Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe internal OpenCode configuration API now supports merge-mode PATCH updates, redacts secret values in responses, and exposes configured MCP server views with live status. MCP settings workflows now use configuration updates for configured servers. Documentation also covers themes and the ChangesConfiguration and MCP workflows

Merge Risk: 🟡 Moderate · up to Internal configuration reads can still disclose some credentials, including credentials embedded in MCP URLs. Fix those exposures before merging; the setup guide also overstates what the build and lint commands cover. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new configuration workflows improve secret handling, but they do not consistently keep sensitive values out of assistant-facing responses. Access controls limit who can reach those responses, and the remaining reload and recovery questions prevent a stronger assurance. Retained concerns

Sensitive Data Exposure
Reachability: Internal
Exploitability: Moderate
CWE: CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor
Redact provider credential fields by normalized suffix.
isSecretKey only checks exact normalized names. Provider fields such as secretAccessKey, accessKeyId, sessionToken, githubToken, and client_secret_key therefore remain plaintext in redacted responses.
The exposure is confined to the token-protected internal API and its ocm agent-facing tool. The manager tool exposes the GET and PATCH routes, but not PUT; PUT remains reachable only through other authenticated internal API clients.
Include secretkey so client_secret_key is covered:
🔒 Proposed fix
+const SECRET_KEY_SUFFIXES = ['token', 'secret', 'secretkey', 'password', 'passphrase', 'apikey', 'privatekey', 'accesskey', 'accesskeyid', 'credential', 'credentials', 'authorization']
+
function isSecretKey(key: string): boolean {
- return SECRET_KEYS.has(normalizeSecretKey(key))
+ const normalized = normalizeSecretKey(key)
+ return SECRET_KEYS.has(normalized) || SECRET_KEY_SUFFIXES.some((suffix) => normalized.endsWith(suffix))

Correct the package coverage in the setup guide.
The root build and lint scripts cover only the CLI, backend, and frontend. They do not run commands for shared, so replace “all packages” with the packages that these scripts cover.

Redact literal credentials from remote MCP URLs.
isMcpServerConfig accepts remote entries with literal credentials, and toMcpServerView returns config.url unchanged. The internal MCP listing can therefore expose values such as URL userinfo or apiKey query parameters to the manager tool. {env:...} and {file:...} references are not expanded by this route, so they must remain unchanged. Redact only credential-bearing URL components and preserve benign query parameters.

Problem
The internal assistant API returned the full OpenCode configuration, including API keys, bearer tokens, and headers, and required sending the entire merged document back to change a single value. MCP servers could only be inspected by reading the whole config.
