sep: 2260
spec_url: https://modelcontextprotocol.io/specification/draft/basic/transports#streamable-http
requirements:
# transports.mdx — POST-initiated SSE streams
- text: 'The server MAY send JSON-RPC requests and notifications before sending the JSON-RPC response. These messages MUST relate to the originating client request.'
excluded: 'Server-side constraint on request association. The conformance harness already operates within an originating client request context, so compliant servers pass by default. Testing violation requires a deliberately misbehaving server and a client that detects unassociated requests, which the harness does not support.'
url: https://modelcontextprotocol.io/specification/draft/basic/transports#streamable-http

# sampling.mdx — Request association requirement (same warning block as elicitation)
- text: 'Servers MUST send sampling/createMessage requests only in association with an originating client request (e.g., during tools/call, resources/read, or prompts/get processing).'
excluded: 'Server-side behavioral constraint. The conformance harness tests servers by sending client requests and checking responses. Servers that only use sampling within request handlers already comply. Testing violation requires a misbehaving server that sends standalone sampling requests.'
url: https://modelcontextprotocol.io/specification/draft/client/sampling

# elicitation.mdx — Request association requirement
- text: 'Servers MUST send server-to-client requests (such as roots/list, sampling/createMessage, or elicitation/create) only in association with an originating client request (e.g., during tools/call, resources/read, or prompts/get processing).'
excluded: 'Server-side behavioral constraint. The conformance harness already operates within originating client request context. Testing violation requires a deliberately misbehaving server.'
url: https://modelcontextprotocol.io/specification/draft/client/elicitation

# roots.mdx — Request association requirement (same warning block as elicitation)
- text: 'Servers MUST send server-to-client requests (such as roots/list, sampling/createMessage, or elicitation/create) only in association with an originating client request (e.g., during tools/call, resources/read, or prompts/get processing).'
excluded: 'Server-side behavioral constraint, duplicated in roots.mdx. Same rationale: conformance harness operates within client request context.'
url: https://modelcontextprotocol.io/specification/draft/client/roots
