```
|

|
||||
Access to the underlying request context.
|
||||
|
||||
If called outside of a request context, this will raise a ValueError.
|
||||
Returns None when the MCP session has not been established yet.
|
||||
Returns the full RequestContext once the MCP session is available.
|
||||
|
||||
For HTTP request access in middleware, use `get_http_request()` from fastmcp.server.dependencies,
|
||||
which works whether or not the MCP session is available.
|
||||
|
||||
Example in middleware:
|
||||
```python
|
||||
async def on_request(self, context, call_next):
|
||||
ctx = context.fastmcp_context
|
||||
if ctx.request_context:
|
||||
# MCP session available - can access session_id, request_id, etc.
|
||||
session_id = ctx.session_id
|
||||
else:
|
||||
# MCP session not available yet - use HTTP helpers
|
||||
from fastmcp.server.dependencies import get_http_request
|
||||
request = get_http_request()
|
||||
return await call_next(context)
