lossless-context-mcp (NORTHTEKDevs/lossless-context-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
MCP server providing lossless file reads with deduplication, per-repo token metering, and HMAC-signed context receipts. Enables auditable, vendor-neutral measurement of what an AI agent saw.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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
11/11 tools missing one or more hints — read_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_files (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); outline (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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 3/11 tools referenced in tests (27%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
4 child_process/subprocess calls in production code — runs shell commands (bench/smoke.mjs:18, bench/smoke.mjs:47, bench/smoke.mjs:207)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
