streamlinear

streamlinear

A lightweight Linear MCP for Claude Code. One tool, seven actions.

Why?

The standard Linear MCP uses ~17,000 tokens for tool definitions.

streamlinear uses ~500 tokens.

Design Philosophy

Instead of 23 separate tools, streamlinear has one tool with action dispatch:

{"action": "search"}
{"action": "get", "id": "ABC-123"}
{"action": "update", "id": "ABC-123", "state": "Done"}
{"action": "comment", "id": "ABC-123", "body": "Fixed!"}
{"action": "create", "title": "New bug", "team": "ENG"}
{"action": "graphql", "graphql": "query { viewer { name } }"}
{"action": "help"}

Actions

Action	Purpose
search	Find issues (smart defaults: your active issues)
get	Issue details by ABC-123, URL, or UUID
update	Change state, priority, assignee
comment	Add comment to issue
create	Create new issue
graphql	Raw GraphQL for anything else
help	Full documentation

Installation

Single Workspace

Add to your .mcp.json:

{
  "mcpServers": {
    "linear": {
      "command": "npx",
      "args": ["-y", "@primeradianthq/[email protected]"],
      "env": {
        "LINEAR_API_TOKEN": "lin_api_xxxxx"
      }
    }
  }
}

Multiple Workspaces

To use streamlinear with multiple Linear workspaces, create separate MCP entries and map each secret to LINEAR_API_TOKEN:

{
  "mcpServers": {
    "linear-personal": {
      "command": "npx",
      "args": ["-y", "@primeradianthq/[email protected]"],
      "env": {
        "LINEAR_API_TOKEN": "${LINEAR_PERSONAL_TOKEN}"
      },
      "envFrom": ["LINEAR_PERSONAL_TOKEN"]
    },
    "linear-work": {
      "command": "npx",
      "args": ["-y", "@primeradianthq/[email protected]"],
      "env": {
        "LINEAR_API_TOKEN": "${LINEAR_WORK_TOKEN}"
      },
      "envFrom": ["LINEAR_WORK_TOKEN"]
    }
  }
}

Installed Package

When installed as a dependency, the package provides two binaries:

npm install @primeradianthq/[email protected]
npx streamlinear-cli help
npx streamlinear

The MCP server requires LINEAR_API_TOKEN at runtime. Consumers such as Scribble may expose their own operator-facing variable and map it to LINEAR_API_TOKEN before starting streamlinear.

Smart Defaults

• Teams and workflow states shown in tool description (fetched at startup)
• search with no params → your assigned issues, not completed/canceled
• IDs accept ABC-123, Linear URLs, or UUIDs
• State names are fuzzy matched ("done" → "Done", "in prog" → "In Progress")
• assignee: "me" uses the authenticated user
• Error messages show valid options when things fail

The GraphQL Escape Valve

For anything not covered by the main actions, use raw GraphQL:

{
  "action": "graphql",
  "graphql": "query { projects { nodes { id name } } }"
}

Use {"action": "help"} for common GraphQL patterns.
