# @modelcontextprotocol/client

## 2.0.0

### Patch Changes

- [#1343](https://github.com/modelcontextprotocol/typescript-sdk/pull/1343) [`4b5fdcb`](https://github.com/modelcontextprotocol/typescript-sdk/commit/4b5fdcba02c20f26d8b0f07acc87248288522842) Thanks [@christso](https://github.com/christso)! - Fix OAuth error handling for servers
returning errors with HTTP 200 status

Some OAuth servers (e.g., GitHub) return error responses with HTTP 200 status instead of 4xx. The SDK now checks for an `error` field in the JSON response before attempting to parse it as tokens, providing users with meaningful error messages.

- [#1386](https://github.com/modelcontextprotocol/typescript-sdk/pull/1386) [`00249ce`](https://github.com/modelcontextprotocol/typescript-sdk/commit/00249ce86dac558fb1089aea46d4d6d14e9a56c6) Thanks [@PederHP](https://github.com/PederHP)! - Respect capability negotiation in list
methods by returning empty lists when server lacks capability

The Client now returns empty lists instead of sending requests to servers that don't advertise the corresponding capability:
- `listPrompts()` returns `{ prompts: [] }` if server lacks prompts capability
- `listResources()` returns `{ resources: [] }` if server lacks resources capability
- `listResourceTemplates()` returns `{ resourceTemplates: [] }` if server lacks resources capability
- `listTools()` returns `{ tools: [] }` if server lacks tools capability

This respects the MCP spec requirement that "Both parties SHOULD respect capability negotiation" and avoids unnecessary server warnings and traffic. The existing `enforceStrictCapabilities` option continues to throw errors when set to `true`.

- [#1279](https://github.com/modelcontextprotocol/typescript-sdk/pull/1279) [`71ae3ac`](https://github.com/modelcontextprotocol/typescript-sdk/commit/71ae3acee0203a1023817e3bffcd172d0966d2ac) Thanks [@KKonstantinov](https://github.com/KKonstantinov)! - Initial 2.0.0-alpha.0

### Patch Changes

- [#1363](https://github.com/modelcontextprotocol/typescript-sdk/pull/1363) [`0a75810`](https://github.com/modelcontextprotocol/typescript-sdk/commit/0a75810b26e24bae6b9cfb41e12ac770aeaa1da4) Thanks [@DevJanderson](https://github.com/DevJanderson)! - Fix ReDoS vulnerability in

session isolation. Previously, sessionId was accepted but ignored on all TaskStore methods, allowing any session to enumerate, read, and mutate tasks created by other sessions. The store now persists sessionId at creation time and enforces ownership on all reads and writes.

# @modelcontextprotocol/client

## 2.0.0

### Patch Changes

- [#1343](https://github.com/modelcontextprotocol/typescript-sdk/pull/1343) [`4b5fdcb`](https://github.com/modelcontextprotocol/typescript-sdk/commit/4b5fdcba02c20f26d8b0f07acc87248288522842) Thanks [@christso](https://github.com/christso)! - Fix OAuth error handling for servers
returning errors with HTTP 200 status

Some OAuth servers (e.g., GitHub) return error responses with HTTP 200 status instead of 4xx. The SDK now checks for an `error` field in the JSON response before attempting to parse it as tokens, providing users with meaningful error messages.

- [#1386](https://github.com/modelcontextprotocol/typescript-sdk/pull/1386) [`00249ce`](https://github.com/modelcontextprotocol/typescript-sdk/commit/00249ce86dac558fb1089aea46d4d6d14e9a56c6) Thanks [@PederHP](https://github.com/PederHP)! - Respect capability negotiation in list
methods by returning empty lists when server lacks capability

The Client now returns empty lists instead of sending requests to servers that don't advertise the corresponding capability:
- `listPrompts()` returns `{ prompts: [] }` if server lacks prompts capability
- `listResources()` returns `{ resources: [] }` if server lacks resources capability
- `listResourceTemplates()` returns `{ resourceTemplates: [] }` if server lacks resources capability
- `listTools()` returns `{ tools: [] }` if server lacks tools capability

This respects the MCP spec requirement that "Both parties SHOULD respect capability negotiation" and avoids unnecessary server warnings and traffic. The existing `enforceStrictCapabilities` option continues to throw errors when set to `true`.

# @modelcontextprotocol/client

## 2.0.0

### Patch Changes

- [#1343](https://github.com/modelcontextprotocol/typescript-sdk/pull/1343) [`4b5fdcb`](https://github.com/modelcontextprotocol/typescript-sdk/commit/4b5fdcba02c20f26d8b0f07acc87248288522842) Thanks [@christso](https://github.com/christso)! - Fix OAuth error handling for servers

- [#1386](https://github.com/modelcontextprotocol/typescript-sdk/pull/1386) [`00249ce`](https://github.com/modelcontextprotocol/typescript-sdk/commit/00249ce86dac558fb1089aea46d4d6d14e9a56c6) Thanks [@PederHP](https://github.com/PederHP)! - Respect capability negotiation in list
methods by returning empty lists when server lacks capability

The Client now returns empty lists instead of sending requests to servers that don't advertise the corresponding capability:
- `listPrompts()` returns `{ prompts: [] }` if server lacks prompts capability
- `listResources()` returns `{ resources: [] }` if server lacks resources capability
- `listResourceTemplates()` returns `{ resourceTemplates: [] }` if server lacks resources capability
- `listTools()` returns `{ tools: [] }` if server lacks tools capability

This respects the MCP spec requirement that "Both parties SHOULD respect capability negotiation" and avoids unnecessary server warnings and traffic. The existing `enforceStrictCapabilities` option continues to throw errors when set to `true`.

# @modelcontextprotocol/client

## 2.0.0

### Patch Changes

- [#1343](https://github.com/modelcontextprotocol/typescript-sdk/pull/1343) [`4b5fdcb`](https://github.com/modelcontextprotocol/typescript-sdk/commit/4b5fdcba02c20f26d8b0f07acc87248288522842) Thanks [@christso](https://github.com/christso)! - Fix OAuth error handling for servers
returning errors with HTTP 200 status

Some OAuth servers (e.g., GitHub) return error responses with HTTP 200 status instead of 4xx. The SDK now checks for an `error` field in the JSON response before attempting to parse it as tokens, providing users with meaningful error messages.

- [#1386](https://github.com/modelcontextprotocol/typescript-sdk/pull/1386) [`00249ce`](https://github.com/modelcontextprotocol/typescript-sdk/commit/00249ce86dac558fb1089aea46d4d6d14e9a56c6) Thanks [@PederHP](https://github.com/PederHP)! - Respect capability negotiation in list
methods by returning empty lists when server lacks capability

The Client now returns empty lists instead of sending requests to servers that don't advertise the corresponding capability:
- `listPrompts()` returns `{ prompts: [] }` if server lacks prompts capability
- `listResources()` returns `{ resources: [] }` if server lacks resources capability
- `listResourceTemplates()` returns `{ resourceTemplates: [] }` if server lacks resources capability
- `listTools()` returns `{ tools: [] }` if server lacks tools capability

This respects the MCP spec requirement that "Both parties SHOULD respect capability negotiation" and avoids unnecessary server warnings and traffic. The existing `enforceStrictCapabilities` option continues to throw errors when set to `true`.

# @modelcontextprotocol/client

## 2.0.0

### Patch Changes

- [#1343](https://github.com/modelcontextprotocol/typescript-sdk/pull/1343) [`4b5fdcb`](https://github.com/modelcontextprotocol/typescript-sdk/commit/4b5fdcba02c20f26d8b0f07acc87248288522842) Thanks [@christso](https://github.com/christso)! - Fix OAuth error handling for servers
returning errors with HTTP 200 status

Some OAuth servers (e.g., GitHub) return error responses with HTTP 200 status instead of 4xx. The SDK now checks for an `error` field in the JSON response before attempting to parse it as tokens, providing users with meaningful error messages.

- [#1386](https://github.com/modelcontextprotocol/typescript-sdk/pull/1386) [`00249ce`](https://github.com/modelcontextprotocol/typescript-sdk/commit/00249ce86dac558fb1089aea46d4d6d14e9a56c6) Thanks [@PederHP](https://github.com/PederHP)! - Respect capability negotiation in list
methods by returning empty lists when server lacks capability

The Client now returns empty lists instead of sending requests to servers that don't advertise the corresponding capability:
- `listPrompts()` returns `{ prompts: [] }` if server lacks prompts capability
- `listResources()` returns `{ resources: [] }` if server lacks resources capability
- `listResourceTemplates()` returns `{ resourceTemplates: [] }` if server lacks resources capability
- `listTools()` returns `{ tools: [] }` if server lacks tools capability

This respects the MCP spec requirement that "Both parties SHOULD respect capability negotiation" and avoids unnecessary server warnings and traffic. The existing `enforceStrictCapabilities` option continues to throw errors when set to `true`.

- [#1279](https://github.com/modelcontextprotocol/typescript-sdk/pull/1279) [`71ae3ac`](https://github.com/modelcontextprotocol/typescript-sdk/commit/71ae3acee0203a1023817e3bffcd172d0966d2ac) Thanks [@KKonstantinov](https://github.com/KKonstantinov)! - Initial 2.0.0-alpha.0

session isolation. Previously, sessionId was accepted but ignored on all TaskStore methods, allowing any session to enumerate, read, and mutate tasks created by other sessions. The store now persists sessionId at creation time and enforces ownership on all reads and writes.

# @modelcontextprotocol/client

## 2.0.0

### Patch Changes

- [#1343](https://github.com/modelcontextprotocol/typescript-sdk/pull/1343) [`4b5fdcb`](https://github.com/modelcontextprotocol/typescript-sdk/commit/4b5fdcba02c20f26d8b0f07acc87248288522842) Thanks [@christso](https://github.com/christso)! - Fix OAuth error handling for servers
returning errors with HTTP 200 status

Some OAuth servers (e.g., GitHub) return error responses with HTTP 200 status instead of 4xx. The SDK now checks for an `error` field in the JSON response before attempting to parse it as tokens, providing users with meaningful error messages.

- [#1386](https://github.com/modelcontextprotocol/typescript-sdk/pull/1386) [`00249ce`](https://github.com/modelcontextprotocol/typescript-sdk/commit/00249ce86dac558fb1089aea46d4d6d14e9a56c6) Thanks [@PederHP](https://github.com/PederHP)! - Respect capability negotiation in list
methods by returning empty lists when server lacks capability

The Client now returns empty lists instead of sending requests to servers that don't advertise the corresponding capability:
- `listPrompts()` returns `{ prompts: [] }` if server lacks prompts capability
- `listResources()` returns `{ resources: [] }` if server lacks resources capability
- `listResourceTemplates()` returns `{ resourceTemplates: [] }` if server lacks resources capability
- `listTools()` returns `{ tools: [] }` if server lacks tools capability

This respects the MCP spec requirement that "Both parties SHOULD respect capability negotiation" and avoids unnecessary server warnings and traffic. The existing `enforceStrictCapabilities` option continues to throw errors when set to `true`.

### Patch Changes

- [#1363](https://github.com/modelcontextprotocol/typescript-sdk/pull/1363) [`0a75810`](https://github.com/modelcontextprotocol/typescript-sdk/commit/0a75810b26e24bae6b9cfb41e12ac770aeaa1da4) Thanks [@DevJanderson](https://github.com/DevJanderson)! - Fix ReDoS vulnerability in
UriTemplate regex patterns (CVE-2026-0621)

session isolation. Previously, sessionId was accepted but ignored on all TaskStore methods, allowing any session to enumerate, read, and mutate tasks created by other sessions. The store now persists sessionId at creation time and enforces ownership on all reads and writes.

global Response object by passing `overrideGlobalObjects: false` to `getRequestListener()`. This fixes compatibility with frameworks like Next.js whose response classes extend the native Response.
