Linear MCP

Operate Linear MCP through your OOMOL-connected account. This skill calls the linear_mcp connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

Assume the user has already installed the oo CLI, signed in, and connected Linear MCP. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

oo connector schema "linear_mcp" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

oo connector run "linear_mcp" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

Available actions

• create_comment — Comment on a Linear issue through Linear's MCP save_comment tool, optionally as a reply to another comment. Needs the write scope on the grant. [write]
• create_issue — Create a Linear issue through Linear's MCP save_issue tool. Needs the write scope on the grant; an id in the input is dropped so this never updates an existing issue. [write]
• get_issue — Get one Linear issue with its full description through Linear's MCP get_issue tool.
• get_self — Get the signed-in Linear user through Linear's MCP get_user tool.
• list_comments — List the comments on one Linear issue through Linear's MCP list_comments tool.
• list_issue_labels — List issue labels through Linear's MCP list_issue_labels tool, for the workspace or one team.
• list_issue_statuses — List one team's workflow states through Linear's MCP list_issue_statuses tool: the names the issue tools take as state.
• list_issues — List Linear issues through Linear's MCP list_issues tool with optional updated-since, ordering, limit, and cursor pagination. Descriptions may be clipped; call get_issue for the full text.
• list_projects — List Linear projects through Linear's MCP list_projects tool, optionally for one team, with cursor pagination.
• list_teams — List the teams of the connected Linear workspace through Linear's MCP list_teams tool: the keys and IDs the issue tools take as team.
• update_issue — Update a Linear issue through Linear's MCP save_issue tool with its id: the title, description, team, assignee, state, priority, labels, project, due date, parent or estimate. Needs the write scope on the grant. [write]

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change Linear MCP state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  

• Not signed in / authentication error — sign in to your OOMOL account once:

  oo auth login
  

• scope_missing / credential_expired / app_not_ready / app_not_found — Linear MCP is not connected, or the connection expired or lacks a scope. Connect once (auth type: OAuth2) at:

  https://console.oomol.com/connections/linear_mcp
  

• OOMOL_INSUFFICIENT_CREDIT — OOMOL billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.

• HTTP 402 without OOMOL_INSUFFICIENT_CREDIT — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.
