In-depth architectural comparison of the Md Log MCP and 1Claw Vault MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Md Log MCP
Security · Local stdio
Quality: 56/100 (Good) | Auth: No auth required
1Claw Vault
Security · Local stdio
Quality: 56/100 (Good) | Auth: API Key required
Verdict Summary: Choose Md Log MCP if you need specialized Security tools running via a local process. Choose 1Claw Vault if your workspace requires Security integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Md Log MCP when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
You have access to required keys: ONECLAW_AGENT_API_KEY, ONECLAW_AGENT_TOKEN, ONECLAW_VAULT_ID, ONECLAW_LOCAL_ONLY, ONECLAW_LOCAL_VAULT, ONECLAW_DAEMON_SOCKET, MCP_TRANSPORT, PORT.
Upload one image (reserve → presigned PUT → complete) and return an `asset://<key>` reference to embed as ``. Provide the image as **either** `data_base64` (inline base64) **or** `file_path` (a local file the server reads) — exactly one; with `file_path`, `filename` defaults to…
append_to_markdown
Append to an existing file with optimistic concurrency (GET current → concat → conditional PUT with `base_version_no`). Auto-retries once on conflict, then surfaces `CONFLICT`. Accepts `commit_message` — a recommended 1-2 line change summary shown in the version history.
update_markdown
Replace a file's content. Pass `expected_version` for optimistic concurrency (mismatch → `CONFLICT`); omit it to force LWW. Accepts `commit_message` — a recommended 1-2 line change summary shown in the version history.
get_markdown
Read a file's content by path (materializes inline content or a presigned content URL for large docs). Pass `version` (a `version_no` from `list_versions`) to read an old immutable version.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Md Log MCP is categorized under Security and uses a local stdio subprocess. In contrast, 1Claw Vault belongs to Security using local stdio subprocess. Select Md Log MCP when you need capabilities focused on security and 1Claw Vault when you require tools for security.
List a file's immutable version history, newest first (`version_no`, `commit_message`, author, `registered_at`, size).
delete_markdown
Soft-delete a file. Requires `confirm:true` (otherwise `VALIDATION`); resolves the path to a document key first.
create_folder
mkdir -p` — create every missing segment; already-existing folders count as success.
list_folders
Return the full folder tree.
list_files
List the documents and immediate subfolders inside a folder path.
search_markdown
Search by TITLE (substring) + BODY full-text (current versions; whole-word match, ranked, body hits include a snippet).
move_markdown
Move and/or rename a `.md` by path (`from_path` → `to_path`); destination folders auto-created; the document KEEPS its key, so version history and reviewers' annotations survive.
move_folder
Move a folder (whole subtree) under a new parent (`new_parent_path` empty/omitted = root); parent auto-created; cyclic moves rejected server-side.

1Claw Vault Tools (37)
list_secrets
List all secrets (metadata only — never values)
get_secret
Fetch the decrypted value of a secret by path. Accepts optional `client_share` for MPC vaults.
put_secret
Create or update a secret (creates a new version). Response includes `client_share` when the vault has MPC enabled.
delete_secret
Soft-delete a secret at a path
describe_secret
Get metadata without fetching the value
rotate_and_store
Store a new value for an existing secret and return the version
rotate_generate
Server-side secret rotation with generated value (length, charset configurable)
list_versions
List all versions of a secret (version numbers, dates, disabled status)
get_env_bundle
Fetch an env_bundle secret and parse it as KEY=VALUE JSON
list_child_agents
Child agents under a parent (own key/memory/policy, subset of the parent's access; vault ≥ 0.61.30)
resolve_env
Resolve environment variables for a vault and environment (returns the final KEY=VALUE set with precedence applied). When the agent has `env_auto_resolve: true`, omit `environment` and the server uses the agent's tagged environment from the JWT.
create_vault
Create a new vault (auto-shared with the agent's human creator)
