[dependabot]

Bumps the all-dependencies group with 3 updates: fastmcp, platformdirs and posthog.

Updates fastmcp from 3.4.6 to 3.4.7

Release notes

Sourced from fastmcp's releases.

v3.4.7: Know Your Audience

FastMCP 3.4.7 restores CIMD private_key_jwt authentication for OAuthProxy deployments at a bare origin. Client assertions are now validated against the exact token endpoint advertised in authorization server metadata, eliminating the doubled-slash audience mismatch.

What's Changed

Security 🔒

• Backport CIMD assertion audience fix to v3 by @​jlowin in PrefectHQ/fastmcp#4799

Docs 📚

• Docs: add v3.4.7 changelog entries by @​jlowin in PrefectHQ/fastmcp#4810

v3.4.7: Know Your Audience

FastMCP 3.4.7 fixes CIMD private_key_jwt authentication on bare-origin OAuth proxy deployments by validating client assertions against the exact token endpoint advertised in OAuth metadata.

Security 🔒

• Backport CIMD assertion audience fix to v3 by @​jlowin in #4799

Full Changelog: v3.4.6...v3.4.7

v3.4.6: Trust, but Proxy

FastMCP 3.4.6 backports trusted-proxy support for SSRF-protected OAuth metadata and JWKS fetches. Deployments can now route these requests through a mandated corporate proxy while preserving custom CA certificates; FastMCP refuses the fetch when no proxy is configured instead of risking an unprotected direct request.

Fixes 🐞

• Backport #4412 to 3.x: support trusted SSRF proxies by @​jlowin in #4755

v4.0.0b1: Fourgone Conclusion

FastMCP 4 makes stateful MCP applications work on the sessionless 2026-07-28 protocol while one deployment continues serving handshake-era clients. Tools can ask follow-up questions across requests, preserve authenticated user state, and move long-running work into background tasks without sticky sessions. Protocol extensions and enterprise identity become first-class surfaces, and most FastMCP 3 servers upgrade unchanged even though MCP Python SDK v2 rewrote the engine underneath them. Server-initiated sampling and roots are removed from the server API; the upgrade guide covers their replacements.

New Features 🎉

• Migrate to MCP Python SDK v2 by @​jlowin in #4437
• Teach fastmcp.Client the modern protocol: mode negotiation, MRTR driver, response cache by @​jlowin in #4450
• Forward-port Hugging Face auth provider by @​jlowin in #4475
• Add server-side identity assertion (SEP-990 ID-JAG) by @​jlowin in #4483

4.11.3 (2026-08-13)

---

• python -m platformdirs now lists :func:~platformdirs.user_desktop_dir, which was missing from the properties it prints. :pr:523
• Stop :func:~platformdirs.site_data_dir, :func:~platformdirs.site_config_dir and :func:~platformdirs.site_applications_dir raising IndexError on Unix and macOS when $XDG_DATA_DIRS or $XDG_CONFIG_DIRS holds only separators and whitespace, such as ":". These values now fall back to the platform defaults, and each entry is stripped of surrounding whitespace. :pr:523

---

4.11.2 (2026-08-10)

---

• Stop :meth:~platformdirs.PlatformDirs.iter_cache_dirs, :meth:~platformdirs.PlatformDirs.iter_state_dirs, :meth:~platformdirs.PlatformDirs.iter_log_dirs and :meth:~platformdirs.PlatformDirs.iter_runtime_dirs yielding the same directory twice on Unix when use_site_for_root is active - :pr:469 fixed this for the config and data iterators only. On macOS, :meth:~platformdirs.PlatformDirs.iter_cache_dirs now yields the Homebrew and /Library/Caches entries separately rather than one os.pathsep-joined string when multipath is set. :pr:520

---

4.11.1 (2026-08-07)

---

• Fix :func:~platformdirs.user_desktop_dir on Windows builds without ctypes. CSIDL_DESKTOPDIRECTORY appeared only in the ctypes lookup table, so the registry and environment variable resolvers raised ValueError for it. :pr:519

---

4.11.0 (2026-07-21)

---

• Declare support for Python 3.15 and run the test suite against it, currently in beta. :pr:512

---

4.10.1 (2026-07-18)

---

• Stop leaking memory on repeated Windows folder lookups. get_win_folder_via_ctypes defined a fresh ctypes structure on every call, and each one registered a pointer type that was never released; the resolver is now built

Looks like these dependencies are updatable in another way, so this is no longer needed.
