Sorry, something went wrong.
Overhaul how TypeAgent connects to and manages MCP servers. Connectivity and fidelity: - Move to the v2 MCP client with protocol negotiation. - Support generic stdio servers (command/env/cwd/headers/timeout), not just bundled .js/.py scripts. - Convert each advertised tool independently so one unsupported tool no longer fails the whole server; skipped tools are reported as diagnostics. - Map tool results to TypeAgent results, including text/image/audio/embedded content and error results. Configuration: - Add a normalized MCP server config model (transport, args, env, cwd, enabled tools, trust, scope) with secrets held as credential references, not values. - Import .mcp.json, .github/mcp.json, and .vscode/mcp.json config files, normalizing them into that model. Dynamic lifecycle: - Add/remove/update user-managed MCP servers at runtime and propagate the change to every connected session without a restart. - Persist user-managed servers; keep shipped servers as seeded configuration. Extension management: - Discover MCP servers from a local MCP config file through @Package. - Manage native agents and MCP servers from one command surface, tagged by extension kind, with `@package available --type agent|mcp|all` to filter. Fully covered by offline unit tests; build and local suite green.

Realtime scanning of checkout, pnpm, and test output is a known multi-minute tax on GitHub-hosted and ADO Windows agents. The same suites still run on every required cell. Also record the #2847 required-check span (65.90 min) and the 46.13 min 30% target in the measurements note.

- Skip live_linux on PullRequest. continueOnError already meant a live failure did not fail the gate, but the parent TypeAgent Smoke Tests check stayed queued until live finished (~13 min past Windows smoke on 7e4135e). main and merge-queue still run test:live. - Smoke agents build only agent-shell|agent-cli (with deps) and install Playwright chromium only. playwright.config.ts has one project; shell:smoke launches Electron. Full monorepo build stays on live and build_ts. - On 7e4135e the required span was 36.78 min (ratio 0.558 vs #2847). Live was the pole; Windows smoke setup was 15.5 min of build+browsers for a 1.3 min suite.
