Registry nameai.kaiv/bridge

Install

Overview

Description from the maker (original English)

Turn any OpenAPI/Swagger spec or REST API docs link into a managed MCP server. Free account.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

  "mcpServers": {
    "bridge": {
      "url": "https://api.kaiv.ai/api/bridge/manage/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "bridge": {
      "type": "http",
      "url": "https://api.kaiv.ai/api/bridge/manage/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Kaiva Bridge safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.4) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Fomu MCP

Kaiva Bridge

Kaiva Bridge turns your API, database or documents into a managed MCP server that Claude, ChatGPT, Cursor, VS Code and other AI clients can use. This page covers the Kaiva Bridge connector, ai.kaiv/bridge, first; the command-line tool follows.

Kaiva Bridge as an MCP connector (ai.kaiv/bridge)

Kaiva Bridge is also an MCP server itself, so your AI client can create and manage MCP servers from inside a chat. It is listed in the official MCP Registry as ai.kaiv/bridge and in Claude's connector directory.

  • Address: https://api.kaiv.ai/api/bridge/manage/mcp (Streamable HTTP)
  • Sign-in: OAuth 2.1 with your Kaiva Bridge account (free, no card). No key to copy.
  • Tools: list_my_servers, get_server, create_server (drafts a server from an OpenAPI spec URL) and reintrospect_server (refreshes a server's tools when the API changes).

The connector drafts and lists. Publishing a server and switching its tools on happen in the console, by you.

VS Code and GitHub Copilot: click Add to VS Code on kaiv.ai/bridge, or run *MCP: Add Server* in VS Code with the address above, then sign in when asked. Claude: claude.ai/directory/kaiva-bridge. Claude Code: claude mcp add --transport http --scope user kaiva-bridge https://api.kaiv.ai/api/bridge/manage/mcp. Cursor and ChatGPT: the Add menu on kaiv.ai/bridge.

Then ask: "List my Kaiva Bridge servers" or "Create a Kaiva Bridge server from https://petstore3.swagger.io/api/v3/openapi.json".

The command-line tool

Publish any API or database as a live MCP server, from your terminal.

Kaiva Bridge turns an OpenAPI spec, a database (PostgreSQL, MySQL, MariaDB or SQL Server) or a remote MCP server into a managed MCP server your agents can call. This CLI drives it over the Management API. Every setup command is safe to run again.

For your coding agent

Connect your AI agent to APIs, databases and documents with Kaiva Bridge. Install the skill so your coding agent can set up managed MCP connections for you. Try public APIs without an account.

Works with Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and other compatible coding agents.

npx skills add ai-kaiva/bridge

Install

Nothing to install. Node 18+ has everything:

npx @kaiva/bridge help

Try it with no account

For a public API spec, one command gives you a working MCP server. No account, no login:

npx @kaiva/bridge try --openapi https://petstore3.swagger.io/api/v3/openapi.json

You get the server's address, a key for that one server, and a claim link. The server offers only the spec's GET operations, and lasts 72 hours or 500 calls. Open the claim link to keep it in your workspace: it keeps its address and your plan's limits apply. The key stops working at claim, so connect your AI client again from the console. Then you can add an API key and switch on other operations. Coding agents can do this themselves (--json prints one JSON object).

In a cloud agent sandbox (Codex cloud, Claude Code on the web), allow the domains api.kaiv.ai and registry.npmjs.org first: their network access is off or limited by default.

Claude Code plugin

claude plugin marketplace add ai-kaiva/bridge

claude plugin install kaiva-bridge@kaiva

Or copy just the skill: npx @kaiva/bridge skill install.

Postgres on your machine, no account

For a Postgres database that only the AI clients on your machine use, Kaiva Postgres MCP is a free, open-source MCP server that runs locally and only reads. It replaces the archived @modelcontextprotocol/server-postgres: change the package name and nothing else changes.

claude mcp add postgres -- npx -y @kaiva/postgres-mcp postgresql://localhost/mydb

or, from the same plugin marketplace as above (reads DATABASE_URL from your environment)

claude plugin install postgres-mcp@kaiva

When you need the same database in Claude.ai or ChatGPT, or for your team, push --db below serves it from Bridge.

Auth

npx @kaiva/bridge login

The terminal shows a code and opens the console. Enter the code there and approve it (owner or admin of the workspace). The key is saved for this machine in ~/.config/kaiva-bridge/credentials.json, readable only by you. whoami shows the workspace and key in use; logout revokes the key and removes it.

For CI and scripts, use a Management key from the console (Keys & access, key type Management) instead. When set, it is used in place of a saved login:

export KAIVA_BRIDGE_TOKEN=kv_mgmt_...

logout revokes only a saved login. A key you supply in KAIVA_BRIDGE_TOKEN is yours to manage: unset it, and revoke it in the console when it is no longer needed. Signing in again revokes the login it replaces.

Management keys are refused by the MCP gateway, and gateway keys are refused by the Management API: the two credential types are never interchangeable.

Quickstart: source to live server

# An API spec (only operations that read are exposed with --read-only)

npx @kaiva/bridge push my-api --openapi https://api.example.com/openapi.json --read-only

A database: DATABASE_URL from the environment or .env; Postgres, MySQL, MariaDB or SQL Server

npx @kaiva/bridge push shop-db --db --read-only

→ LIVE https://api.kaiv.ai/api/bridge/mcp/shop-db-a1b2c3d4

→ check first call: get_orders answered in 84ms (and what the AI is given)

Documents: PDF, Word, PNG, JPEG, text or Markdown files, or a folder of them

npx @kaiva/bridge push handbook --docs ./policies

waits until each file is read, then → LIVE https://api.kaiv.ai/api/bridge/mcp/handbook-a1b2c3d4

npx @kaiva/bridge install my-api --client claude-code # or --client cursor

install adds the server to Claude Code (this folder's .mcp.json, or --global) or Cursor (~/.cursor/mcp.json, or --project), keeping every other entry. The client signs in with your Kaiva account the first time; --key writes a key for this one server instead. --dry-run shows the change; uninstall removes it. For any other MCP client, key --label --replace makes a gateway key to paste with the endpoint. Run the same commands again and nothing is duplicated: push reuses the server with that name, install leaves an existing entry as it is, and key --replace swaps the key with that label.

Let your coding agent do it

npx @kaiva/bridge skill install        # adds the setup skill to Claude Code (~/.claude/skills)

Then ask: "connect my database to Claude Code with Kaiva Bridge". The skill runs the commands below, asks you before connecting without certificate checks or exposing operations that write, and confirms with a first tool call.

Examples

Runnable scripts in examples/:

  • database-to-claude-code.sh: a Postgres, MySQL or MariaDB database into Claude Code
  • openapi-to-cursor.sh: an OpenAPI spec into Cursor for this project
  • call-from-your-app.mjs: call your MCP server from your own Node app, no dependencies

Commands

CommandWhat it does
push --openapi Create + introspect + expose + publish from an OpenAPI spec
push --mcp Wrap an existing remote MCP server, choosing which of its tools to offer
push --postgres Read-only tools from a Postgres database
push --mysql Read-only tools from a MySQL or MariaDB database
push --graphql Read tools from a GraphQL API's queries (mutations are not offered)
push --sqlserver Read-only tools from a SQL Server or Azure SQL database (sqlserver://… or Server=…;Database=…;User ID=…;Password=…)
push --docs Documents your AI can search and read, page by page; the same file name again replaces that document. --no-wait returns once the files are sent
push --db [--db-env NAME]The database in DATABASE_URL (or NAME), from the environment or .env.local/.env; the engine is told apart by the address, which never appears on the command line
push … --read-onlyExpose only operations that read; writes stay off until you choose them
push … --no-checkSkip the setup check every push and try ends with: one real call, writes switched on, the tool list's size and tables that look private
push … --ca-file / --no-verify-tlsA database with a self-signed certificate: check it against your provider's CA, or connect without checking
login [--no-browser]Approve this machine in the console and save a key for it
whoamiThe workspace, account and key in use
logoutRevoke this machine's key and remove it
skill install [--project]Add the setup skill for coding agents
`install --client claude-code\cursor`Add a live server to the client's config; --key, --dry-run, --global (Claude Code), --project (Cursor)
`uninstall --client claude-code\cursor`Remove it, and revoke a key install added
doctor [--call ]Check reachability, sign-in, publication, the MCP handshake and tool list; each step passes, fails with a code and a fix, or says it did not run. --call makes one call with a tool that reads. Ends with a receipt for support (no secrets)
serversList servers with state and source
publish Publish a draft server
key [--label L] [--replace]Mint a server-scoped gateway key (shown once); --replace revokes the earlier key with that label
introspect Re-read the source. Exits 3 if a contract change was held
revisions Contract history: when it changed and which tool
promote Publish the held change
reject Discard it and restore what is being served
auto-publish [--off]Publish contract changes without review
invoke [--args '{"k":"v"}']Test-call a tool through the real governed path (audited)
logs [--limit 50]Tail the audit log
metrics [--range 24h]Workspace KPIs (1h · 24h · 7d · 30d)

--json on push, key, install, whoami and doctor prints one JSON result on stdout (progress goes to stderr), for scripts and agents. KAIVA_BRIDGE_URL overrides the API base (defaults to https://api.kaiv.ai/api/bridge/v1).
