Overview

Transfa provides ephemeral file transfer for AI agents, shell scripts, and CI/CD pipelines. It uploads local files and returns agent and human links, checksums, and expiration details. Use it when workflows need temporary artifact sharing, download controls, or run-level provenance.

Use cases

โ€ขUpload build artifacts from CI/CD workflows
โ€ขShare large models, archives, or datasets with expiring links
โ€ขTrack files associated with an agent run
โ€ขInspect upload metadata and checksum information
โ€ขDelete uploaded files before expiration

Key features

โ€ขUpload local files up to the service plan limit
โ€ขReturn direct and human-facing download links
โ€ขVerify files with SHA-256 checksums
โ€ขEnforce TTLs, passwords, and download limits
โ€ขRecord run, step, consumer, and intent provenance
โ€ขList, inspect, and delete uploads

Capabilities & Tool Schemas (5) ~126 tokensApproximate context cost of this serverโ€™s tool schemas (~4 chars/token), before any tool is called.

Inspect callable tools, capabilities, and parameters exposed to AI agents by Transfa.

upload

Upload a file from the local filesystem. Returns `agent_link` (direct URL), `human_link` (share page), and `sha256`. Accepts `run_id`, `step`, `consumer`, `intent` for provenance.

file_info

Get metadata about an upload โ€” filename, size, SHA-256, expiry, download count, provenance fields.

list_uploads

List recent uploads (requires API key).

delete_upload

Delete an upload immediately.

run_artifacts

Get all files uploaded under a `run_id` โ€” the full provenance manifest for a pipeline run or agent session.

Documentation Overview

transfa

Dead-simple file sharing for developers and AI agents.
Upload with one command. Share with a link. No account required.

npm version npm downloads node version MIT License Hosted service


Code
$ tf upload model.gguf
โœ“ Uploaded  model.gguf  (4.2 GB)  โ†’  https://transfa.sh/f/xK9mRp
  SHA-256    a3f8c2...d91b
  Expires    in 7 days

Why transfa?

Most file-sharing tools are built for humans clicking through UIs. transfa is built for the terminal โ€” designed to be called from shell scripts, CI pipelines, and AI agents (Claude, GPT, Cursor, etc.) that need to move files without friction.

  • No signup required โ€” just install and upload
  • Any format, any size โ€” up to 100 GB; ML models, archives, binaries, code, media
  • Built for agents โ€” JSON API, SHA-256 checksums, idempotent uploads
  • Password protection, download limits, TTL โ€” full control over every link
  • 100+ formats detected โ€” MIME type auto-detection including .gguf, .safetensors, .parquet, .ipynb, and more

Install

Node.js / CLI

Terminal
npm install -g transfa

Python SDK

Terminal
pip install transfa

MCP server (Claude, Cursor, any MCP-compatible agent)

Terminal
npx -y transfa-mcp

Or use the raw install script:

Terminal
curl -fsSL https://transfa.sh/install | sh

Quick start

bash
# Upload a file (no account needed)
tf upload photo.jpg

# Upload with custom TTL and password
tf upload secret.zip --ttl 24h --password hunter2

# Upload and pipe the URL to clipboard
tf upload bundle.tar.gz | grep url | awk '{print $2}' | pbcopy

# Download a file
tf download https://transfa.sh/f/xK9mRp

# List your uploads
tf list

# Delete an upload
tf delete xK9mRp

GitHub Actions

Upload build artifacts, coverage reports, and any CI output straight from your workflow:

yaml
- uses: colapsis/transfa-action@v1
  id: upload
  with:
    file: ./dist/report.pdf
    api-key: ${{ secrets.TRANSFA_API_KEY }}

- run: echo "${{ steps.upload.outputs.agent-link }}" >> $GITHUB_STEP_SUMMARY

All five outputs are available after the step: id, agent-link, human-link, sha256, expires-at.

See colapsis/transfa-action for the full input reference and more examples (password-protected links, self-hosted instances, single-download limits).


API

transfa is fully REST. Every operation the CLI does, you can do with curl or any HTTP client.

MCP server (Claude, Cursor, and any MCP-compatible agent)

transfa ships an MCP server that lets Claude, Cursor, and any MCP-compatible agent upload and share files autonomously โ€” no shell commands, no infrastructure setup.

Terminal
npx -y transfa-mcp

Claude Desktop config

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

config.json
{
  "mcpServers": {
    "transfa": {
      "command": "npx",
      "args": ["-y", "transfa-mcp"],
      "env": {
        "TRANSFA_API_KEY": "your-api-key"
      }
    }
  }
}

The API key is optional โ€” the server works in guest mode without one (10 MB / 24h limit).

Available MCP tools

ToolDescription
uploadUpload a file from the local filesystem. Returns agent_link (direct URL), human_link (share page), and sha256. Accepts run_id, step, consumer, intent for provenance.
file_infoGet metadata about an upload โ€” filename, size, SHA-256, expiry, download count, provenance fields.
list_uploadsList recent uploads (requires API key).
delete_uploadDelete an upload immediately.
run_artifactsGet all files uploaded under a run_id โ€” the full provenance manifest for a pipeline run or agent session.

Example agent workflow

When Claude has transfa as an MCP tool, it can:

  1. Generate a report โ†’ call upload โ†’ get a link โ†’ paste the link in the conversation
  2. Pass a file to another agent by sharing the agent_link
  3. Clean up with delete_upload when done

Python SDK

server.ts
import transfa

# Upload
result = transfa.upload("model.pt", ttl="24h", run_id="run-42", artifact=True)
print(result.url, result.sha256)

# Download (SHA-256 verified)
transfa.download(result.id, output="model.pt")

# Provenance manifest for a run
manifest = transfa.run_artifacts("run-42")

# Async
async with transfa.AsyncClient() as client:
    result = await client.upload("model.pt")

See python/README.md for the full API reference.


Use with AI agents (script/subprocess)

transfa is also designed to be called from shell scripts, CI pipelines, and agents that prefer subprocess calls:

server.ts
import subprocess, json

result = subprocess.run(
    ["tf", "upload", "output.csv"],
    capture_output=True, text=True
)
data = json.loads(result.stdout)
print(data["url"])  # https://transfa.sh/f/xK9mRp

Or use the REST API directly โ€” no SDKs, no auth flows, just HTTP.


Self-hosting

bash
git clone https://github.com/colapsis/transfa.git
cd transfa
cp .env.example .env          # fill in your keys
npm install --prefix server
npm install --prefix cli
npm run build --prefix frontend
pm2 start ecosystem.config.cjs

Requirements: Node.js 18+, nginx (for SSL/proxy)

See nginx/transfa.conf for a production-ready nginx config.
