LabelBridge MCP
This MCP server enables human-in-the-loop semantic labeling by creating self-contained HTML forms for ambiguous data and securely retrieving labeled results.
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.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
create_labeling_sessionLabelBridge(레이블브릿지) creates a blank-only HTML labeling form from an array. It never suggests answers; a human fills every semantic field, then returns encrypted answer JSON for one-time ingest.
ingest_labeling_resultLabelBridge(레이블브릿지) ingests answer JSON created by its HTML form, validates hashes and the one-time capability, consumes it atomically, and returns AI-native labeled dictionaries.
inspect_labeling_sessionLabelBridge(레이블브릿지) checks one-time labeling status without exposing the capability token or raw human labels.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

Only 0/3 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/3 tool handlers wrap calls in try/catch (33%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/3 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
12 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.23.3 (high), @modelcontextprotocol/sdk@1.23.3 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
