Matih Mcp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Matih Mcp (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Connect AI clients (Claude Desktop, ChatGPT, Cursor, …) to the Matih data platform over the Model Context Protocol. Write SQL, profile tables, run analyses + charts, manage dashboards, and upload files — all through MCP tools, with OAuth/PKCE auth and PII-safe egress.
New here? See [QUICKSTART.md](./QUICKSTART.md) for a step-by-step customer guide — create a token, connect Claude Desktop / Cursor, and copy-paste curl smoke tests — plus a troubleshooting table.Add to your client's MCP config. The token is delivered via the environment — never as a CLI flag (which leaks into the OS process list):
{
"mcpServers": {
"matih": {
"command": "npx",
"args": ["-y", "@matihlabs/mcp", "https://<slug>.app.matih.ai/api/v1/mcp"],
"env": { "MATIH_MCP_TOKEN": "<your Matih bearer token>" }
}
}
}The bridge turns the remote Matih HTTP MCP endpoint into a local stdio MCP server, forwarding every tools/call, resources/read, and prompts/get to Matih.
Endpoint: replace<slug>with your workspace slug — your Matih app lives athttps://<slug>.app.matih.ai(the bareapp.matih.aihost does not resolve). Get amat_agt_…token from Settings → Developer Tokens. See QUICKSTART.md for the full walkthrough.
import { McpClient, MatihTools, StaticTokenProvider } from "@matihlabs/mcp";
const client = new McpClient({
endpoint: "https://<slug>.app.matih.ai/api/v1/mcp",
tokenProvider: new StaticTokenProvider(process.env.MATIH_MCP_TOKEN!),
});
// discovery-first: fetch the LIVE tool surface (auto-initializes + caches)
const live = await client.tools();
console.log(live.map((t) => t.name));
// call ANY tool generically — including Beta tools with no typed wrapper
const hot = await client.callTool("get_hot_context", {});
// typed convenience wrappers for the 34 STABLE tools
const graph = await new MatihTools(client).exploreGraph({ query: "orders", depth: 2 });
const matih = new MatihTools(client);
const result = await matih.runSql({ connection_id: "<id>", sql: "select 1" });import { McpClient, OAuthTokenProvider } from "@matihlabs/mcp";
const tokenProvider = new OAuthTokenProvider({
resourceMetadataUrl: "https://<slug>.app.matih.ai/.well-known/oauth-protected-resource/api/v1/mcp",
clientId: "<registered client id>",
acquire: async ({ metadata, clientId, resource }) => {
// open metadata.authorization_endpoint (PKCE S256, resource=<resource>),
// capture the code at your redirect_uri, return { code, verifier, redirectUri }.
},
});The provider runs RFC 9728 → RFC 8414 discovery, PKCE S256, RFC 8707 resource-bound tokens, caches, and refreshes; a 401 invalid_token triggers one re-auth.
Discovery is the primary API — await client.tools() returns the live tool descriptors and client.callTool(name, args) reaches every advertised tool. The typed facade (MatihTools) covers the 34 stable tools (STABLE_TOOL_NAMES):
ask (natural-language → grounded answer + the SQL it ran),run_sql, run_analysis, get_query_result, export_result
list_connections, list_databases, list_schemas,list_tables, describe_table, profile_table
search_ontology, get_entity,get_relationships, get_semantic_model, get_glossary, explore_graph
get_metric, run_metric, draft_metric(write-class — proposes a DRAFT metric_def into the human-gated DRAFT → REVIEW → APPROVED → SHIP pipeline), list_metric_drafts, export_semantic_model (OSI), get_taxonomy, export_taxonomy (SKOS)
create_chart, create_dashboard, get_dashboard,publish_dashboard
upload_file, upload_status, create_upload_url, finalize_uploadwhoami, get_scopeThe 1 Beta tool (BETA_TOOL_NAMES: get_hot_context) is deliberately not hard-typed while its shape may evolve — call it via client.callTool(name, args). The governed metrics & taxonomy group and explore_graph were promoted from Beta to stable in July 2026 (PDR W3-1).
Plus catalog / lineage resources and the explain_metric prompt. Every tool is bounded by the developer token's scope (connections + capabilities you grant in Settings) and never exceeds your own permissions — get_scope shows exactly what a token allows.
