Work with Linear issues through 11 common commands: read your profile, teams, members, projects, issues, labels and workflow states; create or update an issue and add a comment. Lists are one explicit page with cursors and optional filters. Only fixed GraphQL operations are supported, with typed variables and your personal API key’s permissions. This subset does not expose arbitrary queries, attachments, webhooks or every Linear API feature.

Connect and use
Open the integration's connection form to check the available credential source. The source has not been resolved for this documentation export. The instructions below apply when using your own provider account.
Get your provider credentials
Follow these steps for Linear, then enter the issued values in the connection form below.
- In Linear, open Settings → Account → Security & access → Personal API keys and create a key if your workspace role permits it. Restrict teams and permissions where supported. Paste the key into this connection’s Linear personal API key field, choose commands and save. Use resource UUIDs from list commands and explicit pagination cursors. Issue and comment mutations change workspace data. Create a separate Tooluse.net API key for your client; never place your Linear key in the MCP URL.
Where to enter credentials
In the integration page, sign in, choose your workspace and open Connect. If a Credentials choice is shown, select Use my credentials. Fill the following connection fields and save. Provider credentials belong in this form, never in an MCP configuration or tool input.
| Connection field | Requirement |
|---|---|
| Linear personal API key | Required |
Open API keys and create a Tooluse.net key for the enabled commands.
Set TOOLUSE_API_KEY in your client and use the shared MCP configuration.
Configure Claude Code, Codex or Cursor once
Permissions and results
If you have more than one workspace, check the selected workspace in the connection or API-key dialog before saving. Roles, enabled commands, expiry and revocation use Tooluse.net's existing permissions. Disabling a connection or revoking a key immediately prevents new calls.
Send one Claude tool_use block per request. Keep the same Idempotency-Key when retrying the same request; use a new key for a new call. The response includes the shared Tooluse.net receipt and Claude tool_result. Check both HTTP status and the returned tool result before treating a call as successful.
Your connection's daily allowance and key permissions also apply. Adding a connection does not make a provider request.
Calls return the shared execution receipt and a Claude tool_result. Provider output varies by operation; consult the provider documentation for its response fields. Unconfirmed calls should be checked before retrying.
Call from your client
Use the shared MCP configuration. Refresh your client's tool list after saving the connection or changing key permissions, then call the returned tool name with the example input below.
Configure Claude Code, Codex or Cursor once
Discover your enabled tools
List permitted tools in Claude format. Read every page using page and size (maximum 100) until all results have been received. Use the returned name, not a catalog capability identifier, in the tool_use block.
curl 'https://api.tooluse.net/v1/tools' \
-H "Authorization: Bearer $TOOLUSE_API_KEY"
Find this command in the tool list permitted by your key. Replace svc_FROM_YOUR_TOOL_LIST with its returned name. Use a new Idempotency-Key for each new call and retain it when retrying that same call.
HTTP call
curl 'https://api.tooluse.net/v1/tool-calls' \
-H "Authorization: Bearer $TOOLUSE_API_KEY" \
-H 'Content-Type: application/json' \
-H 'Idempotency-Key: replace-with-a-new-call-id' \
--data '{
"type": "tool_use",
"id": "toolu_example",
"name": "svc_FROM_YOUR_TOOL_LIST",
"input": {}
}'
Send one Claude tool_use block per request. Keep the same Idempotency-Key when retrying the same request; use a new key for a new call. The response includes the shared Tooluse.net receipt and Claude tool_result. Check both HTTP status and the returned tool result before treating a call as successful.

Refresh your client's tool list, use the returned tool name, and check the execution result and usage. Provider charges and permissions still apply. Never test a write against production data without reviewing it.
