MCP TypeScript SDK Examples (Client)
December 19, 2025 · View on GitHub
This directory contains runnable MCP client examples built with @modelcontextprotocol/client.
For server examples, see ../server/README.md. For guided docs, see ../../docs/client.md.
Running examples
From the repo root:
pnpm install
pnpm --filter @modelcontextprotocol/examples-client exec tsx src/simpleStreamableHttp.ts
Or, from within this package:
cd examples/client
pnpm tsx src/simpleStreamableHttp.ts
Most clients expect a server to be running. Start one from ../server/README.md (for example src/simpleStreamableHttp.ts in examples/server).
Example index
| Scenario | Description | File |
|---|---|---|
| Interactive Streamable HTTP client | CLI client that exercises tools/resources/prompts, notifications, elicitation, and tasks. | src/simpleStreamableHttp.ts |
| Backwards-compatible client (Streamable HTTP → SSE) | Tries Streamable HTTP first, falls back to legacy SSE on 4xx responses. | src/streamableHttpWithSseFallbackClient.ts |
| SSE polling client (legacy) | Polls a legacy HTTP+SSE server and demonstrates notification handling. | src/ssePollingClient.ts |
| Parallel tool calls | Runs multiple tool calls in parallel. | src/parallelToolCallsClient.ts |
| Multiple clients in parallel | Connects multiple clients concurrently to the same server. | src/multipleClientsParallel.ts |
| OAuth client (interactive) | OAuth-enabled client (dynamic registration, auth flow). | src/simpleOAuthClient.ts |
| OAuth provider helper | Demonstrates reusable OAuth providers. | src/simpleOAuthClientProvider.ts |
| Client credentials (M2M) | Machine-to-machine OAuth client credentials example. | src/simpleClientCredentials.ts |
| URL elicitation client | Drives URL-mode elicitation flows (sensitive input in a browser). | src/elicitationUrlExample.ts |
| Task interactive client | Demonstrates task-based execution + interactive server→client requests. | src/simpleTaskInteractiveClient.ts |
URL elicitation example (server + client)
Run the server first:
pnpm --filter @modelcontextprotocol/examples-server exec tsx src/elicitationUrlExample.ts
Then run the client:
pnpm --filter @modelcontextprotocol/examples-client exec tsx src/elicitationUrlExample.ts
