execute_code (bash/sh/shell) bypassed the workspace boundary guard, so shell
code run through it could read/write/delete paths outside the workspace sandbox
(e.g. cat /etc/passwd) while the same paths were blocked for read_file and the
shell tools. Bring execute_code under the guard (scan only shell-language code,
report the code param), and trust the tool-result spill roots so a legitimate
spilled result stays readable. Adds regression tests.
- Fail closed to a global fallback sandbox root when a conversation has no
per-workspace base path, instead of leaving file/shell tools unconstrained
- Refuse shell commands that delete the workspace root directory itself
- Block workspace-boundary escapes at the policy layer before the approval
prompt, not only at execution time
- Approval bar now shows the actual command / target path being approved
Closes#289 — after an MCP server (re)connects, chat queries kept replying
"from memory" instead of calling MCP tools.
Root cause: agents snapshot their tool set at build time and are cached in
AgentService.agentInstances, but MCP server lifecycle changes never
invalidated that cache (unlike model-config / tool-guard changes which do).
A stale, tool-less agent graph survived until process restart.
Changes:
- Add McpServerChangedEvent; McpServerService publishes it on connect /
disconnect / reconnect / delete / (re)connect-failure / batch refresh /
startup init. AgentService listens and calls refreshAllAgents(), so the
next turn rebuilds against the live MCP tool set. Also closes the boot
race where the web server accepts requests before the @Order(200) MCP
init runner finishes.
- Make create/update/toggle connect asynchronously on a dedicated pool
("mcp-connect") so a slow/unreachable server can no longer freeze the
admin request; status returns immediately as "connecting".
- UI: render the new "connecting" status (pulsing amber dot), show a
friendly "connecting in background" toast, and poll until the status
settles (window widened to ~40s to outlast the default connect timeout).
- UI: MCP config modal no longer closes on outside/backdrop click — only
the × and Cancel buttons close it, so an accidental click can't discard
unsaved config.
Verified E2E: ckjia-shopping (参考价) MCP server connected at runtime with
no backend restart; the cached 通用助手 agent immediately enabled and called
ckjia_shopping_recommend, returning real product cards.

Add an execute_code built-in tool that runs python/bash/node code the agent
writes on the fly, so a documentation-only skill (a SKILL.md with no bundled
scripts) can be acted on. Scoped runs inject the skill's secrets and run in
the skill directory; otherwise a private scratch directory is used. Host
secret env vars are scrubbed from the subprocess. execute_code is an
agent-wide capability, registered in the tool catalog (V143), and screened
by the tool guard with a dedicated set of destructive-pattern rules.
Tests cover python/bash/node execution, scratch-dir fallback, env scrubbing,
argument decoding, and guard gating.
The resilient connect() override started the child process into a local
variable and never set the parent's private process field, so the parent's
closeGracefully() logged "Process not started" and left the child running on
every reconnect/disable. Retain the started process and override
closeGracefully() to destroy it and interrupt the spawned I/O threads.
Also make the inboundSink/errorSink reflection fail loud (the transport is
useless without them — a silent null yielded a connected transport that timed
out on every call), force UTF-8 on the stdio reader/writer, honour a
cooperative closing flag in the reader loops, and drop duplicate PATH entries.
The upstream StdioClientTransport breaks out of its inbound read loop on
any JSON parse error, permanently killing the reader thread. Some MCP
servers write non-JSON debug output to stdout (e.g.
"=== Document parser messages ==="), which triggers this and causes all
subsequent valid JSON-RPC responses to be lost → 30s timeout → agent stuck.
Override connect() in CwdAwareStdioClientTransport to skip non-JSON lines
(log at DEBUG) instead of breaking, keeping the inbound thread alive.
Closes#226
The skill meta-tools (listAvailableSkills, readSkillFile, listSkillFiles, load_skill, runSkillScript) queried the full skill catalog without checking the calling agent's bindings, so an agent scoped to a subset of skills could still read, load, or execute any skill via direct tool calls. Resolve the agent's bound skill ids from the tool context and filter/deny accordingly: a null binding set means no restriction (backward compatible), a non-null set (including empty) restricts access to that set — matching the system-prompt catalog filtering.
Closes#264
Add a single global-proxy switch that routes the backend's outbound traffic
through a configured HTTP/HTTPS/SOCKS proxy, for deployments that cannot reach
overseas APIs directly or must use a unified egress.
- ProxyManager installs the proxy via a default ProxySelector (honored by
java.net.http and HttpURLConnection), the proxy system properties, and a
--proxy-server arg for the browser tool; restores direct egress when
disabled. One switch covers LLM, web search, media generation, channels,
MCP and the browser.
- SOCKS applies to the HttpURLConnection-based egress only; the java.net.http
LLM/streaming path uses an HTTP proxy, and the UI states this.
- New Settings -> Network Proxy page: enable toggle, address, bypass list,
test-connection, and a coverage summary. Config stored as key/value in
mate_system_setting (no migration).

Streaming chat ran render tools on an async thread with no bound request,
so download links lost their host and arrived without a domain. Resolve the
host on the request thread and carry it through ChatOrigin/ToolContext;
falls back to a configurable public-base-url, then a relative path.
1. Relative parent traversal in shell commands (HIGH)
validateShellCommand only scanned absolute path tokens, so commands
like `cat ../mateclaw/CLAUDE.md`, `cd .. && cat foo`, or
`ln -sf ../bar breakout` had no absolute path to trip the check.
From a workspace cwd that's a real escape — `..` segments resolve
against the JVM cwd at file-tool time and reach anywhere the user
can read.
Add a second pass: any token containing `..` as a path segment is
resolved against the workspace root via root.resolve(token).
normalize(); reject when the result falls outside. In-workspace
traversal like `subdir/../sibling` normalizes back inside and
passes. Identifiers without slashes (e.g. version strings with
`1.2..3`) are not treated as paths.
2. Shell validation and process working directory used different
context sources (MEDIUM)
execute_shell_command validated with the explicit ToolContext, but
buildShellProcess called WorkspacePathGuard.getWorkingDirectory()
(no-arg), which only sees the ThreadLocal fallback. Today the
ToolExecutionExecutor sets both so the discrepancy is latent, but
a future direct Spring AI invocation passing only ToolContext would
validate against one basePath and exec against another. Thread ctx
through buildShellProcess and call getWorkingDirectory(ctx) so
validation and execution agree on a single source of truth.
3. Absolute agent override could disable workspace scoping (MEDIUM)
resolveAgentBasePath accepted an absolute override verbatim, even
when it pointed outside the workspace root. An admin (or any
account with agent-edit permission) could set workspaceBasePath="/"
or another team's repo and bypass workspace boundaries entirely.
When a workspace has its own basePath, require absolute overrides
to sit underneath it. The caller in build() catches the rejection,
logs WARN, and falls back to the workspace basePath so chat stays
available rather than crashing agent construction. When the
workspace has no basePath there's no boundary to enforce, so legacy
behavior is preserved.
Test coverage: WorkspacePathGuardShellTest grows from 17 to 23 (six
new cases for `cd ..`, relative parent traversal, relative symlink
escape, deeper traversal, in-workspace normalization, and the
identifier false-positive guard). AgentGraphBuilderBasePathResolutionTest
grows from 7 to 10 (three new cases for in-workspace absolute,
outside-workspace absolute rejection, and no-workspace legacy
behavior). All 45 sandbox-area tests pass with no regressions.
* feat(tool): add send_file tool for sending existing server files as IM attachments
Adds a new built-in tool that reads a file from the server and stashes it
in GeneratedFileCache so the channel adapter (Feishu, DingTalk, etc.)
automatically sends it as a native attachment. This fills the gap where
agents had no way to send existing server files to users — ReadFileTool
only reads text, and render tools only generate new files.
- New SendFileTool with path validation, MIME detection, 20MB limit
- Added "send_file" to tool allowlist in AgentBindingService
- Added i18n error messages (zh-CN + en-US)
* fix(tool): send_file returns URL in scrubber-detectable format
The previous JSON return format caused the LLM to reply with just
"status: sent" without echoing the /api/v1/files/generated/{id} URL.
GeneratedFileScrubber only scans the LLM's final text output, so the
file was never delivered as a native attachment.
Changed to match GeneratedFileLink's format: returns a markdown link
with explicit instructions for the LLM to echo the URL verbatim.
