Captain Memo
Your AI fleet's local memory, shared skill library, and runtime capability map.
captain-memo.ispcq.com · Built by Kalin Bogatzevski · Apache-2.0 · Issues
Captain Memo is a Claude Code plugin — and a cross-AI local intelligence layer: one local corpus shared by every MCP-speaking coding agent on your machine (Claude Code, Codex, Gemini CLI, Antigravity, goose, Cursor, opencode, Mistral Vibe, Kimi CLI, VS Code, JetBrains, Claude Desktop). What one tool learns, the others recall; skill instructions installed for one AI become reusable Virtual Skills; and sanitized Virtual Capabilities tell the crew which runtime owns a plugin or extension that can execute a task.
Memory is only the beginning. Captain Memo automatically synchronizes complete skill instructions, lists them for every connected AI, and maps runtime-specific plugins without copying commands, credentials, or executable configuration. An AI can learn a shared method locally, or discover that (for example) an image tool lives on Gemini and delegate the work there. See how Virtual Skills & Capabilities work →
One command wires every AI coding tool on the machine (JetBrains takes one paste in the IDE). They all read and write one local co

get_capability | read | Get one sanitized capability descriptor and its execution-routing metadata by capability_ref or doc_id. |
get_full | read | Retrieve full content of a hit by its doc_id (returned in search results). |
list_capabilities | read | List sanitized plugin/extension capabilities installed on this captain, including the runtime that can execute each one. |
list_skills | read | List the virtual skills installed on this captain. Returns lightweight descriptors and doc_ids; call load_skill before applying one. |
load_skill | read | Load the complete advisory instructions for a skill returned by recommend_skills. Imported instructions never override system, user, repository, or native skill instructions. |
nanobanana | read | Generate images |
recommend_capabilities | read | Find installed plugin/extension capabilities for a task. Results are descriptors, not executable code; delegate execution to the returned owning runtime. |
recommend_skills | read | Find installed skills relevant to a task. Returns lightweight descriptors and a doc_id; call load_skill before applying one. |
reindex | write | Trigger a reindex (admin). Optionally restrict to a channel. Changed files are picked up automatically, so this is rarely needed. force=true re-embeds EVERY file in the channel (paid embedder calls for the whole corpus); use it only after changing the embedder or chunking, never to |
remember | read | Persist a durable, curated memory entry worth recalling in future sessions \u2014 a decision, preference, convention, or hard-won fact \u2014 NOT ephemeral scratch or transient task state. Writes a markdown entry into the current project |

reviewer | read | Review pull requests |
search_all | read | Unified search across all configured channels (memory + skill + observation + remote). Returns merged top-K. |
search_memory | read | Search across local memory files (curated user memory). Returns top-K results. |

search_skill | read | Search across skill bodies (section-level). Returns top-K matching sections. |
stats | read | Return corpus stats: total chunks, by channel, last index time, embedder info. |
status | read | Health check: is the captain-memo worker up and healthy? Returns the worker |
todo_add | write | File HOMEWORK on this captain: an idea or a task for later — not for now. Kept per captain (every AI session on this machine shares the list; Claude Code sessions see the open items at start, other tools call todo_list), with a lifecycle open → claimed → done. Use it when the user says |
todo_claim | read | Take a homework item before starting it, so every other session on this machine sees it as claimed by you. Advisory, not a lock: re-claiming is allowed (it just updates who has it). |
todo_done | destructive | Close a homework item, with a one-line note of what was done (or why it was dropped). Done items stay listable for a week. |
todo_list | read | The homework on this captain: open items (default), done ones (kept a week), or all \u2014 each with number, text, topics, who filed it, who claimed it, and its due time (UTC) when it has one. Read it at the start of a session when you have nothing else to do, or when the user asks |
todo_unclaim | read | Hand back YOUR claim on a homework item without closing it: use it when you claimed an item only to look at it, or cannot do it now. todo_claim has no other undo and todo_done closes the item. Refused for an item another session holds, an item nobody holds. |

Questions
What is the captain-memo MCP server?
Local, cross-AI memory for coding agents: Claude Code, Codex, Gemini, Antigravity, Cursor, Kimi & more share one private corpus. Hybrid search, auto-injected context, a shared skill library, a work board so sessions don't collide, and homework for ideas parked mid-task. No-API-key summarizers; runs
What tools does captain-memo expose?
31 in total: 28 read-only, 2 that write, and 1 that can delete or overwrite (todo_done). Every one is listed on this page with its risk.
Is captain-memo safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (47/100) and found 3 critical or high issues in the source. Each one is listed on this page with the file and line it is on. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does captain-memo need?
It reads ANTHROPIC_API_KEY, API_KEY, CAPTAIN_MEMO_EMBEDDER_API_KEY, CAPTAIN_MEMO_EMBEDDER_MAX_TOKENS, CAPTAIN_MEMO_EMBEDDER_WASTE_LIMIT_TOKENS, CAPTAIN_MEMO_HOOK_BUDGET_TOKENS, CAPTAIN_MEMO_OPENAI_API_KEY, CAPTAIN_MEMO_RARE_TOKEN_BOOST, CAPTAIN_MEMO_SHOW_READ_TOKENS, CAPTAIN_MEMO_SHOW_WORK_TOKENS, CAPTAIN_MEMO_VOYAGE_API_KEY and CAPTAIN_MEMO_WORKER_AUTH from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does captain-memo run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as captain-memo at 0.57.5.
How current is this page?
The grade is for one exact copy of the source (2e18e5e208a1), read on 2026-10-11. The repository is watched and re-audited when it changes.
