Instaffo Server

An MCP server that gives an AI assistant access to your own Instaffo candidate account, authenticated with your own browser session. Personal job-search tooling. Runs fully local.

Instaffo is a two-sided recruiting marketplace (candidates are matched with companies). This server exposes the candidate side: read your profile and job suggestions, read conversations, and perform reversible write actions, from an MCP client.

How it works

Instaffo has no public candidate API, so the server authenticates with a real logged-in session. Its candidate web app talks to a clean JSON API under app.instaffo.com/candidate/api/v1/*, authenticated purely by the session cookie (no bearer token). So the server is a thin cookie-authenticated httpx client, not a scraper. A browser (via patchright) is used only once, to mint the session at login.

MCP client ── stdio ──> instaffo-mcp-server ──cookie──> app.instaffo.com JSON API
                              │
                     storage-state.json  (cookies, written 0600, git-ignored)
                              ▲
                     instaffo-mcp --login  (one-time browser sign-in)

Setup

uv sync
uv run patchright install chromium     # one-time, for login only
uv run instaffo-mcp --login            # opens a browser; sign in once
uv run instaffo-mcp --auth-status      # confirm the session is stored

Register it with your MCP client (stdio):

{
  "command": "uv",
  "args": ["run", "--directory", "/path/to/instaffo-mcp-server", "instaffo-mcp"]
}

Tools

Reads (no side effects):

Tool	What it returns
instaffo_whoami	your identity (name, email, job title)
instaffo_get_profile	your profile: seniority, location, skills, CV summary
instaffo_list_job_suggestions	your current matches, with counters
instaffo_get_job_suggestion	one role in full: description, requirements, salary, screening questions
instaffo_list_conversations	company requests (inbound interest) and your applications
instaffo_auth_status	is a session present (--deep validates it live)

Writes (every write tool takes confirm; without it you get a preview and nothing changes):

Tool	Effect	Endpoint
instaffo_save_job	bookmark a suggestion (reversible)	POST .../job_suggestions/{uuid}/favorite
instaffo_unsave_job	remove a bookmark	DELETE .../job_suggestions/{uuid}/favorite
instaffo_set_skill_experience	set your years per skill on your profile	POST .../experience_durations/bulk_save

All endpoints above are verified against the live API.

Supervised, on purpose: apply and message

Two actions are intentionally not implemented as fire-and-forget tools: applying to a job, and messaging a recruiter.

Applying is not one request. It is a multi-step wizard that writes lasting self-representations to your real profile before it submits:

1. a skill self-assessment (year sliders per required skill, e.g. 0-5), which auto-saves to your profile via experience_durations/bulk_save,
2. your salary expectation (pre-filled from your profile),
3. an "AI tools you use" and "AI skills" multi-select,
4. a final submit that creates the application and opens a chat with the recruiter.

Because those are real, outward-facing choices about how you present yourself, and the final submit endpoint only appears once the whole flow is completed, the apply and message tools are left for a supervised session where the account owner approves the inputs. They are not built against a guessed endpoint. The observed sub-steps and wizard shape are recorded here so that session is quick.

Commands

instaffo-mcp                 # run the MCP server (stdio)
instaffo-mcp --login         # headed manual login, persist the session
instaffo-mcp --capture       # record app API traffic to a JSONL (diagnostics)
instaffo-mcp --auth-status [--deep]

Security and privacy

• Session material (profile/, storage-state.json, captures/, .env) lives under ~/.instaffo-mcp, is written 0600, and is git-ignored. It is never committed.
• Write tools are confirm-gated and only touch reversible surfaces.
• This is a personal, local tool for your own account. It stores no one else's data and talks only to Instaffo with your own session.

Prior art

The session-capture and browser patterns are adapted in spirit from stickerdaniel/linkedin-mcp-server (Apache-2.0), which authenticates a personal LinkedIn session the same way.
