Updates uvicorn from 0.52.1 to 0.54.0

Release notes

Sourced from uvicorn's releases.

Version 0.54.0

📨 Send metadata after the response body

uvicorn 0.54.0 adds response trailers and 103 Early Hints to its experimental HTTP/2 implementation through zttp.

uv add uvicorn==0.54.0 "zttp>=0.0.34"
  • Send HTTP/2 response trailers (#3146). The ASGI http.response.trailers extension lets applications send metadata, such as checksums, after the response body. Clients must send TE: trailers to receive them. Multiple trailer messages are combined before completing the response.
  • HTTP/2 remains experimental and opt-in. Enable it with --http zttp --http2. Upgrade-based h2c and WebSockets over HTTP/2 remain unsupported.

💡 Hint at resources before the final response

  • Send 103 Early Hints over HTTP/2 (#3137). Applications can use the ASGI http.response.early_hint extension to send resource hints before the final response. Each supplied link becomes a separate Link header.

Full changelog: 0.53.0...0.54.0

Version 0.53.0

🌐 Opt-in HTTP/2 support

uvicorn 0.53.0 adds experimental HTTP/2 through zttp, alongside a new zuvloop integration and connection-handling improvements.

uv add uvicorn==0.53.0
  • Serve HTTP/1.1 and HTTP/2 with zttp (#2982, #3101). Install zttp, then enable HTTP/2 with --http zttp --http2. Uvicorn negotiates HTTP/2 over TLS with ALPN and supports cleartext prior knowledge.
  • HTTP/2 remains experimental. Upgrade-based h2c and WebSockets over HTTP/2 are not supported.

⚙️ More event loop choice

  • Run Uvicorn with zuvloop (#3104). Install zuvloop separately and select it explicitly with --loop zuvloop on CPython 3.14 or newer.

🛡️ More reliable connections and proxies

  • Honor Connection: close token lists (#3103). Uvicorn now parses comma-separated tokens case-insensitively across HTTP implementations.
  • Trust IPv6 loopback proxies by default (#3119). The default FORWARDED_ALLOW_IPS value now includes ::1.
  • Keep upgraded WebSockets alive (#3107). Uvicorn cancels the HTTP keep-alive timer when the connection becomes a WebSocket.

Full changelog: 0.52.4...0.53.0

Version 0.52.4

Fixed

  • Remove duplicate Date headers from accepted WebSocket handshakes with websockets-sansio (#3078)

Updates mcp from 2.0.0 to 2.2.0

Release notes

Sourced from mcp's releases.

v2.2.0

pip install -U mcp. Docs: https://py.sdk.modelcontextprotocol.io/

A few defaults changed in this release. If you run a server or client on 2.x, skim these first:

Behaviour changes

HTTP client redirects are only followed within the endpoint's origin (#3397)

  • Client("https://..."), streamable_http_client and sse_client follow a redirect only if it stays on the same scheme, host and port (or upgrades http to https on the same host).
  • A redirect anywhere else is not followed: the call fails with MCPError and the session stays usable (an SSE connect fails with httpx2.HTTPStatusError). If that other URL is the server you meant, use it as the endpoint URL.
  • The follow_redirects setting on an httpx2.AsyncClient you pass in is no longer used for MCP requests, so you don't need it for the trailing-slash redirect any more.
  • The OAuth providers apply the same rule to their own requests.

Idle Streamable HTTP sessions now expire (legacy <=2025-11-25 spec( (#3395)

  • A stateful session with nothing in flight for 30 minutes is closed. The client's next request gets a 404 and it has to initialize again.
  • Clients that keep the GET stream open (the SDK's Client does) are not affected. Neither are stateless servers or 2026-07-28 connections.
  • A server also holds at most 10 000 sessions at once; beyond that, new sessions get a 503.
  • To turn either off: mcp.run(transport="streamable-http", session_idle_timeout=None, max_sessions=None) (also on streamable_http_app() and run_streamable_http_async()).

The OAuth client checks the authorization server's issuer on the legacy path too (#3398)

  • For servers without protected resource metadata, authorization server metadata whose issuer isn't the server's own origin is now rejected with OAuthFlowError: Authorization server metadata issuer mismatch. The protected-resource-metadata path has done this since 2.0.
  • A 403 that isn't an insufficient_scope challenge is returned to the caller instead of retried.
  • If protected resource metadata can't be fetched because of a 5xx/429, the flow now stops instead of falling back to the legacy endpoints.

Two new MCPDeprecationWarnings (#3435, #3447)

  • ClientCredentialsOAuthProvider / PrivateKeyJWTOAuthProvider without issuer=. Pass your authorization server's issuer URL; 3.0 will require it.
  • AuthSettings with resource_server_url set but validate_token_resource unset. Set it to True or False; 3.0 defaults it to True.
  • Both keep working as before in 2.x; this mostly matters if your tests turn warnings into errors.

New

  • AuthSettings.validate_token_resource: only accept tokens your TokenVerifier reports as issued for this server (#3447).
  • issuer= on ClientCredentialsOAuthProvider and PrivateKeyJWTOAuthProvider (#3398).
  • session_idle_timeout= and max_sessions= on the Streamable HTTP server entry points (#3395).

Fixes

  • A client DELETE frees its session immediately, and a refused opening request no longer leaves a session behind (#2455, #3228, #3300).
  • $refs in a tool's outputSchema resolve within that schema only; an unresolvable one surfaces as RuntimeError: Invalid schema for tool ... (#3394).

Known gaps

The tasks extension (SEP-2663), DPoP (SEP-1932) and the jwt-bearer grant are not implemented yet; https://github.com/modelcontextprotocol/python-sdk/blob/main/ROADMAP.md tracks them.
