  • validate_seedwrite actionFree

    Runs a draft seed document through the exact parser the Calaf app imports with. Pass the entire JSON document as a string. Returns per-section counts and the precise issue list (path, severity, message): severity "error" means nothing imports; "dropped" means that row or field is discarded and the rest lands. Fix the issues and validate again until clean before delivering the file to the user.

What the publisher says

From the Calaf Seed Tools repository's README, as published. We do not edit it. Read it on GitHub

Calaf MCP Server

Connect Claude, ChatGPT, or any MCP-capable assistant to Calaf — the MBA recruiting manager. Your assistant researches target firms at whatever depth you ask, writes and validates structured "seeds," and files them into your recruiting book. People it proposes always arrive staged for your review — nothing enters your network behind your back.

Two servers, one product. ai.calaf/calaf connects to your account (OAuth). ai.calaf/seeds is the no-auth authoring loop — the format and the validator, usable by anyone, no Calaf account required.

Things to ask once connected

  • "Research 30 lower-middle-market PE funds that hire MBA associates, validate the seed, and import it into my book."
  • "Read Calaf's seed format, then turn the target list from this conversation into a seed and validate it until it's clean."
  • "List my Calaf workspaces and import these interview prep questions into the consulting one."
  • "I just got off a superday with Evercore — log it, move my application, and set a follow-up task for Friday."
  • "Create a workspace for lower-middle-market PE, add my ten targets, and draft outreach templates."
  • "Research the partners at my five priority funds and add them to my book" — they'll land as a batch waiting for your review in Calaf, never as silent rows.

Installation

claude.ai (web / desktop)

  1. Open Settings → Connectors (claude.ai/settings/connectors)
  2. Add custom connector → name it Calaf, URL https://calaf.ai/api/mcp-account, leave Client ID/Secret empty
  3. Click Connect → you'll land on Calaf's consent screen — sign in and approve

Requires a paid claude.ai plan (custom connectors are Pro and above).

Claude Code

claude mcp add --transport http calaf https://calaf.ai/api/mcp-account

Any other MCP client

Add a remote (Streamable HTTP) server at https://calaf.ai/api/mcp-account. The OAuth flow is standard: dynamic client registration + PKCE; your client discovers the authorization server via RFC 9728 protected-resource metadata.

No MCP client at all

The copy-paste loop works with every assistant: Calaf's Guide and Settings carry a one-paste prompt that teaches any AI the seed format; the assistant can self-check via the open validator API (below) and you import the file at Settings → Workspace → Seeds.

Tools — ai.calaf/calaf (account server)

getseedformat · read-only

Returns the complete calafseed: 1 specification (markdown) — sections, ceilings, parser behavior, and the rules an assistant should follow when authoring a seed. Read it before authoring; then check drafts with validateseed.

No parameters.

validate_seed · read-only

Runs a draft seed document through the exact parser the Calaf app imports with and returns the verdict: per-section counts plus the precise issue list. Issue severity error means nothing would import; dropped means that row or field is discarded and the rest lands. Fix and re-validate until clean before delivering the file.
