParrotScribe MCP Server (Deprecated) & Lex Copilot

[!WARNING] This MCP server is deprecated. It will continue to work for users who stay on Parrot Scribe versions before 0.4.0, but it will not work once you upgrade to 0.4.0 or newer. Use the integrated MCP server built into Parrot Scribe instead.

An MCP (Model Context Protocol) server that enables AI agents to interact with the ParrotScribe transcription service on macOS.

Meet Lex: Your Tactical Meeting Copilot

If you are using Opencode, I recommend that you use the pre-configured agent called Lex. Lex transforms passive transcription into an active research and navigation tool.

• Real-time Context: Ask "What's that?" or "What did they just say?" to get instant explanations.
• Zero-Latency Knowledge: Proactively loads domain-specific skills based on transcript keywords.
• Tactical Summaries: Generates structured meeting notes, identifying key facts and action items.
• Persona-Ready: Tailor Lex to any role (Journalist, Researcher, Engineer) via private directives.

Installing Lex

1. Ensure you are on Parrot Scribe < 0.4.0 and this MCP server is configured in your environment.
2. Copy agent/lex.md from this repository into your local .opencode/agent/ directory.

What It Does

ParrotScribe captures real-time audio from your microphone and system audio, transcribes it using Whisper, and this MCP server exposes that transcription data to AI agents. This enables workflows like:

• Meeting Monitor: AI monitors a live call and surfaces relevant information
• Action Item Tracker: AI detects commitments and prepares follow-up actions
• Real-time Researcher: AI looks up technical terms mentioned in conversation
• Session Summarizer: AI generates structured summaries after calls

Prerequisites

• macOS with ParrotScribe installed
• Node.js 18 or higher
• The pscribe CLI must be available in your PATH (it will be if ParrotScribe is installed correctly)
• Parrot Scribe version < 0.4.0 (once 0.4.0 is released, this package is unsupported)

Legacy Installation (Parrot Scribe < 0.4.0 only)

If you are using Parrot Scribe 0.4.0 (or newer), do not install this package. Use the app's integrated MCP server.

Option 1: NPX (Recommended)

No installation needed. Configure your AI agent to run:

npx @johanthoren/parrotscribe-mcp-server

Option 2: Global Install

npm install -g @johanthoren/parrotscribe-mcp-server

Then run with:

parrotscribe-mcp-server

Option 3: From Source

git clone https://github.com/johanthoren/parrotscribe-mcp.git
cd parrotscribe-mcp
npm install
npm run build
node dist/index.js

Configuration

Opencode

Add to your ~/.config/opencode/opencode.jsonc:

{
  "mcp": {
    "parrotscribe": {
      "type": "local",
      "command": ["npx", "@johanthoren/parrotscribe-mcp-server"]
    }
  }
}

Claude Code

Add to your project's .mcp.json or global MCP config:

{
  "mcpServers": {
    "parrotscribe": {
      "command": "npx",
      "args": ["@johanthoren/parrotscribe-mcp-server"]
    }
  }
}

Claude Desktop

Add to your claude_desktop_config.json (typically at ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "parrotscribe": {
      "command": "npx",
      "args": ["@johanthoren/parrotscribe-mcp-server"]
    }
  }
}

Environment Variables (Optional)

Variable	Description	Default
PSCRIBE_PATH	Path to the pscribe executable. Only needed if pscribe is not in your PATH (edge case).	pscribe

Available Tools

Tool	Description
pscribe_start	Start real-time audio transcription
pscribe_stop	Stop/pause the current transcription
pscribe_status	Get service status, session ID, duration
pscribe_tail	Get recent transcript entries with filtering
pscribe_cat	Display complete sessions with time-based filtering
pscribe_grep	Search for patterns across transcript sessions
pscribe_sessions	List past transcription sessions
pscribe_new	Force start a new session

pscribe_tail Parameters

Parameter	Type	Description
n	number	Number of entries to return (default: 10)
since_line	number	Start from line N (for polling)
status	string	Filter: all, confirmed, unconfirmed, translated, speech
session_id	string	Read from a specific session

pscribe_cat Parameters

Parameter	Type	Description
session_ids	string[]	Session IDs to display (from pscribe_sessions)
since	string	Show sessions starting after this ISO8601 timestamp
until	string	Show sessions starting before this ISO8601 timestamp
last	number	Show last N sessions
status	string	Filter: all, confirmed, unconfirmed, speech

Use pscribe_cat for historical queries like "summarize yesterday's standup" - the AI converts natural language time references to ISO8601.

pscribe_grep Parameters

Parameter	Type	Description
pattern	string	The pattern to search for (regex supported) - required
since	string	Only search sessions starting after this ISO8601 timestamp
until	string	Only search sessions starting before this ISO8601 timestamp
status	string	Filter: all, confirmed, unconfirmed, speech
ignore_case	boolean	Case-insensitive search
count	boolean	Show match count per session instead of matches
after_context	number	Show N lines after each match (-A)
before_context	number	Show N lines before each match (-B)
context	number	Show N lines before and after each match (-C)

Use pscribe_grep for queries like "did anyone mention deployment last week?" or "find all references to the API".

Output Format: TOON

The server returns transcript data in TOON format, a token-efficient format designed for LLM consumption:

transcript{timestamp,source,status,segment,confidence,duration,language,text}:
  2024-01-15T14:30:00+01:00,M,C,1,0.95,2.5,en,Hello world
  2024-01-15T14:30:05+01:00,S,C,2,0.92,3.1,sv,Hej dar

Fields

Field	Description
timestamp	ISO8601 with timezone
source	M (microphone), S (system audio), E (events)
status	C (confirmed), U (unconfirmed), T (translated), N (no_speech)
segment	Incrementing segment number
confidence	Whisper confidence score (0.0-1.0)
duration	Segment duration in seconds
language	ISO 639-1 code (e.g., en, sv, de)
text	Transcribed content

Polling Strategy

For real-time monitoring, agents should:

1. Call pscribe_status to ensure a session is active
2. Call pscribe_tail with n: 10 to get initial context
3. Note the last_line number from the response metadata
4. Periodically call pscribe_tail with since_line: last_line + 1
5. Use status: "confirmed" to focus on finalized transcriptions

Example Prompts

See the examples/ directory for ready-to-use prompts:

• standup.md: Daily standup meeting assistant
• retro.md: Sprint retrospective facilitator
• code-review.md: Code review meeting tracker
• pair-programming.md: Pair programming session monitor
• adr.md: Architecture Decision Record generator

Security & Privacy

• Local-Only: Data flows exclusively from the local pscribe CLI to the local AI agent via stdio
• Zero-Cloud: No analytics, no telemetry, no intermediate servers
• User Control: You decide when transcription is active and which AI agent receives the data
