Changes

MCP chat channels

Layer / File(s)	Summary
Channel runtime policy and registration `scripts/build.ts`, `src/services/mcp/*`, `src/bootstrap/state.ts`	Channels are enabled by default. Explicitly configured server channels no longer require OAuth, development mode, or the plugin allowlist. Tests cover registration without these gates.
Channel entry points and UI handling `src/main.tsx`, `src/components/LogoV2/ChannelsNotice.tsx`	CLI help exposes tagged server and plugin formats. The channel notice removes the claude.ai OAuth requirement and development-channel warning.
Channel setup documentation and local wiring `docs/advanced-setup.md`, `web/src/pages/docs/configuration.astro`, `web/package.json`, `.vscode/settings.json`	Documentation describes Telegram MCP channels, session opt-in, plugin syntax, and provider configuration. Local package wiring and terminal approvals are added.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 5a123

This should not merge yet: an unapproved plugin channel can bypass trust checks, CI web installation can fail, and the new setup guidance can select the wrong provider configuration. The workspace command approvals also expose contributors to unintended package execution.

Full details: No Hidden Policy Change

Explanation

The PR introduces explicit permission and trust-model changes without maintainer alignment in the authored description. It adds .vscode/settings.json with chat.tools.terminal.autoApprove enabled for bun, npm install, and npx --yes bun; this is unrelated to Telegram channel support. It also removes the OAuth gate, changes the tengu_harbor fallback from false to true, and allows explicitly listed server:<name> entries to bypass the approved-channel allowlist. These changes alter authentication, routing availability, and trust policy. The authored PR text only says #2175 Issue Solved, and the commit body contains no policy rationale or approval record. The repository guidance says unrelated changes and new features require prior maintainer discussion.

Resolution

Remove the unrelated .vscode/settings.json permission auto-approval change, or move it to a separate maintainer-approved PR. Update this PR with an explicit policy section that documents the OAuth removal, tengu_harbor default change, and trust model for server:<name> entries. Obtain and record maintainer/security approval for those policy decisions before merging.

Greptile Summary

This PR enables explicitly configured MCP channel servers, including Telegram, for non-OAuth providers and documents the new CLI flow.

Enables the channel build/runtime gates and exposes --channels server:<name>.
Removes OAuth and development-only restrictions for explicitly selected server channels.
Updates channel notices, tests, and CLI/web documentation.
Adds a local root-package dependency to the web manifest.

Confidence Score: 2/5

The PR is not safe to merge until the plugin-channel allowlist bypass and frozen web-install failure are fixed.

Plugin runtime names can now be treated as trusted server entries and receive inbound-message registration without plugin approval, while the unmatched web manifest and lockfile cause the clean CI installation to fail.

Files Needing Attention: src/services/mcp/channelNotification.ts and web/package.json

Security Review

A plugin MCP server can be selected through its full runtime name as a server: entry, bypassing the marketplace and approved-plugin checks before inbound messages are delivered to the active model session.

Important Files Changed

Filename	Overview
src/services/mcp/channelNotification.ts	Removes OAuth and server development gates, but permits plugin runtime names to bypass plugin marketplace and allowlist validation.
src/main.tsx	Makes the channel option visible and documents the server/plugin selector syntax.
src/services/mcp/channelNotification.test.ts	Updates expected behavior for non-OAuth and ordinary server entries but does not cover a server-kind entry matching a plugin runtime name.
src/services/mcp/channelAllowlist.ts	Enables channels by default when no runtime feature value exists.
web/package.json	Adds an unused local root dependency without the corresponding web lockfile update, breaking frozen installation.
docs/advanced-setup.md	Documents Telegram MCP channel configuration, provider independence, and explicit opt-in.
web/src/pages/docs/configuration.astro	Adds matching Telegram channel setup guidance to the documentation site.

    }
  } else {
    // server-kind: allowlist schema is {marketplace, plugin} — a server entry
-    // can never match. Without this, --channels server:plugin:foo:bar would
-    // match a plugin's runtime name and register with no allowlist check.
-    if (!entry.dev) {
-      return {
-        action: 'skip',
-        kind: 'allowlist',
-        reason: `server ${entry.name} is not on the approved channels allowlist (use --dangerously-load-development-channels for local dev)`,
-      }
-    }
+    // Manually configured MCP servers are trusted by their explicit
+    // server:<name> session entry. Plugin entries use the marketplace
+    // allowlist above because their implementation is third-party code.


Plugin allowlist bypass

When --channels server:plugin:slack:main names a plugin's full runtime server name, server-kind matching takes precedence and this branch registers the channel without marketplace or plugin-allowlist validation, allowing an unapproved plugin to inject inbound messages into the active model session. How this was verified: Plugin runtime names use the plugin:<pluginName>:<serverName> format that server-kind entries match exactly before reaching this now-unrestricted branch.

Inline comments:
In @.vscode/settings.json:
- Around line 4-5: Remove the auto-approval entries for “npm install” and “npx
--yes bun” from the VS Code settings so both package installation commands
require explicit confirmation.

In `@docs/advanced-setup.md`:
- Around line 63-65: Add CLAUDE_CODE_USE_OPENAI=1 to the documented
OpenAI-compatible provider setup alongside OPENAI_BASE_URL, OPENAI_API_KEY, and
OPENAI_MODEL, so startup preserves the intended OpenAI route instead of applying
the Gitlawb Opengateway default.

In `@src/services/mcp/channelNotification.ts`:
- Around line 327-329: Update parseChannelEntries() or findChannelEntry() to
reject server: entries whose server name begins with plugin:, preventing plugin
runtimes from bypassing gateChannelServer() marketplace and approved-plugin
checks. Preserve valid manually configured server entries, and add a regression
test covering the server:plugin:foo:bar collision.

In `@web/package.json`:
- Line 16: Remove the unused `@gitlawb/openclaude` entry from the web package
manifest so it matches the existing bun.lock and the web install remains
frozen-lockfile compatible.
