When users click Add on two eligible rows before the first finishes (the UI leaves the other row buttons enabled), both calls can read the same mcpServers snapshot and then execute this replacement with only their own new entry. configSet is explicitly replace-not-merge (mcpClientsApi.ts:217-220 and config_ops.rs:41-53), so the later write uninstalls the server written by the earlier call and can likewise erase a concurrent editor/window change. Make this a core-side atomic add/merge, or at least serialize and rebase additions before replacing the document, keeping persistence policy in the core.

For an eligible no-auth server, declareServer first invokes config_set, which queues a background connection for every newly added enabled server (config_ops.rs:43-45,71-74), and this line then starts a second connection to the same server_id. On a slow endpoint those attempts overlap and issue duplicate connection/initialization work; the existing declare_and_connect_registry_echo_server helper at tests/agent_harness_e2e.rs:3973-3975 explicitly disables its declaration to prevent exactly this race. Either rely on the queued connection/status or suppress auto-connect before making the explicit attempt.

resolveHostedEntry now defines the product's registry-to-install contract in React code: which transports and URL schemes count, which schema or environment requirements block installation, and the exact entry persisted. Those are business and persistence rules coupled to upstream metadata; keeping them here prevents other core/RPC callers from sharing the contract and lets the TypeScript heuristic drift from the Rust registry adapter. Move resolution and declaration behind a core RPC and leave the component to present or orchestrate its result.

The new add, OAuth, and refusal flow coverage is added under app/test/playwright/specs, but the repository requires mocked browser or desktop frontend-flow coverage under app/test/e2e/specs/ and use of its shared element helpers. Add corresponding behavior coverage in that required suite (or move the scenario) so this feature is exercised by the canonical flow harness.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Concurrent adds can drop each other's mcp.json entries.
declareServer reads the document, then calls configSet with the full map. configSet replaces the document, and the core uninstalls any server that is missing from it. Suppose the user clicks Add on two rows quickly. Both calls can read the same document before either one writes. The second write then omits the first server, and the core removes it. Nothing serializes calls to runAdd across rows.
The smallest fix is a module-level promise chain that serializes declareServer calls.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Separate declaration failures from refresh failures. In app/src/components/channels/mcp/McpRegistryBrowser.tsx Lines 378-389, declareServer completes before the installedList() lookup. If that lookup fails, the handler still selects the add-failure message even though the server was declared. Add a distinct post-declaration refresh message and select it for that failure path.

Reject URLs containing embedded credentials
new URL accepts values such as https://user:password@mcp.example.com/mcp, and this check then allows the original string to be returned and written to mcp.json. A directory-controlled URL can therefore cause credentials to be persisted and subsequently sent to the endpoint, while also exposing them in local configuration. Reject URLs when parsed.username or parsed.password is non-empty before returning success.

Handle refresh failures after authentication
onDeclared is an async prop and can reject, but this callback fires it without a rejection handler. If refreshing the installed-server state fails after authentication succeeds, the UI silently closes the modal and produces an unhandled promise rejection instead of reporting or preserving the failure state. Handle the rejection explicitly, including suitable user-facing error state or retry behavior.

Canonicalize equivalent hosted URLs before rejecting duplicates
The distinctness check compares URL strings rather than the parsed endpoint. A server whose hosted connections use equivalent spellings such as https://mcp.example.com/mcp and https://mcp.example.com:443/mcp is refused with multiple_urls, even though both connections address the same HTTP endpoint. Normalize URLs using the parsed URL (at least default ports and equivalent formatting) before inserting them into the set, while retaining the original or canonical URL for the resulting entry.

Serialize concurrent MCP declarations
Two simultaneous calls can both read the same document, observe that their names are absent, and then each write a snapshot containing only its own addition. The later configSet can therefore silently erase the other server, contradicting the function's promise to keep every other entry. Use an atomic add-if-absent operation in the API/core or serialize and retry the read-modify-write sequence.
Additional tests observation
Guard the mcp. read-modify-write against concurrent writes
[RULE] read-modify-write-race
declareServer does configGet then configSet as an unguarded read-modify-write. Nothing in runAdd serialises it: two rows can be added concurrently (each row's Add button is only disabled for its own busy phase), or the user can save in the mcp. editor while an add is in flight. Each writer spreads the doc it read, so the later configSet silently drops the earlier writer's entry — a server the user just added disappears from mcp.. No test in the diff exercises concurrent adds or a concurrent editor save, so this regression path is uncovered.

This logs the raw error message returned by registry, declaration, authentication, or connection operations. Those messages may contain credentials, tokens, endpoint details, or user-sensitive backend content, violating the repository rule against logging error messages and potentially exposing secrets through debug logging.

Summary
mcp.json(the existing unified install path), then opens the sign-in flow for OAuth servers or connects directly.Problem
The directory-only design for MCP server discovery means hosted servers with no required inputs or secrets still need hand-written
mcp.jsonentries. The existing rationale holds: we don't guess launch commands or credentials. But for hosted servers a curated directory already vetted, the one-click declaration path should be available.Solution
app/src/components/channels/mcp/registryAdd.ts(new):isAddCandidatepicks deployed, non-Smithery rows without an API key;resolveHostedEntryaccepts only one concrete http(s) URL with no required inputs, secret properties or required env keys, and returns just{url, description};declareServerdoes the read-modify-write viaconfigGet/configSetand refuses an existing key.McpRegistryBrowser.tsx: Add, Added, and Open-page states; inline error display with step-only Retry; hands off toConnectAuthModalfor OAuth.McpServersTab.tsx: re-reads the installed list and statuses after a Registry add (onDeclared).channels.mcp_registry_browsecapability description and the registry README/module docs no longer say "browse-only".
