This PR:
- reverts https://github.com/ComposioHQ/composio/pull/3780
- restores the TypeScript `composio.create()` and `composio.use()`
session aliases, with their runtime and type-test coverage
- restores the prior deprecation state for
`BaseProvider.wrapMcpServerResponse`
- removes the pre-v1 breaking-change changeset so the release PR no
longer advertises this removal
The v1 API-freeze change should be recreated later as a draft PR and
kept out of the merge queue until v1 is ready.
## What and why
This makes the intended v1 API cleanup real rather than postponing it to
v2:
- Remove the TypeScript root aliases `composio.create(...)` and
`composio.use(...)`. Session creation and reuse now live only at
`composio.sessions.create(...)` and `composio.sessions.use(...)`. This
is a deliberate breaking change, reflected by a major changeset.
- Retain `BaseProvider.wrapMcpServerResponse` as the stable v1 provider
SPI. Its earlier deprecation pointed to a method that was never
introduced.
The scope is intentionally narrow: it does **not** remove unrelated
deprecated APIs, and Python keeps its supported `Composio.create/use`
API. The TypeScript docs, examples, providers, runtime fixtures,
generated SDK reference, and API-reference indexes now use the
namespaced TypeScript API. Historical changelog examples are left as
history.
## Verification
- `pnpm typecheck`
- `pnpm --filter @composio/core test -- --run test/core/session.test.ts`
(42 files, 1,018 tests)
- `pnpm exec eslint ts/packages/core/src/composio.ts`
- `pnpm --filter @composio/core generate:docs`
- `cd docs && bun run generate:api-index`
- `cd docs && bun run types:check`
- `git diff --check` and targeted scans for removed TypeScript aliases
I also attempted the affected Node and Cloudflare runtime E2E suites.
They cannot initialize in this checkout without `COMPOSIO_API_KEY` (and,
for Cloudflare, `COMPOSIO_BASE_URL` and `OPENAI_API_KEY`); they did not
report a product assertion failure.
## Summary
- Refresh the checked-in v3.1 and v3 OpenAPI snapshots from the live
backend specs using `bun run scripts/fetch-openapi.mjs`.
- Regenerate API reference index pages with `bun run
generate:api-index`.
- Surfaces `DELETE /api/v3.1/tool_router/session/{session_id}` in the
Tool Router API reference.
- Includes the other upstream generated spec changes from the same
auto-fetch, including generated API Keys and Organization Management
section indexes.
## Verification
- `bun run scripts/fetch-openapi.mjs`
- `bun run generate:api-index`
- `git diff --check`
- `bun run build`
## Notes before merge
- This is intentionally the full auto-generated OpenAPI refresh, not the
surgical two-file patch.
- The generated backend OpenAPI still contains some `internal` wording
in descriptions; left as-is to preserve the auto-generated output.
- Confirm the newly generated API Keys / Organization Management
sections are intended to publish with this refresh.

Integration branch for the next docs release: a **sessions-first
documentation rewrite** — new and rewritten guides, example pages,
interactive components, and docs tooling — plus the supporting SDK
changes that the new docs describe.
The bulk of this PR is docs (~24k lines across ~150 commits); the SDK
changes (~5k lines) back the new guides.
## Documentation (the bulk)
- **Sessions-first restructure** — reorganized navigation and section
structure (incl. the "Sandbox (prev workbench)" section), with
v3-reorganization redirects so old URLs keep resolving.
- **Rewritten core guides** — quickstart, configuring sessions, triggers
(creating + subscribing to events), proxy-execute, toolkits
enable/disable, and common FAQ, rewritten in the house voice.
- **New example pages** — local-sandbox PR reviewer, daily standup bot,
and slack bot, with runnable build-ups.
- **New interactive components & diagrams** — triggers flow animation,
manage-connections visual, connection-refresh visual, and the
terminal-kit components.
- **Docs tooling** — a docs-graph link-graph connectivity checker,
search reprioritization (deprioritize legacy pages), and SDK-reference
regeneration.
## Supporting SDK changes
**`@composio/core` → 0.13.0 (minor)**
- `composio.sessions.create()` as the first-class sessions API
(`composio.create()` kept as an alias).
- **MCP is opt-in:** default `create()` / `use()` return native-tool
sessions (`SessionWithoutMcp`); pass `{ mcp: true }` to surface
`session.mcp`. _Migration: read `session.mcp` only after creating with
`{ mcp: true }`._
- `session.sandbox` is the canonical resolved config;
`session.workbench` kept as a deprecated alias. `sandbox` is the
preferred session-config key (`workbench` still accepted).
- `connectedAccounts.updateAcl()` graduated from experimental (alias
kept).
- `triggers.parse()` (parse + optionally verify an incoming webhook) and
`triggers.setWebhookSubscription()`.
**`@composio/experimental` → minor** — local-workbench helpers moved
onto the `@composio/experimental/workbench` subpath (out of
`@composio/core/experimental`), keeping the ~14 KB embedded Python
helper out of core. Plus the experimental Pi provider.
**`@composio/slim` → minor.**
**Python → 0.17.0** — mirrors the TS surface: `composio.sessions` mount
(`tool_router` deprecated), `triggers.parse()` /
`set_webhook_subscription()`, the `sandbox` config key, and
`connected_accounts.update_acl()`.
## Review response (#3664)
Addressed the `@composio/core` review:
- **Security:** `triggers.parse()` no longer fails open — a
present-but-empty `verifySecret` (e.g. unset `COMPOSIO_WEBHOOK_SECRET`)
now throws instead of silently skipping verification; omitting it stays
an explicit opt-out (both SDKs).
- Removed snake_case leakage from `transformWebhookSubscription` (+ the
index signature that allowed it).
- **Removed** the TS-only `connectedAccounts.link()` toolkit
auto-resolve (shipped with cancellability / orphaned-auth-config bugs
and was effectively undocumented; to be reintroduced properly later).
- Unified Python error types on `ValidationError`; added `mcp=True`
Python tests; fixed runtime-portability + error-type test assertions.
- Polished deprecation messages; fixed the backwards `/experimental`
`@deprecated` note and the `SessionWithMcp` JSDoc.
## Testing
- **TS:** `@composio/core` + `@composio/experimental` typecheck pass;
vitest green for the touched suites.
- **Python:** `test_tool_router.py` + `test_triggers.py` pass (161
tests).
