Elasticflow vs Conversation Handoff Mcp

handoff_save

Save a conversation handoff for later retrieval. Use this to pass conversation context to another AI or project. ## Long conversations (>~100KB) If the conversation is large, **save the first chunk with this tool**, then call `handoff_append` repeatedly with the remaining chunks. Doing one giant `handoff_save` can fail with an XML parse / tool-input error because Claude Code encodes tool arguments as XML internally and very large strings can break that encoding. ## Format Selection - **structured** (default): Organize content using the template below. Much faster — reduces output tokens to ~5-20% of the original conversation. Best for most handoffs. - **verbatim**: Save the complete word-for-word conversation. Use only when exact wording matters (e.g., legal text, precise error messages). ## Structured Template (for format="structured") ``` ## Key Decisions - [Decision]: [Rationale] ## Implementation Details [What was built/changed, with relevant code snippets] ## Code Changes [Files modified with brief description] ## Open Issues - [Issue]: [Status/Context] ## Next Steps - [ ] Action item ``` Omit sections that don't apply. Add custom sections if needed.

handoff_list

List all saved handoffs with summaries. Returns lightweight metadata without full conversation content. Opens interactive UI if supported.

handoff_load

Load a specific handoff by key. Returns full conversation content.

handoff_clear

Clear handoffs. If key is provided, clears only that handoff. Otherwise clears all.

handoff_stats

Get storage statistics and current limits. Useful for monitoring usage.

handoff_restart

Restart the shared HTTP server. Useful when the server is in an unhealthy state. All stored handoffs will be lost (data is in-memory).

handoff_merge

Merge multiple handoffs into one. Combines conversations and metadata from related handoffs into a single unified handoff.

handoff_add_comment

Add a comment or annotation to an existing handoff. Comments are included when loading the handoff.

handoff_delete_comment

Delete a comment from a handoff by its comment ID.

handoff_append

Append a conversation chunk to an existing handoff. Use this to upload long conversations in multiple pieces. ## When to use - The full conversation is over ~100KB. - handoff_save fails with an XML parse / tool-input error on a long conversation. Claude Code encodes tool-call arguments as XML internally; very large `conversation` strings can break that encoding (e.g., when the payload contains tag-like substrings). Splitting the upload into smaller chunks avoids that failure mode. ## How to use 1. Call `handoff_save` first with the initial portion (and all metadata: title, summary, etc.) to create the handoff. 2. Call `handoff_append` repeatedly with subsequent chunks until the full conversation is uploaded. 3. Chunks are concatenated as-is — include any newlines or separators inside each chunk. The cumulative conversation size must stay within the storage limit (default 1 MiB).

handoff_search

Search handoffs by tags, text query, project, AI, status, or date range. Returns matching handoff summaries without full conversation content. Use this to discover relevant handoffs in multi-agent workflows.
