fix(security): stop the agent from re-enabling tools an admin disabled (#6357)
* fix(security): stop the agent from re-enabling tools an admin disabled settings.json:disabled_tools is the only global tool-permission boundary the Settings > Agent Tools panel offers, yet manage_settings exposed an `enable_tool` action that removed entries from it. Any agent turn could undo the admin's restriction, and because the agent reads untrusted web pages, emails and documents, a planted instruction could re-enable bash, email or any other tool that had been switched off. The denylist can now only be narrowed from a turn: `disable_tool` and `list_tools` keep working, `enable_tool` is refused with a message that points the user to Settings > Agent Tools, and the action is dropped from the function schema, the prompt rule and the tool index so models are not steered into calling it. The free-form set/delete/reset actions were already unable to reach `disabled_tools`; a test now pins that. Fixes #5523 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UAB5sz5srMKR7rbeDFtdMH * fix(settings): close internal API tool-policy bypass Refuse global tool-policy replacement from internal-token requests even when an admin owner is impersonated, and block the same write in app_api. Route explicit image re-enable requests to list_tools with a Settings pointer. Keep disabled_tools outside general settings actions even if a default is added later. Remove the retired action from capability metadata. Validation: 573 focused tests passed; the running app rejected handler, generic API and encoded-path internal HTTP attempts while preserving human administrator controls. * fix(mcp): block agent writes to per-server MCP tool policy PATCH /api/mcp/servers/{id}/tools only checked require_admin, which accepts the internal tool token, and app_api still forwarded it, so an agent turn could re-enable MCP tools an admin had switched off. Refuse the internal token on that route (same check as POST /api/tools) and add PATCH /api/mcp/servers to the app_api blocklist, with regression tests.

fix(security): add SSRF validation to manage_endpoints agent tool (#6327)
The manage_endpoints agent tool accepts arbitrary user-supplied base_urls and writes them to the database without calling check_outbound_url(), while the HTTP route (POST /api/model-endpoints) enforces full SSRF hardening. A prompt-injection payload smuggled into a skill, note, fetched page, or email could instruct the model to register a cloud-metadata or internal-network endpoint via this tool path. Add the same check_outbound_url() guard used by the HTTP route to the agent tool's 'add' action. Also sanitize the error message in the except block to avoid leaking raw exception text. Add 8 regression tests covering: cloud metadata, non-HTTP schemes, loopback (local-first), strict mode, safe URLs, empty URLs, gopher scheme, and error message sanitization.

refactor(model-routing): centralize explicit foreground fallback policy (#6020)
* refactor(model-routing): centralize explicit foreground fallback policy Make foreground fallback an explicit per-user, availability-only policy shared by streaming Chat, non-stream Chat, and Agent runs. Preserve strict defaults, owner/model and credential boundaries, pinned Agent routes, and truthful per-round provenance/accounting. Carry provider-reported model identifiers through native streaming adapters, non-stream responses, and caches, and keep legacy default_model_fallbacks as tombstoned raw storage that generic settings APIs and agent tools cannot expose or mutate. * fix(agent-loop): restore rebase-dropped qwen routing, workspace prompt, and temperature clamp * fix(model-routing): thread selected endpoint identity, fix cost classification and fallback eligibility * fix(chat): restore stream helpers and harden run stop lifecycle * fix(model-routing): let numeric provider codes win over symbolic rate-limit statuses * fix(agent-loop): apply qwen temperature and notes-tool clamps per fallback candidate * fix(chat): honor queued stop across resend and reload canonical terminal on EOF * fix(chat): track stop queue and cleanup ownership by per-send generation * fix(agent-loop): preserve requested temperature for non-qwen fallback candidates * fix(chat): reserve send ownership before any await and scope stop to the current send * fix(chat): clear the previous run identity at send reservation --------- Co-authored-by: RaresKeY <158580472+RaresKeY@users.noreply.github.com> Co-authored-by: StressTestor <212606152+StressTestor@users.noreply.github.com> |

fix(agent): execute fenced tool calls with inline args and route bare email tool names (#3681)
* fix(agent): execute fenced tool calls with inline args and bare email tool names
Two bugs made local (Ollama) models unable to use email tools, leaving
raw fences like ```list_email_accounts {}``` in the chat:
1. _TOOL_BLOCK_RE required a newline right after the fence tag, so a
tool call with args on the same line ("```list_email_accounts {}")
never matched and was never executed. The fence now matches with
optional spaces/newline after the tag.
2. Even when parsed, bare email tool names had no dispatch branch in
tool_execution.py and fell through to "Unknown tool type". They now
route to the email MCP server as mcp__email__<name>, matching how
function_call_to_tool_block already maps them for native callers.

* fix(security): block all bare email tool names for non-admins; harden fence-tag regex
Review follow-up on #3681 (thanks @vgalin):
1. Routing bare email names made 10 of the 14 email tools executable by
non-admin owners — is_public_blocked_tool() runs on the bare name
before dispatch, and NON_ADMIN_BLOCKED_TOOLS only listed 4. Define the
full email tool set once (BUILTIN_EMAIL_TOOLS in tool_security.py) and
derive the blocklist, the fence tags (TOOL_TAGS), the bare-name
dispatch, and the native-call mapping from it so they can't drift.
This also fixes 4 tools (search_emails, draft_email, draft_email_reply,
ai_draft_email_reply) that were missing from the old tool_schemas copy
and therefore unreachable even for native function-calling models.
2. The relaxed fence regex from the previous commit could prefix-match
longer fence tags: ```python3 parsed as tool "python" with content
"3\nprint(...)" and executed as code. Add a (?![\w-]) boundary after
the tag.
Tests: test_public_agent_policy_blocks_sensitive_tools now covers all 14
bare email names + the mcp__email__ form; new tests/test_fenced_inline_args.py
pins inline-args parsing, the python3/hyphenated-tag non-matches, and
strip/parse display mirroring.

* fix(security): gate bare and mcp-qualified email names together; stop executing Markdown info strings
Review follow-up on #3681 (thanks @RaresKeY):
1. P1: execute_tool_block() checked disabled_tools / the turn ToolPolicy
only against the incoming block name, then the bare-email branch
qualified it to mcp__email__<name> and called the MCP manager. Plan
mode and the MCP settings toggle write the QUALIFIED name into the
denylist, so a bare fence like ```list_emails``` sailed past a
mcp__email__list_emails entry. Both gates now match on both
spellings (bare <-> mcp__email__-qualified), in either direction.
2. P2: the relaxed fence regex accepted arbitrary same-line text after
a recognized tag, which made ordinary Markdown info strings
executable: ```python title="example.py" ran as a python tool call.
Same-line content now only counts as tool input when it starts with
{ or [ (JSON args); anything else leaves the fence as display text,
and strip_tool_blocks mirrors that (the fence stays visible).
Tests: disabled-tools alias regression (qualified entry blocks bare
name and vice versa, never reaching the MCP manager), ToolPolicy alias
regression, python/bash title="..." non-execution + display retention,
and inline JSON-array args still parsing.

* fix(security): reject brace-style fence metadata; cover the full email set in the friendly toggle
Review follow-up round 3 on #3681 (thanks @RaresKeY):
1. Brace-style fence metadata no longer executes. The previous narrowing
still treated any same-line {/[ after a recognized tag as tool input,
so ```bash {title="setup"} ran as a bash call. The fence header is now
captured separately and judged by one predicate shared between
parse_tool_blocks and strip_tool_blocks (_fenced_tool_call), so the
execute and display decisions can't disagree: same-line content only
counts as inline args when the tag is NOT a code tag (bash/python
never take same-line args — that text is Markdown fence attributes)
AND the inline text (plus any continuation lines) parses as standalone
JSON. ```bash {title="setup"}, ```python {"title":"example.py"} and
```list_emails {title="x"} all stay visible and inert.
2. The friendly `disable_tool email` toggle covered 3 of the 14 email
tools (mcp__email__{list_emails,read_email,send_email}); the other
bare aliases this PR routes stayed executable after an operator
disabled email. The alias now derives from BUILTIN_EMAIL_TOOLS in
BOTH spellings — bare (function-schema hiding, bare-fence dispatch)
and mcp__email__* (MCP schema hiding, qualified runtime blocks) —
so the toggle and the runtime gate can't drift apart.
Tests: brace/bracket metadata regressions for parse and strip symmetry
(code tags, invalid-JSON inline on a JSON tool, multi-line inline JSON
still parsing), and disable_tool/enable_tool email covering all 14 names
in both spellings.

* fix(email): close remaining email-tool registry drift; classify every email tool for plan mode
Deep self-review follow-up on #3681. Three review rounds each found another
hand-maintained copy of the email tool list that had drifted; this commit
hunts down ALL remaining copies and pins them to BUILTIN_EMAIL_TOOLS.
The same 5 tools (search_emails, draft_email, draft_email_reply,
ai_draft_email_reply, download_attachment) were missing from every
advertising surface, so they were dispatchable but never offered:
- FUNCTION_TOOL_SCHEMAS: native function-calling models never saw them
(the round-1 fix covered dispatch only); schemas added, mirroring the
email server's inputSchema definitions.
- TOOL_SECTIONS: fenced-block models were never told about them; prompt
sections added.
- tool_index: absent from the RAG embedding registry (never retrievable),
the email keyword hints, and the scheduled assistant's always-available
set — the latter two now derive from BUILTIN_EMAIL_TOOLS.
- agent_loop._DOMAIN_TOOL_MAP["email"], tool_policy._COMMON_TOOL_NAMES,
the assistant tool-selector UI groups (assistant.js), and the default
Assistant crew seed (task_scheduler) now derive from / cover the set.
Plan mode now classifies every email tool explicitly:
- list_email_accounts and search_emails join PLAN_MODE_READONLY_TOOLS.
Without this, list_email_accounts sat in the plan-mode bare denylist
(schema-derived) while its qualified form passed the MCP read-only
filter — and the round-2 bare/qualified alias gate would have blocked
the qualified call too, regressing read-only email discovery in plan
mode.
- draft_email, draft_email_reply, ai_draft_email_reply, and
download_attachment join the fail-closed mutator backstop (drafts
create documents; download_attachment writes to disk).
Tests: tests/test_email_registry_sync.py pins every registry (including
the email server source and assistant.js) to BUILTIN_EMAIL_TOOLS and
asserts the plan-mode partition, so the next email tool can't drift; a
parse/strip mirror grid covers 192 fence shapes (tag x header x body)
asserting executed <=> stripped.

* refactor: move the email alias rule into tool_security; extract the assistant seed constant
Code-quality pass over the PR's own changes:
- The bare<->qualified email aliasing rule lived inline in the generic
dispatcher (_execute_tool_block_impl). It is policy knowledge, so it
moves next to BUILTIN_EMAIL_TOOLS as email_tool_policy_names(); the
dispatcher just consumes it, and the rule gets its own unit test
(including the mcp__email__<not-a-tool> and mcp__other__ non-alias
cases).
- The default Assistant's enabled_tools list was an inline literal
inside the CrewMember seed, and its registry-sync test asserted a
source-code substring. Extracted to DEFAULT_ASSISTANT_ENABLED_TOOLS
so the test imports and checks the actual value.
- _fenced_tool_call return type tightened to Optional[Tuple[str, str]].
No behavior change; suite green (3295 passed).

* revert: move the email registry consolidation to a follow-up PR
Per review feedback on scope, this PR stays narrow: fenced inline-args

refactor(tools): migrate config/integration admin tools to the registry (#4742)
Part of #3629 (the `admin_tools.py` bullet). Moves the config/integration admin tools off the legacy elif dispatch chain in tool_implementations.py onto the agent_tools registry: manage_endpoints, manage_mcp, manage_webhooks, manage_tokens, manage_settings The do_* implementations (and manage_mcp's command-allowlist / RCE guard: _validate_mcp_command, _mcp_allowed_commands, and the _MCP_* constants) move verbatim into the new src/agent_tools/admin_tools.py. They register through a single ADMIN_TOOL_HANDLERS map that TOOL_HANDLERS.update()s, and the five elif branches plus their imports are dropped from tool_execution.py, so these tools now flow through _direct_fallback like the other migrated clusters. The names are re-exported from src.agent_tools for back-compat. Dedup: - _parse_tool_args was duplicated in tool_implementations.py and document_tools.py. It now lives once in src.tool_utils (which imports nothing from the project beyond src.constants, so this introduces no cycle) and both call sites import it from there. The orphaned `import json` in document_tools is removed with it. - The five tools share one _owner_adapter(fn) factory that threads ctx["owner"] into the owner-taking do_* signature, instead of five near-identical wrappers. Tests: new tests/test_admin_tools_registry.py pins the registration, the re-export back-compat, the owner-threading adapter, and the single-source _parse_tool_args (across admin_tools and document_tools). Existing MCP / settings / webhook suites are repointed at the new module. |
