Conversation Handoff MCP (trust-delta/conversation-handoff-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.
Enables transferring conversation context between different AI chats or projects with automatic server discovery and memory-based storage. Supports saving, loading, and managing conversation histories in a human-readable Markdown format.
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.

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
10/10 tools missing one or more hints — handoff_save (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); handoff_load (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); handoff_clear (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 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 inputs are validated
8/10 tool handlers declare input schemas (80%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 3/10 tool handlers wrap calls in try/catch (30%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 1/10 tools referenced in tests (10%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.25.3 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
3 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
