UltraMemory vs Contextium MCP Server

list

List all resources of a given type in a workspace — the fast way to see what already exists before you act. Returns lightweight summaries (IDs, names, key fields), not full content: use `get` for one resource's full detail, or `search` to find resources by text or tag. Set `type` to choose what to list — workspaces, libraries (context libraries), agents, skills, files (pass libraryId), workflows, tags, file_tags (pass fileId), workspace_status, or members (with roles + activity). Uses your active workspace when workspaceId is omitted.

get

Get full details of a resource by ID. Use workspace_activity for recent activity logs. Use activity_archive to read a specific month's archived logs by YYYY-MM (e.g. 2025-02). Use list_activity_archives to see which months have archives. Use workflow_activity for the activity digest since a workflow's last session. Use entity_activity for recent activity on a specific file or entity.

create

Create a new resource in a workspace. Set `type` to what you're creating: "file" (needs libraryId + title + complete content), "library" (a context library — needs name), or "agent" / "skill" / "workflow" (need name; a workflow can bundle projectIds, agentIds, skillIds, and tagIds). Always provide full, real content for files — never empty or placeholder. File linking: to link to another file in the SAME workspace, put //<fileId> inline in the content — use the target file's UUID (from search/list/get results), not its title. The link renders as the target's title and is indexed automatically on save; the target gains a backlink with no extra step. Add a link only where the text genuinely references an existing file; never invent //<id> for a file that does not exist (it becomes a dangling link). Use get({ type: "file_links", id }) to inspect a file's links and backlinks.

update

Update an existing resource in place by ID — edit a file's title, path, content, or status, or rename/reconfigure an agent, skill, workflow, or project. Only the fields you pass are changed; for files, a new version is created automatically so history is preserved. Set `type` to the resource kind and `id` to its UUID (from list/search/get). File linking (type=file): to link to another file in the SAME workspace, put //<fileId> inline in the content — use the target's UUID (from search/list/get results), not its title. The link renders as the target's title and is re-indexed on save; backlinks are automatic. To add a backlink to file B, add //<B-id> to this file's content. Remove a link by deleting its //<id> token. Only link to files that exist. Use get({ type: "file_links", id }) to inspect links and backlinks.

delete

Delete a resource (moves to trash, restorable). type: file | skill | workflow

search

Find files in a workspace when you don't know their exact ID. Pick a `mode`: "text" runs a full-text search over file contents and titles; "tags" returns files carrying ALL of the given tagIds (AND logic); "files" matches by partial file name/title. Reach for search before `get` when you only know roughly what you want; use `list` with type=files instead when you just need everything in a library. Optionally narrow to one library with libraryId.

suggest_libraries

Suggest existing context libraries that look relevant to a workflow you are about to create, ranked by keyword overlap between the workflow name/description and each library's name/description. Call this BEFORE create_workflow (or create type=workflow) so you can present the matches to the user and let them choose which to attach via projectIds. Nothing is auto-attached — these are suggestions only. Returns [] when no libraries score above zero.

load_workflow

Load complete workflow context — agents, skills, files, and libraries. Use this to initialise a full workflow session.

manage_relationship

Manage relationships: add/remove skills on agents (one at a time, or many in one call with apply_bulk/remove_bulk + skillIds), add/remove inline tags on files, and share/unshare a private workflow with an individual workspace member. For type=tag this EDITS THE FILE CONTENT — it writes (or deletes) a #<value> token in the file body, which is the source of truth for a file's tags; the tag is auto-created if new. (Equivalent to updating the file content yourself.) For type=workflow_member, add is an upsert (re-adding an existing member updates their role).

marketplace

Browse, inspect, and install shared skills, agents, and MCP servers from the Contextium Marketplace. Set `action`: "search" to browse listings (optionally filter by itemType skill/agent/mcp_server, category, or query); "get" for a listing's full details by slug; "install" to add a listing to a workspace by slug. Typically search first to find a slug, then get or install with it.

project

DEPRECATED — phases are now DB-backed. Use list_phases (replaces get_next_phase), update_phase_status(phaseId, "done") (replaces mark_phase_complete), and load_workflow (replaces load_session/close_session).

figma_sync

Manage Figma connector integrations — list connected files or trigger a sync to pull design tokens, components, and page structure into your Contextium libraries.
