Bumps mcp from 1.16.0 to 1.28.1.

Release notes

Sourced from mcp's releases.

v1.28.1

What's Changed

Full Changelog: modelcontextprotocol/python-sdk@v1.28.0...v1.28.1

v1.28.0

Deprecations

Two API surfaces now emit DeprecationWarning ahead of their removal in v2. Nothing is removed in 1.x, and the warnings fire only when the deprecated API is called - importing the modules stays silent.

  • WebSocket transport - mcp.client.websocket.websocket_client and mcp.server.websocket.websocket_servermodelcontextprotocol/typescript-sdk#1783
  • Experimental tasks API - ClientSession.experimental, Server.experimental, ServerSession.experimental, and the experimental_task_handlers= kwarg on ClientSession. Tasks (SEP-1686) were removed from the MCP specification and are expected to return as a separate MCP extension.

If your test suite runs with filterwarnings = ["error"] and exercises these paths, add a scoped ignore such as ignore:The experimental tasks API is deprecated:DeprecationWarning or ignore:The WebSocket .* transport is deprecated:DeprecationWarning.

See #2828 for full details.

Taken, but not merged from this PR: it is being landed as part of a single grouped integration on branch chore/dependabot-2026-08-24, together with the starlette bump of #175.

Reason for grouping: .github/workflows/docker-publish-dev.yml fires on every push to master with no needs: on build-and-test. Each individual merge bumps the version, creates a git tag, publishes ghcr.io/calaos/calaos_base:dev plus a versioned tag, and dispatches a build_deb to calaos/pkgdebs. Merging PRs one by one would burn one full publish cycle per package.

Verdict on the content: good, and verified. mcp==1.28.1 clears GHSA-9h52-p55h-vw2f, GHSA-jpw9-pfvf-9f58 and GHSA-vj7q-gjh5-988w. mcp.server.fastmcp and mcp.server.transport_security — the only two entry points calaos_mcp/server.py uses — are unchanged in 1.28.1.

Note on the green CI above: it means nothing for this change. .github/workflows/ci.yml contains no Python step at all, and the build container ships neither mcp nor pytest, so make check falls back to the stdlib-unittest suites, which never import calaos_mcp.server. Verified out of band instead, in a dedicated python3.11 venv with the full pinned set: create_app() builds, GET /healthz -> 200, POST /mcp initialize -> 200 (protocol 2025-06-18), POST /mcp without Bearer -> 401, tests/python 34 passed / 2 skipped.

This PR will close automatically when the grouped branch lands on master.

build(deps): mcp 1.16.0 -> 1.28.1 (sidecar calaos_mcp)
2927c48 
Reprend la PR Dependabot #174, integree ici en groupe pour n'engendrer
qu'une seule publication docker-publish-dev.

CVE adressees (dependances d'execution du sidecar MCP) :
  - GHSA-9h52-p55h-vw2f (high, corrige en 1.23.0) : protection anti
    DNS-rebinding desactivee par defaut.
  - GHSA-jpw9-pfvf-9f58 (high, corrige en 1.27.2) : les transports HTTP
    servent les requetes de session sans verifier le principal authentifie.
  - GHSA-vj7q-gjh5-988w (high, corrige en 1.28.1) : le transport serveur
    WebSocket ne valide pas Host/Origin.

Portee reelle : le sidecar n'ecoute PAS sur le reseau, il bind un socket
Unix 0660 (src/bin/calaos_mcp/python/calaos_mcp/__main__.py) reverse-proxifie
par calaos_server, et server.py desactive deliberement la protection
DNS-rebinding de MCP (le proxy C++ transmet des Host externes). L'exposition
est donc indirecte, mais mcp reste une dependance d'execution d'un composant
qui traite du trafic HTTP authentifie : la montee est prise.

Verification (le conteneur de build n'a ni mcp ni pytest, donc "make check"
ne couvre PAS ce changement) : venv python3.11 dedie, jeu complet installe,
create_app() construit, GET /healthz -> 200, POST /mcp initialize -> 200,
POST /mcp sans Bearer -> 401, tests/python : 34 passed / 2 skipped.
