+# Cedar Schema Integration for MCP Tool Governance
+
+TypeScript integration that auto-generates Cedar authorization schemas from MCP tool descriptions and uses them for runtime policy enforcement.
+
+Built on [protect-mcp](https://www.npmjs.com/package/protect-mcp), the security gateway for MCP servers and Claude Code. This example shows how to generate Cedar schemas from MCP `tools/list`, enabling typed policies that reference tool input attributes.
+
+## What this does
+
+1. **Reads MCP tool descriptions** (JSON Schema for each tool's inputs)
+2. **Generates a Cedar schema** with per-tool actions and typed input context
+3. **Passes the schema to `@cedar-policy/cedar-wasm`** for validated policy evaluation
+4. **Every allow/deny decision produces an Ed25519-signed receipt** (IETF Internet-Draft: `draft-farley-acta-signed-receipts`)
+
+## Schema generation
+
+The schema generator maps MCP tool descriptions to Cedar entity/action types:
+
+| MCP Tool | Cedar Action | Cedar Context |
+|---|---|---|
+| `read_file(path: string)` | `Action::"read_file"` | `context.input.path: String` |
+| `execute_command(command: string, args: string[])` | `Action::"execute_command"` | `context.input.command: String, context.input.args: Set<String>` |
+
+All per-tool actions are children of a blanket `Action::"MCP::Tool::call"` action, so policies can match individual tools or all tools:
+
+```cedar
+// Match all tool calls
+forbid(principal, action == Action::"MCP::Tool::call", resource);
+
+// Match specific tool with typed input
+permit(principal, action == Action::"read_file", resource)
+when { context.input.path like "./workspace/*" };
+```
+
+### JSON Schema to Cedar type mapping
+
+| JSON Schema | Cedar Type |
+|---|---|
+| `string` | `String` |
+| `integer` / `number` | `Long` |
+| `boolean` | `Bool` |
+| `array` | `Set<T>` |
+| `object` (with properties) | Record type |
+
+Required properties are mapped without `?`. Optional properties are mapped with `?`.
+
+## Quick start
+
+### With Claude Code (recommended)
+
+```bash
+npx protect-mcp init-hooks   # generates Cedar policies + hook config + signing keys
+npx protect-mcp serve        # starts hook server with schema-validated Cedar evaluation
+```
+
+### Programmatic usage
+
+```typescript
+import { generateCedarSchema, evaluateCedar, loadCedarPolicies } from 'protect-mcp';
+
+// MCP tools (from tools/list response)
+const tools = [
+  {
+    name: 'read_file',
+    description: 'Read a file',
+    inputSchema: {
+      type: 'object',
+      properties: { path: { type: 'string' } },
+      required: ['path'],
+    },
+  },
+  {
+    name: 'execute_command',
+    description: 'Run a shell command',
+    inputSchema: {
+      type: 'object',
+      properties: {
+        command: { type: 'string' },
+        args: { type: 'array', items: { type: 'string' } },
+      },
+      required: ['command'],
+    },
+  },
+];
+
+// Generate Cedar schema from tool descriptions
+const schema = generateCedarSchema(tools);
+console.log(schema.schemaText);  // Human-readable .cedarschema
+console.log(schema.schemaJson);  // JSON for Cedar WASM
+
+// Load Cedar policies from disk
+const policies = loadCedarPolicies('./policies');
+
+// Evaluate with schema validation
+const result = await evaluateCedar(policies, {
+  tool: 'read_file',
+  tier: 'unknown',
+  toolInput: { path: './workspace/README.md' },
+}, { schemaJson: schema.schemaJson });
+
+console.log(result);
+// { allowed: true, metadata: { policy_digest: 'a3f8...' } }
+```
+
+## Generated schema example
+
+For the tools above, `generateCedarSchema()` produces:
+
+```cedarschema
+namespace ScopeBlind {
+
+  entity Agent = {
+    "tier": String,
+    "agent_id": String?
+  };
+
+  entity Tool;
+
+  type read_file_Input = {
+    "path": String
+  };
+
+  type execute_command_Input = {
+    "command": String,
+    "args": Set<String>?
+  };
+
+  action "read_file" in [Action::"MCP::Tool::call"] appliesTo {
+    principal: [Agent],
+    resource: [Tool],
+    context: {
+      "input": read_file_Input,
+      "tier": String
+    }
+  };
+
+  action "execute_command" in [Action::"MCP::Tool::call"] appliesTo {
+    principal: [Agent],
+    resource: [Tool],
+    context: {
+      "input": execute_command_Input,
+      "tier": String
+    }
+  };
+
+  action "MCP::Tool::call" appliesTo {
+    principal: [Agent],
+    resource: [Tool],
+    context: {
+      "tier": String
+    }
+  };
+
+}
+```
+
+## Compatibility with cedar-policy-mcp-schema-generator (Rust)
+
+This TypeScript implementation is compatible with the [Rust schema generator](../rust/cedar-policy-mcp-schema-generator/):
+
+- Same entity model: `Agent` (principal), `Tool` (resource)
+- Same action hierarchy: per-tool actions as children of `MCP::Tool::call`
+- Same type mapping: JSON Schema → Cedar types
+- Schema stubs generated by `generateSchemaStub()` use `@mcp_principal` / `@mcp_resource` annotations
+
+The TypeScript version is designed for Node.js environments where the Rust binary is not available (e.g., `npx protect-mcp` installs). For environments with Rust tooling, the Rust generator provides additional features (union types, tagged entities, output schemas).
+
+## Example Cedar policies
+
+```cedar
+// Block shell execution (prevents prompt injection attacks)
+@id("block-shell")
+forbid(
+  principal,
+  action == Action::"MCP::Tool::call",
+  resource == Tool::"execute_command"
+);
+
+// Allow reads only within workspace
+@id("workspace-reads")
+permit(
+  principal,
+  action == Action::"read_file",
+  resource
+)
+when { context.input.path like "./workspace/*" };
+
+// Rate-limit write operations for untrusted agents
+@id("untrusted-write-limit")
+forbid(
+  principal,
+  action == Action::"write_file",
+  resource
+)
+when { context.tier == "unknown" };
+```
