This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to next, this PR will be updated. # Releases ## @composio/core@0.17.0 ### Minor Changes -760f8d0: Allow OpenAI and Anthropic provider tool-call helpers to execute through a supplied Tool Router session. Session meta-tools now retain their session context while provider argument normalization remains intact; existing user-ID calls continue to use direct execution. Anthropic helper failures now preserve their error text in `{ error }` results without changing successful payloads. Custom provider subclasses overriding `executeToolCall` or `handleToolCalls` may require updates because these methods now accept session targets. ### Patch Changes -6ba9179: Validate the URLs that come from API responses before fetching them. Tool-execution downloads (`s3Url`), S3 presigned uploads (`new_presigned_url`), Tool Router session file downloads (`RemoteFile.buffer()` / `blob()` / `text()` / `save()`) and session file uploads (`upload_url`) now go through the same SSRF guard that already covered user-supplied URLs, so a response naming a private, loopback, or link-local address is refused instead of fetched. Redirect hops are re-validated. Edge runtimes keep their current behavior: session file transfers are not blocked there, since a Worker cannot resolve DNS to check and its `fetch` does not originate inside the caller's network. ## @composio/anthropic@0.11.0 ### Minor Changes -760f8d0: Allow OpenAI and Anthropic provider tool-call helpers to execute through a supplied Tool Router session. Session meta-tools now retain their session context while provider argument normalization remains intact; existing user-ID calls continue to use direct execution.

Composio TypeScript workspace
This directory contains the TypeScript half of the Composio SDK monorepo: the core SDK, provider adapters, the CLI, examples, and end-to-end tests. For an overview of Composio itself, start at the root README and docs.composio.dev.
If you just want to use the SDK:
npm install @composio/core
import { Composio } from '@composio/core';
const composio = new Composio({ apiKey: process.env.COMPOSIO_API_KEY });
const session = await composio.create('user_123');
const tools = await session.tools();
See the @composio/core README and the quickstart for the full flow, including provider setup for your agent framework.
Packages
Published packages:
| Package | Description |
|---|---|
@composio/core |
The Composio SDK. Ships its TypeScript source and SDK docs so installed copies are inspectable by coding agents. |
@composio/slim |
Same API as @composio/core without the packaged source and docs; smaller install. |
composio CLI |
Standalone CLI binary: search, execute, and script tools from your shell. |
@composio/* providers |
Adapters that format Composio tools for agent frameworks (OpenAI, Anthropic, Vercel AI SDK, LangChain, and more). See the provider table. |
@composio/experimental |
Experimental integrations, currently the Pi provider. |
@composio/json-schema-to-zod |
JSON Schema to Zod conversion. |
Internal (unpublished) packages: cli-keyring and cli-local-tools support the CLI; ts-builders generates TypeScript source.

Development
Commands run from the repository root. Install the pinned toolchain first:
mise install
pnpm install
Build and verify:
pnpm build:packages # build all TS packages
pnpm typecheck # typecheck all TS packages
pnpm lint:packages # oxlint over ts/packages
pnpm test # package unit tests plus example validation
Runtime E2E suites (require credentials):
pnpm test:e2e:node
pnpm test:e2e:deno
pnpm test:e2e:cloudflare
pnpm test:e2e:cli
Scaffolding:
pnpm create:provider <name> [--agentic] # new provider package
pnpm create:example <name> # new example under ts/examples
