59/100

wezterm-agent-mcp

Enables orchestration of multiple AI coding agents (Claude Code, Gemini CLI, etc.) in isolated Wezterm panes, allowing one agent to spawn, monitor, and communicate with others across projects.

Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// key findings
⚠️
Tool descriptions don’t match what handlers do
7 tools describe read intent but their handlers mutate — wez_status (line 831: execFileSync(weztermBin(), ['cli', ...args], {); wez_list (line 831: execFileSync(weztermBin(), ['cli', ...args], {); wez_read_tab (line 831: execFileSync(weztermBin(), ['cli', ...args], {)
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

41/41 tools missing one or more hints — wez_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); wez_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); wez_read_tab (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +38 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Destructive tools are labelled

6 tools perform destructive updates without destructiveHint — wez_launch_grid deletes at line 2141 (unlinkSync(join(dir, entry))); wez_launch_agents deletes at line 2141 (unlinkSync(join(dir, entry))); wez_launch_mixed deletes at line 2141 (unlinkSync(join(dir, entry)))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

Descriptions match behaviour

7 tools describe read intent but their handlers mutate — wez_status (line 831: execFileSync(weztermBin(), ['cli', ...args], {); wez_list (line 831: execFileSync(weztermBin(), ['cli', ...args], {); wez_read_tab (line 831: execFileSync(weztermBin(), ['cli', ...args], {)

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

32/41 tool handlers declare input schemas (78%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tests exist

No test files found

Add tests that exercise each declared tool.

No arbitrary install scripts

Has postinstall/preinstall script — runs arbitrary code on npm install

Remove postinstall/preinstall hooks unless they’re essential.

Tool description accuracy

6 tools have description/behavior mismatches: wez_status: description implies read-only but handler writes/deletes/executes; wez_list: description implies read-only but handler writes/deletes/executes; wez_read_tab: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 8 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
