How do I install Kyma API?

Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Kyma API need an API key?

The publisher lists these environment variables: KYMA_MCP_KEY.

When was Kyma API last checked?

Last checked 2026-11-08. Live model catalog with prices and measured uptime, rankings, credits and spend, spend-capped chat.

Questions

Hosted, remote, OAuth sign-in. Streamable HTTP with OAuth 2.1, PKCE and dynamic client registration. No API key is pasted into the client.
A dedicated key per connection. Separate from your REST API keys, capped at $10 per 30 days by default (adjustable from $1 to $500 on the approval screen or at kymaapi.com/integrations), revocable at any time.
Read tools never charge. Catalog, pricing, rankings, uptime, credits, spend, your usage and your requests are free to call and auto-approved by most clients.
send_message is priced before it spends. The client must allow it first; max_cost_usd is enforced by deriving a max_tokens that fits the ceiling from the catalog price, so a call above it is refused before anything is sent. Every reply reports what the call cost, what has been spent and the cap.
Measured uptime, not a promise. get_model_uptime returns the 30-day rate per model from kymaapi.com/status. If a route fails mid-request, Kyma retries the same model on another route.
A read-only endpoint for reviewers. https://mcp.kymaapi.com/mcp/readonly accepts the same tokens but keeps only read scopes for the request: no send_message, no set_low_balance_alert, whatever the grant was approved with. Metadata: /.well-known/oauth-protected-resource/mcp/readonly.
Beyond chat. The same Kyma key covers speech-to-text, text-to-speech, embeddings, rerank, image and video through the REST API; list_models shows all of them.

Install

claude mcp add --transport http kyma https://mcp.kymaapi.com/mcp

Run /mcp to sign in. This repository is also a Claude Code plugin (.claude-plugin/plugin.json + .mcp.json).

Settings → Connectors → Add custom connector → paste https://mcp.kymaapi.com/mcp → sign in with Kyma.

One click: Add to Cursor

Or in .cursor/mcp.json:

{ "mcpServers": { "kyma": { "url": "https://mcp.kymaapi.com/mcp" } } }

One click: Install in VS Code

Or in .vscode/mcp.json:

{ "servers": { "kyma": { "type": "http", "url": "https://mcp.kymaapi.com/mcp" } } }

# ~/.codex/config.toml
[mcp_servers.kyma]
url = "https://mcp.kymaapi.com/mcp"

codex mcp login kyma

Cline → MCP Servers → Configure MCP Servers:

{ "mcpServers": { "kyma": { "url": "https://mcp.kymaapi.com/mcp", "type": "streamableHttp" } } }

Cline CLI: cline mcp add kyma https://mcp.kymaapi.com/mcp --transport streamableHttp --yes. Cline asks you to sign in with Kyma on first use.

gemini extensions install https://github.com/kyma-api/kyma-mcp-plugin

The first tool call opens a browser for OAuth sign-in, handled by Gemini CLI.

grok.com: Connectors → New Connector → Custom → paste the URL.
Grok Build: this repository is a Claude Code format plugin; Grok Build loads it as-is.

Settings → Connectors (Plus, Pro, Business, Enterprise, Edu) → add the URL → sign in. ChatGPT connections never see get_topup_link.

{ "mcpServers": { "kyma": { "command": "npx", "args": ["-y", "@kyma-api/mcp-server"] } } }

The bridge runs mcp-remote against the hosted URL, so the tools are exactly the hosted ones. Set KYMA_MCP_KEY=km-… (a Kyma MCP key from kymaapi.com/integrations, not a REST kyma-… key) to skip the browser. Source: bridge/.

Tools

18 tools. 16 appear on a default connection; list_keys and set_low_balance_alert appear when their optional scopes are granted on the approval screen.

Tool	What it does	Scope	Approval
`list_models`	Live model catalog with prices, context window and capabilities	`models.read`	auto, read-only
`get_model`	One model's details	`models.read`	auto, read-only
`list_pricing`	Prices across the catalog	`models.read`	auto, read-only
`list_rankings`	Top models and apps from real traffic	`models.read`	auto, read-only
`get_model_uptime`	Measured 30-day uptime per model	`models.read`	auto, read-only
`recommend_model`	Best model and config for Cline, Cursor, Claude Code and other agents	`models.read`	auto, read-only
`search_docs`	Search Kyma docs	`models.read`	auto, read-only
`ping`	Health check	`models.read`	auto, read-only
`get_credits`	Your balance	`usage.read`	auto, read-only
`get_spend`	This connection's cap, spent, remaining and reset date	`usage.read`	auto, read-only
`get_usage`	Your requests, tokens and cost by model over a window	`usage.read`	auto, read-only
`get_request`	One request by id: model served, tokens, cost, routes tried	`usage.read`	auto, read-only
`estimate_cost`	What a call would cost before you make it	`models.read`	auto, read-only
`get_transactions`

Every send_message reply carries cost, spent_usd and spend_cap_usd, plus structuredContent with the model that served it and the routes tried. get_spend shows what is left before you call it.

Security and spend

What a connection can do: read the catalog, prices, rankings, uptime, your balance and this connection's spend; send chat completions up to its cap; with optional scopes, list your keys masked and set a low-balance alert.
What it can never do: create or delete API keys, change billing or payment methods, buy credits, register accounts, or see provider internals. Those scopes do not exist on this server.
Spend cap: each connection gets a dedicated key with its own cap, $10 per 30 days by default, adjustable from $1 to $500. The cap is enforced on the server; when it is reached send_message returns an error until the window resets or you raise the cap at kymaapi.com/integrations.
Tokens and keys: access tokens live 7 days, refresh tokens 90 days and rotate on use; connection keys are stored hashed (SHA-256) and can be revoked without touching your REST API keys.
Prompt injection: model output that reaches your agent is untrusted text. Keep your client's confirmation prompt on for send_message, and do not let the agent paste keys or balances into other tools.
Data: request logs are kept 90 days for billing reconciliation and abuse handling, then deleted. Kyma does not train on customer data. Privacy: kymaapi.com/privacy.

Skills

Three skills teach an agent how to use the tools well: pick-a-model (compare price, measured uptime and fit), check-spend-and-credits (balance, cap, remaining, reset date), send-a-test-completion (one billed call, only after an explicit Allow). They live in skills/ and install into any agent that reads skills:

npx skills add kyma-api/kyma-mcp-plugin

Examples

Prompts you can paste once connected:

"Which models under $1 per million output tokens have the best 30-day uptime?"
"Recommend a model and config for Cline, then show its price."
"How much of this connection's budget is left, and when does it reset?"
"Send 'summarize this in one line' to qwen-3.6-plus and tell me what it cost."
"Show the top apps on Kyma rankings this week."

Troubleshooting

Sign-in loops or "connector failed": remove the connection and add it again; the client's stored token may belong to a revoked connection. Check kymaapi.com/integrations for the active list.
send_message says the cap is reached: raise the cap at kymaapi.com/integrations or wait for the 30-day window to reset; get_spend shows the date.
A tool returns 403 insufficient scope: the connection was approved without that optional scope. Reconnect and tick it on the approval screen.
Stdio bridge cannot sign in: set KYMA_MCP_KEY to a Kyma MCP key (km-…) created at kymaapi.com/integrations; REST kyma-… keys are rejected on purpose.
Remote connections drop: some clients need a reconnect after long idle periods; the server itself is stateless.
