Users and sessions

A user ID is an identifier from your system (database ID, UUID, or any unique string) that scopes connected accounts and tool access to a specific user. User IDs can represent individuals, teams, or organizations. See User Management for patterns.

A session is an ephemeral configuration that combines:

Which user's connected accounts to use
Which toolkits are available
Which auth configs to use

Tool Router's meta-tools are the same for everyone. The session determines the context they operate within.

Creating a session

session = composio.create(user_id="user_123")

const const session: ToolRouterSession<unknown, unknown, OpenAIProvider>session = await const composio: Composio<OpenAIProvider>composio.Composio<OpenAIProvider>.create: (userId: string, routerConfig?: ToolRouterCreateSessionConfig) => Promise<ToolRouterSession<unknown, unknown, OpenAIProvider>>Creates a new tool router session for a user.
@paramuserId The user id to create the session for@paramconfig The config for the tool router session@returnsThe tool router session@example```typescript
import { Composio } from '@composio/core';

const composio = new Composio();
const userId = 'user_123';

const session = await composio.create(userId, {
 manageConnections: true,
});

console.log(session.sessionId);
console.log(session.url);
console.log(session.tools());
```create("user_123");

Enabling toolkits

Restrict the session to specific toolkits:

# Using array format
session = composio.create(
    user_id="user_123",
    toolkits=["github", "gmail", "slack"]
)

# Using object format with enable key
session = composio.create(
    user_id="user_123",
    toolkits={"enable": ["github", "gmail", "slack"]}
)

// Using array format
const const session: ToolRouterSession<unknown, unknown, OpenAIProvider>session = await const composio: Composio<OpenAIProvider>composio.Composio<OpenAIProvider>.create: (userId: string, routerConfig?: ToolRouterCreateSessionConfig) => Promise<ToolRouterSession<unknown, unknown, OpenAIProvider>>Creates a new tool router session for a user.
@paramuserId The user id to create the session for@paramconfig The config for the tool router session@returnsThe tool router session@example```typescript
import { Composio } from '@composio/core';

const composio = new Composio();
const userId = 'user_123';

const session = await composio.create(userId, {
 manageConnections: true,
});

console.log(session.sessionId);
console.log(session.url);
console.log(session.tools());
```create("user_123", {
  
toolkits?: string[] | {
    disable: string[];
} | {
    enable: string[];
} | undefinedtoolkits: ["github", "gmail", "slack"],
});

// Using object format with enable key
const const session2: ToolRouterSession<unknown, unknown, OpenAIProvider>session2 = await const composio: Composio<OpenAIProvider>composio.Composio<OpenAIProvider>.create: (userId: string, routerConfig?: ToolRouterCreateSessionConfig) => Promise<ToolRouterSession<unknown, unknown, OpenAIProvider>>Creates a new tool router session for a user.

import { Composio } from '@composio/core';

const composio = new Composio();
const userId = 'user_123';

const session = await composio.create(userId, {
 manageConnections: true,
});

console.log(session.sessionId);
console.log(session.url);
console.log(session.tools());
```create("user_123", {
  
toolkits?: string[] | {
    disable: string[];
} | {
    enable: string[];
} | undefinedtoolkits: { enable: string[]enable: ["github", "gmail", "slack"] },
});

Disabling toolkits

Keep all toolkits enabled except specific ones:

session = composio.create(
    user_id="user_123",
    toolkits={"disable": ["exa", "firecrawl"]}
)

const const session: ToolRouterSession<unknown, unknown, OpenAIProvider>session = await const composio: Composio<OpenAIProvider>composio.Composio<OpenAIProvider>.create: (userId: string, routerConfig?: ToolRouterCreateSessionConfig) => Promise<ToolRouterSession<unknown, unknown, OpenAIProvider>>Creates a new tool router session for a user.
@paramuserId The user id to create the session for@paramconfig The config for the tool router session@returnsThe tool router session@example```typescript
import { Composio } from '@composio/core';

const composio = new Composio();
const userId = 'user_123';

const session = await composio.create(userId, {
 manageConnections: true,
});

console.log(session.sessionId);
console.log(session.url);
console.log(session.tools());
```create("user_123", {
  
toolkits?: string[] | {
    disable: string[];
} | {
    enable: string[];
} | undefinedtoolkits: { disable: string[]disable: ["exa", "firecrawl"] },
});

Custom auth configs

Use your own OAuth credentials instead of Composio's defaults:

session = composio.create(
    user_id="user_123",
    auth_configs={
        "github": "ac_your_github_config",
        "slack": "ac_your_slack_config"
    }
)

const const session: ToolRouterSession<unknown, unknown, OpenAIProvider>session = await const composio: Composio<OpenAIProvider>composio.Composio<OpenAIProvider>.create: (userId: string, routerConfig?: ToolRouterCreateSessionConfig) => Promise<ToolRouterSession<unknown, unknown, OpenAIProvider>>Creates a new tool router session for a user.
@paramuserId The user id to create the session for@paramconfig The config for the tool router session@returnsThe tool router session@example```typescript
import { Composio } from '@composio/core';

const composio = new Composio();
const userId = 'user_123';

const session = await composio.create(userId, {
 manageConnections: true,
});

console.log(session.sessionId);
console.log(session.url);
console.log(session.tools());
```create("user_123", {
  authConfigs?: Record<string, string> | undefinedauthConfigs: {
    github: stringgithub: "ac_your_github_config",
    slack: stringslack: "ac_your_slack_config",
  },
});

See White-labeling authentication for branding, or Using custom auth configs for toolkits that require your own credentials.

Connected accounts

Connected accounts are stored in Composio and persist across sessions. When a user connects their GitHub account in one session, it remains available in future sessions. Sessions configure which connections to use, but don't own the connections themselves.

Account selection

If a user has multiple connected accounts for the same toolkit, you can specify which one to use:

session = composio.create(
    user_id="user_123",
    connected_accounts={
        "gmail": "ca_work_gmail",
        "github": "ca_personal_github"
    }
)

const const session: ToolRouterSession<unknown, unknown, OpenAIProvider>session = await const composio: Composio<OpenAIProvider>composio.Composio<OpenAIProvider>.create: (userId: string, routerConfig?: ToolRouterCreateSessionConfig) => Promise<ToolRouterSession<unknown, unknown, OpenAIProvider>>Creates a new tool router session for a user.
@paramuserId The user id to create the session for@paramconfig The config for the tool router session@returnsThe tool router session@example```typescript
import { Composio } from '@composio/core';

const composio = new Composio();
const userId = 'user_123';

const session = await composio.create(userId, {
 manageConnections: true,
});

console.log(session.sessionId);
console.log(session.url);
console.log(session.tools());
```create("user_123", {
  connectedAccounts?: Record<string, string> | undefinedconnectedAccounts: {
    gmail: stringgmail: "ca_work_gmail",
    github: stringgithub: "ca_personal_github",
  },
});

Precedence

When executing a tool, Tool Router selects the connected account in this order:

connectedAccounts override if provided in session config
authConfigs override - finds or creates connection on that config
Auth config previously created by Tool Router for this toolkit
Creates new auth config using Composio managed auth (tagged as Tool Router created)
Error if no Composio managed auth scheme exists for the toolkit

If a user has multiple connected accounts for a toolkit, the most recently connected one is used.

Session methods

mcp

Get the MCP server URL to use with any MCP-compatible client.

mcp_url = session.mcp.url

const { 
const mcp: {
    type: "http" | "sse";
    url: string;
    headers?: Record<string, string> | undefined;
}The MCP server config of the tool router session.
Contains the URL, type ('http' or 'sse'), and headers for authentication.mcp } = const session: ToolRouterSession<unknown, unknown, OpenAIProvider>session;
var console: ConsoleThe `console` module provides a simple debugging console that is similar to the
JavaScript console mechanism provided by web browsers.

The module exports two specific components:

* A `Console` class with methods such as `console.log()`, `console.error()` and `console.warn()` that can be used to write to any Node.js stream.
* A global `console` instance configured to write to [`process.stdout`](https://nodejs.org/docs/latest-v24.x/api/process.html#processstdout) and
[`process.stderr`](https://nodejs.org/docs/latest-v24.x/api/process.html#processstderr). The global `console` can be used without importing the `node:console` module.

_**Warning**_: The global console object's methods are neither consistently
synchronous like the browser APIs they resemble, nor are they consistently
asynchronous like all other Node.js streams. See the [`note on process I/O`](https://nodejs.org/docs/latest-v24.x/api/process.html#a-note-on-process-io) for
more information.

Example using the global `console`:

```js
console.log('hello world');
// Prints: hello world, to stdout
console.log('hello %s', 'world');
// Prints: hello world, to stdout
console.error(new Error('Whoops, something bad happened'));
// Prints error message and stack trace to stderr:
//   Error: Whoops, something bad happened
//     at [eval]:5:15
//     at Script.runInThisContext (node:vm:132:18)
//     at Object.runInThisContext (node:vm:309:38)
//     at node:internal/process/execution:77:19
//     at [eval]-wrapper:6:22
//     at evalScript (node:internal/process/execution:76:60)
//     at node:internal/main/eval_string:23:3

const name = 'Will Robinson';
console.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to stderr
```

Example using the `Console` class:

```js
const out = getStreamSomehow();
const err = getStreamSomehow();
const myConsole = new console.Console(out, err);

myConsole.log('hello world');
// Prints: hello world, to out
myConsole.log('hello %s', 'world');
// Prints: hello world, to out
myConsole.error(new Error('Whoops, something bad happened'));
// Prints: [Error: Whoops, something bad happened], to err

const name = 'Will Robinson';
myConsole.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to err
```
