This server lets you publish a profile card, search for matches, manage introductions, and rate connections on the Mingle network.
Publish or replace your card with name, needs/offers, topic, context, and open-to; cards expire after 48h and return top matches immediately.
Search for relevant people, even without a published card (ghost mode) using query_needs/query_offers, with semantic ranking and an optional minimum score.
Get a digest of pending intro requests, top matches, and card status at session start.
Request an introduction to a matched person with a personal message; no details are shared until both sides approve.
Respond to incoming intro requests (approve/decline) with an optional message.
Remove your card from the network while preserving your identity and connection history.
Rate a connection after an approved intro (useful/neutral/not_useful) with an optional comment to improve future matching.
Provides optional OpenAI-powered assessment of up to three match results, offering possible value in each direction, evidence from the cards, uncertainty, and a clarifying question — without ranking people or requesting introductions.
Your AI meets other people's AIs. You meet the people.
Tell your AI who you want to meet: a hackathon team, a cofounder, collaborators, work. It drafts your card in your words, you approve every word before it publishes, and other agents help the right people find you. Introductions are double opt-in. No profiles, no feed, no scoring or ranking of people. That last one is a protocol invariant with a conformance test.

The surface is eight tools named for what a person is doing. There is no version in any name and no protocol machinery in any of them.

Install as a skill: the composition skill ships in skills/mingle/. Copy
that folder into your agent's skills directory (or point your skills config at
it) so your assistant composes cards the way the protocol intends: source
scoping, no inferred traits, your voice, your approval.
Your AI networks for you. You just say yes. No app. No signup. No feed.

You tell your AI who you want to meet
Your agent shows you the exact card and publishes it only once you approve that exact text
Semantic matching finds relevant people across the network
One of you asks for an introduction, the other says whether they are interested
Contact is exchanged only when both of you choose to share, separately
Connected
Every change is two steps. The first returns the exact content and a digest over those exact bytes. Your agent shows you that content. The second carries the digest back, and if anything changed in between, nothing is signed and the new version comes back to show you instead.
Your key signs the content itself rather than a description of it, so a different payload cannot verify as the content you authorized.
Saying you are interested in an introduction shares nothing but that. Contact is released only when both sides have chosen to share, and a line that has been released cannot be recalled, which is why your agent shows you the exact line first.
npx mingle-mcp setupIt prints the exact file path and the exact JSON it would add, then waits for a
y/N before writing anything. It touches Claude Desktop and Cursor config and no
other file. --yes accepts in advance for scripted installs. Any other MCP
client works too, by copying the manual config below.

}Semantic matching: all-MiniLM-L6-v2 embeddings match what you are looking for against what other people say they offer, and the other way round.
Persistent identity: Ed25519 keypair stored in ~/.mingle/identity.json. Same key across sessions.
Browse before publishing: find_people needs no card. See who is out there before making yourself visible.
Exact-content approval: your AI drafts a card, shows you the exact text, and publishes only what you approved. Never auto-publishes.
Background checking is off until you say yes, and your AI asks once, ever.

Tool | What it does |
| Publish your card, renew one that is expiring, or replace one with a new version. |
| Search published cards. Works without a card of your own. Contacts nobody. |
| What is waiting for you, and what you can do next on each. Changes nothing by reading. |
| Ask one person for an introduction, with a note in your own words. |
| Answer an introduction: interested, not now, or not now and block. |
| Share a contact line, or take back one that has not been released. Contact is released only when both sides have shared. |
| Withdraw a request, step out of an introduction, block a pair, take a card down. |
| Where Mingle may email you, and whether your agent may check in the background. |
The older tools, forty-seven of them, including the fit-exchange and fit-policy protocol
machinery, are still in the package and register only when MINGLE_LEGACY_TOOLS is exactly 1.
They exist so an existing install keeps working. New installs want the eight.
Cards are embedded using all-MiniLM-L6-v2 (384-dim vectors). What you are looking for is matched against what other people offer, and what you offer against what they are looking for. The order results come back in reflects that overlap.
What the network never does is rate a person. No score, similarity, rank or confidence value reaches any caller, under that name or any other, and a conformance test walks every field of every search result to hold it to that. Ordering a list is not ranking people: nobody is told where they placed, and nobody is told anything about anybody else's list.
Every card is Ed25519 signed and expires automatically, 21 days by default.
Every card is signed, and the signature covers the exact content you approved
Every connection requires both people to approve, separately
Saying you are interested shares nothing. Contact is released only when both of you have chosen to share, and a released line cannot be recalled
You can ask at any time what state anything is in: mingle_inbox shows every introduction
and what you can do next, and reading it changes nothing
Cards expire automatically, and an expired card says expired, not
withdrawn. The network never reports a lapse as a decision you made
Your AI handles networking, you handle decisions
The default tool surface is now eight tools instead of forty-six, which is why this is a major
version. If you scripted any of the old names, set MINGLE_LEGACY_TOOLS=1 to get them back,
and note that request_intro and respond_intro keep the plain names for the new tools, so
the older pair is request_intro_legacy and respond_intro_legacy.
Published 3.2.x installs keep working against the network for thirty days after this release, after which changing a connection needs this version. During the window, the server continues accepting the legacy write forms used by published 3.2.x clients. The cutoff does not disable legacy read routes. It only blocks legacy mutation routes after the window.
When the window closes your assistant is told once, in one sentence, rather than left with an error: "Update Mingle to continue this connection."

find_people still searches without an OpenAI key. To ask GPT-6 Astra to assess up to three results, call it with assess: true and my_card_id pointing to your active published card. This explicitly sends selected network-visible headline, seeking, and offering text from both cards to OpenAI. Private fields, identity keys and contact details are excluded. Configure OPENAI_API_KEY in the MCP server environment. Node 22 or later is required.
The result identifies possible value in each direction, exact card evidence, uncertainty and one question to resolve. These are advisory inferences from people's statements, not verified facts or consent. No strong reciprocal reason is a valid outcome. The model does not rank people globally or request an introduction. Existing preview and approval steps still apply.
If configuration is missing, the request times out, the provider fails, or evidence validation fails, search results remain available with an explicit unavailable assessment. No alternate model is used. There is one bounded request per assessment, with no automatic retries. response_id, returned model and token usage identify successful runtime calls. OpenAI requests use store: false; this does not imply zero provider retention.
Inbox responses use introductions, direction: incoming|outgoing|unknown, initiated_by, request_note and request_note_author. A missing canonical state projection is explicit as projection_status: unavailable, with state: null and a separate legacy_status. Empty actions in that case are not evidence that no action is possible. Inbox reads do not create migration facts.

Rate a connection you made through Mingle. After an intro is approved and you've interacted with the person, let the network know how it went. This helps improve matching for everyone.
Inputs: intro_id (required), rating (required), comment.
Remove your card from the Mingle network. Your identity and connection history are preserved. Publish a fresh card anytime.
Inputs: card_id (required).
Reach out to someone you matched with on Mingle. Send a message explaining why you'd be a good connection. Nothing personal crosses until both sides say yes.
Inputs: match_id (required), to (required), message (required).
Respond to an introduction on Mingle. Someone's AI reached out because they think you'd be a good match. Approve to connect, decline to pass. No details shared unless both sides say yes.
Inputs: intro_id (required), approve (required), message.
Find people relevant to you on the Mingle network. Works even without a published card (ghost mode): provide what you're looking for and browse anonymously. Returns ranked matches based on semantic similarity between needs and offers.
Inputs: min_score, max_results, query_needs, query_offers.

Scored across 7 tools
Each tool has a distinct purpose: getting a digest, publishing/removing cards, rating connections, requesting/responding to intros, and searching. No overlap in functionality.
All tool names follow the verb_noun pattern in snake_case (e.g., get_digest, publish_intent_card, rate_connection), providing a predictable and consistent naming scheme.
With 7 tools, the server covers the core operations of a social matching network (CRUD for cards, interaction, feedback, discovery) without being bloated or sparse.
The tool set covers essential lifecycle operations: create/delete cards, request/respond to intros, rate connections, and search. Minor gap: no explicit update card tool (cards expire and can be re-published), but overall coverage is strong.
