MCP Server for Z.AI - A Model Context Protocol server that provides AI capabilities
Nothing to run from here
Contribution Exchange is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Contribution Exchange MCP: domain discovery, policies, preflight, proposals, and signals.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http contribution-exchange-mcp https://signalaf.com/api/exchange/mcp
# 2 — ask your agent for something these tools do
# exchange_discover_domain, exchange_get_policy, exchange_preflight and 3 more
Contribution Exchange costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http contribution-exchange-mcp https://signalaf.com/api/exchange/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
6 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Determine whether a domain publishes a Contribution Exchange profile. Returns the canonical Exchange manifest, policy URLs, signal URLs, and whether the domain is self-hosted or delegated to a Steward. Read-only — does not propose, commit, or authorize anything. Enforces HTTPS, redirect limits, timeouts, and SSRF protections (blocks loopback, link-local, private-network, and metadata-service targe
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | Domain name or HTTPS URL to check (e.g. 'signalaf.com' or 'https://signalaf.com'). Normalized to hostname. |
Fetch the canonical Contribution Exchange policy for a domain or its delegated Steward. Returns authority ceilings, consideration limits, human-review requirements, and supported behavior. Read-only — does not mutate state or perform preflight evaluation. Distinguishes a missing policy from an unavailable service.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | Domain name to fetch policy for. |
Evaluate a proposed contribution against the same policy logic used by the real proposal flow. Returns whether the proposal is likely to be auto-engaged, accepted for review, escalated to a human, or rejected as invalid. READ-ONLY: performs no proposal insertion, notification, event creation, or state transition. The result is advisory and time-bound — a favorable preflight does NOT guarantee enga
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | Target domain for the proposed contribution. |
| category | string | yes | Contribution category (e.g. 'technical', 'accessibility', 'documentation', 'research'). |
| consideration | array | no | Requested consideration (cash, royalty, reciprocal_access, attribution, referral, other). Advertised consideration is NOT binding until accepted through Commitment. |
| required_authorization | object | no | Authority requested (inspect_public, sandbox_test, repository_write, private_data, credential_access, production_modify, deploy, penetration_testing). |
| confidence | object | no | Confidence in the observation (score 0-1 and basis). |
List domain-published Exchange Signals (problems, requests, challenges, bounties, verification tasks, discoveries, experiments). Read-only. Returns canonical URLs, signal revision, revision hash, and status. Signal status is DISTINCT from exchange status — a signal does not create a Commitment or authorize execution. Supports the same filters and pagination as the HTTP API.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | no | Filter by publisher domain. |
| type | string | no | Filter by signal type. |
| status | string | no | Filter by signal status. |
| label | string | no | Filter by label. |
| verification_mode | string | no | Filter by verification mode. |
| consideration_mode | string | no | Filter by consideration mode. |
| accepting_attempts | boolean | no | Only return signals currently accepting attempts. |
| published_after | string | no | ISO 8601 timestamp — only signals published after this. |
| expires_before | string | no | ISO 8601 timestamp — only signals expiring before this. |
| cursor | string | no | Pagination cursor from a previous response. |
| limit | integer | no | Maximum signals to return (1-100, default 50). |
Get full detail for a single Exchange Signal by ID. Read-only. Returns the complete signal including constraints, participation rules, verification configuration, consideration declaration, and follow-on behavior. A signal does NOT create a Commitment, authorize execution, or guarantee payment.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| signal_id | string | yes | Signal ID. |
Get detail for a signal attempt. Read-only. Enforces attempt visibility — actors may only read their own private attempts. Returns attempt status and verification result if available. Attempt status is NOT an exchange state. Verification is Steward-controlled and cannot be self-asserted.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| signal_id | string | yes | Signal ID. |
| attempt_id | string | yes | Attempt ID. |

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Contribution Exchange can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
