Interface: ServeStdioOptions

Defined in: mcp-core/src/stdio.ts:17

Properties

headers?

> optional headers?: Record<string, string>

Defined in: mcp-core/src/stdio.ts:19

Static headers applied to every tool call — stdio has no per-request headers.

---

input?

> optional input?: ReadableStream

Defined in: mcp-core/src/stdio.ts:21

Defaults to process.stdin.

---

maxConcurrentRequests?

> optional maxConcurrentRequests?: number

Defined in: mcp-core/src/stdio.ts:38

Most requests (messages with an id) this connection may have in flight at once. One more is answered immediately with a SERVER_BUSY (-32000) JSON-RPC error instead of starting — the stream is a single client, but nothing else bounds how many tool calls it can pile up. Notifications (e.g. notifications/cancelled) are never counted nor refused. Default DEFAULT_MAX_CONCURRENT_REQUESTS (16).

---

maxLineLength?

> optional maxLineLength?: number

Defined in: mcp-core/src/stdio.ts:29

Longest accepted line (one JSON-RPC message), in characters. A longer line is discarded up to its newline — never buffered whole — and answered with an INVALID_REQUEST error. Default DEFAULT_MAX_LINE_LENGTH (4 MiB).

---

output?

> optional output?: object

Defined in: mcp-core/src/stdio.ts:23

Defaults to process.stdout.

> write(chunk): unknown

Parameters

string

Returns
