Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Secure, expiring artifact storage and handoff for AI agents.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
AISPACE_KEY, AISPACE_URL, AISPACE_ALLOWED_ROOTSValues marked secret are keys to your account. Never share them or paste them into a chat.

aispace
Secure temporary file sharing for AI agents and humans.
A scriptable CLI with expiring links, predictable JSON, and optional local age encryption.
Website · Documentation
aispace.sh is a bot-friendly file drop for outputs that are too large, structured, or temporary for chat. The open-source client is deliberately easy to automate: one binary, stable exit codes, streaming uploads, and share URLs printed on a predictable final line.
Sealed transfers, agent identities, device pairing, and adaptive durable-first intent are experimental surfaces. Ordinary uploads and durable R2 storage continue to work alongside them.
The hosted service is operated separately. This repository contains the client, agent skill, and integration examples—not the server, billing system, deployment configuration, or customer data.
Install the latest release:
curl -fsSL https://aispace.sh/install.sh | sh
Authenticate with a key created in the aispace dashboard, then store a file:
aispace login --key ask_...
aispace upload report.pdf --json
On a Pro account, add a separately expiring public handoff:
aispace upload report.pdf --link --link-expires 1h --max-downloads 1
The URL is printed last on its own line, making it easy for an agent or shell script to capture. Add --json for a stable machine-readable response. An abridged response looks like:
{"file":{"id":"...","name":"report.pdf"},"link":{"url":"https://aispace.sh/d/...","expires_at":1757003600}}
Other installation channels:
npm install -g @aispace-sh/cli
brew install aispace-sh/tap/aispace go install github.com/aispace-sh/aispace-client@latest
Pin the shell installer with AISPACE_VERSION=v1.2.3. Release binaries support macOS, Linux, and Windows on amd64 and arm64. The shell installer supports macOS and Linux; use npm on Windows.

The repository includes a reusable Codex-compatible skill. Clone the repository and link the skill into your personal Codex skills directory:
git clone https://github.com/aispace-sh/aispace-client.git
mkdir -p ~/.codex/skills ln -s "$PWD/aispace-client/skills/aispace" ~/.codex/skills/aispace
Restart Codex, then ask it to use aispace when it needs to hand you a report, archive, image, or other generated artifact. The skill defaults to account-private storage unless you request a public link, prefers short expirations, and treats encryption identities as credentials.
The native CLI also exposes ten typed MCP tools over local stdio. Create a separately scoped bot key in the dashboard, export it in the environment that launches Codex, and add:
[mcp_servers.aispace]
command = "aispace" args = ["mcp", "serve"] env_vars = ["AISPACE_KEY", "AISPACE_URL", "AISPACE_ALLOWED_ROOTS"] startup_timeout_sec = 10 tool_timeout_sec = 120 default_tools_approval_mode = "writes"
[mcp_servers.aispace.tools.aispace_create_link] approval_mode = "prompt"
[mcp_servers.aispace.tools.aispace_revoke_link] approval_mode = "prompt"
[mcp_servers.aispace.tools.aispace_delete_file] approval_mode = "prompt"
Run codex mcp list to verify the connection. The ChatGPT desktop app, Codex CLI, and Codex IDE extension on the same host share this configuration. Keep the key in a secret store or injected environment; never put its expanded value in a committed project file or command argument. See docs/CLI.md for Claude Code and generic-host examples.
For custom agent runtimes, docs/LLM_USAGE.md includes a system-prompt snippet, OpenAI/Anthropic-compatible tool schemas, and a reference Python handler. See examples for runnable shell, CI, and encrypted-handoff recipes.

Follow docs/SECURE_HANDOFFS.md for sealed bundles, trusted agent inboxes, device pairing, adaptive R2 fallback, and recovery. The complete command reference is in docs/CLI.md; the HTTP contract is in docs/API.md.
upload accepts --name, --expires, --content-type, --sha256, --link, --link-expires, --max-downloads, --private, --shared, --encrypt, --recipient, and --identity-out. Uploads stream from disk. Encrypted uploads use age X25519 locally and store ciphertext as .age; the secret identity is never sent to the API.
transfer create uses aispace-sealed-v1: AES-256-GCM authenticated chunks and an encrypted manifest support multiple files, ranged retry, and a verified receipt. transfer receive accepts the secret from its prompt, --token-file, or AISPACE_TRANSFER_TOKEN; avoid putting a full fragment link or token in a process argument on shared systems.
transfer create --json omits bearer links and tokens unless --include-secret is explicit, and secret-inclusive JSON must be redirected rather than written to a terminal. handoff encode likewise accepts the protected prompt, --token-file, or AISPACE_TRANSFER_TOKEN.
With --json, errors also remain structured and are written to stderr. upload --link --json returns {"file": File, "link": ShareLink}; encrypted uploads add an "encryption" object.
Precedence: flag > environment > config file > default.
| Setting | Flag | Env | File key | Default |
|---|---|---|---|---|
| API key | --key | AISPACE_KEY | key | — |
| Server | --url | AISPACE_URL | url | https://aispace.sh |
AISPACE_AGE_IDENTITY supplies a decryption identity when decrypt --identity-file is omitted. It is deliberately not accepted as a command-line value.
Config file: $XDG_CONFIG_HOME/aispace/config.json (default ~/.config/aispace/config.json), written with mode 0600. A warning is printed if the file is readable by others. AISPACE_CONFIG overrides the path.
Durations (--expires, --link-expires) accept Go syntax plus a d suffix: 30m, 24h, 7d, 1d12h, or a bare number of seconds. Omitting them uses the server defaults (7 days for files, 1 hour for Pro public links).
File visibility controls authenticated key access. A public link is a separate capability: creating one requires a Pro account and makes that one file available to anyone holding the URL.
| File mode | Who can access it? | File lifetime | Public-link lifetime | Download cap | Exposure if access leaks |
|---|---|---|---|---|---|
private | Uploading key only | 7 days by default; maximum 7 days on Free or 30 days on Pro | None | Account monthly limit | Private files belonging to that key, until deletion or expiry |
account | Every active key on the account | 7 days by default; maximum 7 days on Free or 30 days on Pro | None | Account monthly limit | Account-shared files, until deletion or expiry |
private + public link | Uploading key and anyone with the URL | Maximum 30 days because links require Pro | 1 hour by default; maximum 30 days and never beyond file expiry | Optional per-link cap | Only the linked file, until link expiry, revocation, exhaustion, file deletion, or file expiry |
account + public link | Account keys and anyone with the URL | Maximum 30 days because links require Pro | 1 hour by default; maximum 30 days and never beyond file expiry | Optional per-link cap | URL access ends with the link; account keys retain access until file deletion or expiry |
| Client-encrypted file | Visibility controls ciphertext access; only age identity holders can decrypt it | Same limits as the selected file mode | Same Pro-only limits when a link is created | Optional per-link cap | Plaintext exposure requires both the ciphertext and the age identity |
Available duration syntax includes 30s, 15m, 1h, 36h, and 7d.
A file becomes unavailable when its file lifetime ends. A link can end sooner because it expired, was revoked, or reached its download cap. Deleting the file immediately ends authenticated key access and every associated public link.
