Lspace API & MCP Server
Lspace is an open source mcp server and standalone application that eliminates context-switching friction by letting you capture insights from any AI session and instantly make them available across all your tools - turning scattered conversations into persistent, searchable knowledge.
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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

axios Vulnerable to Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy`
axios Vulnerable to Credential Theft and Response Hijacking via Prototype Pollution Gadget in Config Merge
Axios is Vulnerable to Denial of Service via __proto__ Key in mergeConfig
Axios is vulnerable to DoS attack through lack of data size check
OPENAI_API_KEYCrucially, set your .OPENAI_ENDPOINTOPENAI_MODELREPO_BASE_PATHPORTTool 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
7/7 tools missing one or more hints — lspace_list_repositories (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lspace_get_repository_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lspace_add_content (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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.
Tool test coverage
Only 0/7 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
8 child_process/subprocess calls in production code — runs shell commands (src/adapters/githubAdapter.ts:33, src/adapters/githubAdapter.ts:34, src/adapters/githubAdapter.ts:35)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 13 high severity in production deps — axios@1.9.0 (high), axios@1.9.0 (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.
Dependency freshness
2/13 production deps stale: gray-matter@2023-07-12 (3.1y), http-status-codes@2023-09-20 (2.9y)

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
