Composio CLI

Default Workflow

1. Start with composio execute <slug> whenever the slug is known.
2. If several independent tool calls must happen at once, use composio execute -p/--parallel with repeated <slug> -d <json> groups.
3. If execute says the toolkit is not connected, run composio link <toolkit> and retry.
4. If the arguments are unclear, run composio execute <slug> --get-schema or --dry-run before guessing.
5. Reach for composio search "<task>" only when the slug is unknown. search accepts one or more queries, so batch related discovery work into a single command when useful.

execute - Run A Tool

Use execute when the tool slug is already known.

composio execute GITHUB_GET_THE_AUTHENTICATED_USER -d '{}'

Inspect required inputs without executing:

composio execute GITHUB_CREATE_AN_ISSUE --get-schema

Preview safely:

composio execute GITHUB_CREATE_AN_ISSUE --skip-connection-check --dry-run -d '{ owner: "acme", repo: "app", title: "Bug report", body: "Steps to reproduce..." }'

Pass data from a file or stdin:

composio execute GITHUB_CREATE_AN_ISSUE -d @issue.json
cat issue.json | composio execute GITHUB_CREATE_AN_ISSUE -d -

Upload a local file:

composio execute SLACK_UPLOAD_OR_CREATE_A_FILE_IN_SLACK \
  --file ./image.png \
  -d '{ channels: "C123" }'

Run independent tool calls in parallel:

composio execute --parallel \
  GMAIL_SEND_EMAIL -d '{ recipient_email: "a@b.com", subject: "Hi" }' \
  GITHUB_CREATE_AN_ISSUE -d '{ owner: "acme", repo: "app", title: "Bug" }'

Key flags:

• --get-schema: Inspect required arguments without executing the tool.

• --dry-run: Preview the request shape without performing the action.

• --file: Inject a local file path into a tool that exposes exactly one uploadable file argument.

• --parallel: Execute multiple independent tool calls in the same invocation.

• --account: Select which connected account to use by alias, word_id, or account id when multiple accounts exist for the same toolkit.

• --file only works when the tool exposes a single uploadable file input. Otherwise use explicit -d JSON.

search - Find The Slug

Use search only when the tool slug is not already known.

composio search "create a github issue"
composio search "send an email" --toolkits gmail
composio search "send an email" "create a github issue"
composio search "my emails" "my github issues" --toolkits gmail,github

• Batch related discovery work into one search invocation, then move back to execute once the correct slugs are known.

link - Connect An Account

Use link when execute reports that a toolkit is not connected, or when the user explicitly wants to authorize an account.

composio link gmail
composio link googlecalendar --no-browser

Key flags:

• --alias: Assign an alias to the connected account. Required when creating an additional account for the same toolkit.

• Retry the original execute command after linking succeeds.

proxy - Raw API Access

Use proxy when a toolkit supports a raw API operation that is easier than finding a dedicated tool slug.

composio proxy https://api.github.com/user --toolkit github --method GET </dev/null

run - Scripting, LLMs, and Programmatic Workflows

For programmatic calls, loops, output plumbing, or anything beyond a single tool call, prefer composio run.

composio run executes an inline ESM JavaScript/TypeScript snippet with authenticated execute(), search(), proxy(), and the experimental experimental_subAgent() helper pre-injected. No SDK setup required.

Chain multiple tools:

composio run '
  const me = await execute("GITHUB_GET_THE_AUTHENTICATED_USER");
  const emails = await execute("GMAIL_FETCH_EMAILS", { max_results: 1 });
  console.log({ login: me.data.login, fetchedEmails: !!emails.data });
'

Fan out with Promise.all:

composio run '
  const [me, emails] = await Promise.all([
    execute("GITHUB_GET_THE_AUTHENTICATED_USER"),
    execute("GMAIL_FETCH_EMAILS", { max_results: 5 }),
  ]);
  console.log({ login: me.data.login, emailCount: emails.data.messages?.length });
'

Feed tool output into an LLM and get structured JSON back:

composio run --logs-off '
  const emails = await execute("GMAIL_FETCH_EMAILS", { max_results: 5 });
  const brief = await experimental_subAgent(
    `Summarize these emails and count them.\n\n${emails.prompt()}`,
    { schema: z.object({ summary: z.string(), count: z.number() }) }
  );
  console.log(brief.structuredOutput);
'

• Use top-level execute --parallel instead when the user only needs a few independent tool calls and does not need script logic.

Auth

composio whoami   # check current session
composio login    # authenticate if whoami fails

Escalate Only When Needed

If the user is stuck on top-level commands or needs fallback inspection commands, load references/troubleshooting.md.

If the user explicitly asks about developer projects, auth configs, connected accounts, triggers, logs, orgs, or projects, load references/composio-dev.md. composio dev is not the default end-user path.
