Generated by Astrail SDK Factory for ${server.name}.
\`astrail.yaml\` is the reviewable source for generated SDK names, auth options, endpoint grouping, publish switches, and regeneration automation.
## Inferred Contract
| Area | Value |
| --- | --- |
| Endpoints | ${endpoints.length} |
| Auth-required endpoints | ${summary.authRequired} |
| Auth schemes | ${summary.authSchemes.length > 0 ? summary.authSchemes.map((scheme) => `\`${scheme}\``).join(", ") : "none detected"} |

| Pagination | ${summary.pagination.map(([name, count]) => `${name}: ${count}`).join(", ") || "none detected"} |
## Override Points
- Package names and publish switches live under \`targets\`.
- Runtime API key injection lives under \`client_settings.opts.api_key\`.
- Resource grouping and method names live under \`resources\`.
- Release PR automation lives under \`customization.automation\`.
- Durable hand-written wrappers live in \`custom/custom-methods.yaml\`.
## Review Rule
If the upstream OpenAPI spec changes, review \`astrail.yaml\`, \`openapi/inference-report.json\`, \`docs/REFERENCE.md\`, and \`policies/agent-policy.json\` together before publishing new packages.

## Runtime Contract
Every target calls the hosted MCP endpoint over HTTP JSON-RPC:
- \`initialize\`
- \`tools/list\`
- \`tools/call\`
- \`search_docs\` and \`execute\` when Code Mode is enabled
- \`invoke_api_endpoint\` when dynamic endpoint catalogs are enabled
Endpoint-specific SDK methods compile down to \`callEndpoint(endpointKey, arguments)\`. The hosted Astrail endpoint stays the source of truth, so auth boundaries, logs, trace IDs, and endpoint-map safety stay centralized.
## Example Shape
\`\`\`ts
${example}
\`\`\`
## Customization
Edit \`astrail.yaml\` for package names, publish switches, naming conventions, auth environment variables, and CI automation. Add hand-written methods in \`custom/custom-methods.yaml\` so custom wrappers survive regeneration.

## Code Mode
If this server exposes \`search_docs\` and \`execute\`, agents should search first, then submit SDK-shaped calls:
\`search_docs\` ranks endpoint docs from SDK method names, operation IDs, summaries, paths, tags, argument fields, auth schemes, pagination fields, and response hints. Use \`detail: "compact"\` for discovery, \`"schema"\` for exact argument schemas, \`"examples"\` for call shapes, and \`"auth"\` for credential requirements.

\`\`\`
Astrail statically maps supported client calls to endpoint-map execution. It does not eval arbitrary JavaScript inside the hosted runtime.
${server.runtime_policy?.x402?.enabled ? `
## Caller-signed x402 retry
When a tool returns \`x402_payment_required\`, have the end user sign one offered option outside Astrail, then retry the same request with the x402 v2 header:
\`\`\`bash
curl -sS -X POST "${endpoint}" \\
-H 'Content-Type: application/json' \\
-H "Authorization: Bearer $ASTRAIL_API_KEY" \\
-H "PAYMENT-SIGNATURE: $X402_PAYMENT_SIGNATURE" \\
--data '{"jsonrpc":"2.0","id":5,"method":"tools/call","params":{"name":"paid_tool","arguments":{}}}'

The API key must be bound to the paying end-user ID. Astrail enforces the configured network, asset, spend, approval, domain, and replay policy without storing wallet keys or funds.

## Remote HTTP
Use this for clients that support hosted MCP over HTTP:
Replace \`${ASTRAIL_API_KEY_PLACEHOLDER}\` with a secret-managed token for private endpoints. Do not commit a live token or leave the placeholder as a literal bearer token.
\`\`\`json
{
"name": "${slug(server.name)}",
"url": "${endpoint}",
"headers": {
"Authorization": "${ASTRAIL_AUTH_HEADER_PLACEHOLDER}"
}
}
\`\`\`
## CLI Bridge
The generated MCP npm bridge package is \`${mcpPackage}\`. It exposes a stdio MCP server command for clients that do not support remote HTTP MCP yet.
\`\`\`bash
ASTRAIL_MCP_ENDPOINT="${endpoint}" \\
ASTRAIL_API_KEY="$ASTRAIL_API_KEY" \\
npx ${mcpPackage}
\`\`\`
The generated utility CLI package is \`${packageName}-cli\`. It can initialize the endpoint, list tools, search docs, execute Code Mode snippets, and call tools from scripts.
## Cursor
Remote HTTP, when available:
\`\`\`json
{
"mcpServers": {
"${slug(server.name)}": {
"url": "${endpoint}",
"headers": {
"Authorization": "${ASTRAIL_AUTH_HEADER_PLACEHOLDER}"
}
}
}
}
\`\`\`
Stdio bridge fallback:
\`\`\`json
{
"mcpServers": {
"${slug(server.name)}": {
"command": "npx",
"args": ["-y", "${mcpPackage}"],
"env": {
"ASTRAIL_MCP_ENDPOINT": "${endpoint}",
"ASTRAIL_API_KEY": "${ASTRAIL_API_KEY_PLACEHOLDER}"
}
}
}
}
\`\`\`
## Claude Desktop
Add this to \`claude_desktop_config.json\`:
\`\`\`json
{
"mcpServers": {
"${slug(server.name)}": {
"command": "npx",
"args": ["-y", "${mcpPackage}"],
"env": {
"ASTRAIL_MCP_ENDPOINT": "${endpoint}",
"ASTRAIL_API_KEY": "${ASTRAIL_API_KEY_PLACEHOLDER}"
}
}
}
}
\`\`\`
## Claude Code
Use a JSON import or command equivalent to:
\`\`\`bash
claude mcp add-json ${slug(server.name)} '{
"command": "npx",
"args": ["-y", "${mcpPackage}"],
"env": {
"ASTRAIL_MCP_ENDPOINT": "${endpoint}",
"ASTRAIL_API_KEY": "${ASTRAIL_API_KEY_PLACEHOLDER}"
}
}'
\`\`\`
## VS Code-style mcpServers.json
\`\`\`json
{
"servers": {
"${slug(server.name)}": {
"type": "stdio",
"command": "npx",
"args": ["-y", "${mcpPackage}"],
"env": {
"ASTRAIL_MCP_ENDPOINT": "${endpoint}",
"ASTRAIL_API_KEY": "${ASTRAIL_API_KEY_PLACEHOLDER}"
}
}
}
}
\`\`\`
## Manifests
- \`mcp/manifest.json\` describes runtime capabilities and tool metadata.
- \`mcp/install.json\` contains client-oriented connection data.
- \`mcp/mcpb-manifest.json\` is a package manifest template for clients that support MCP bundle-style installers.
- \`docs/MCPB_AND_DEEPLINKS.md\` contains placeholder MCPB and deep-link copy for product surfaces.

Generated by Astrail SDK Factory for ${server.name}.

## Extra Astrail Surface
- Hosted endpoint is live immediately; SDKs call the hosted MCP runtime instead of forcing every customer to stand up generated infrastructure first.
- Code Mode is deterministic no-eval endpoint-map execution.
- Website-to-MCP covers cases where a perfect OpenAPI spec does not exist yet.
- Generated policy and eval artifacts make agent safety and performance reviewable during PR review.
## Endpoint Coverage
- Endpoints exported: ${endpoints.length}
- Auth-required endpoints: ${endpoints.filter((endpoint) => endpoint.requiresAuth).length}
- Read endpoints: ${endpoints.filter((endpoint) => endpoint.operation === "read").length}
- Write endpoints: ${endpoints.filter((endpoint) => endpoint.operation === "write").length}
- Destructive endpoints: ${endpoints.filter((endpoint) => endpoint.operation === "destructive").length}
## Review Checklist
- Run \`node scripts/verify-generated-sdk.mjs\`.
- Run \`ASTRAIL_MCP_ENDPOINT=... node scripts/run-astrail-evals.mjs\`.
- Inspect \`openapi/diagnostics.json\`.
- Inspect \`policies/agent-policy.json\` before allowing write/destructive tools.
- Update package names and publish flags in \`astrail.yaml\`.

## Release Gates
1. Run \`node scripts/verify-generated-sdk.mjs\`.
2. Run \`node scripts/check-release-readiness.mjs\`.
3. Run target builds locally or in CI.
4. Enable only the workflow inputs you intend to publish.
5. Type \`publish\` into \`confirm_publish\` for the final release run.
6. Publish from protected branches or signed tags.
## Secret Contract
The generated workflow also requires \`confirm_publish=publish\` before any package publish job can run. It fails before publishing if a required credential is missing. That gives reviewers a clean signal: verification can pass without secrets, but a release cannot silently become a fake success.

Publishing is opt-in. Astrail generates package scaffolds; your repo owns package names, credentials, approvals, and release timing.
## Suggested Release Gates
1. Pull the latest bundle with \`scripts/pull-astrail-sdk.mjs\`.
2. Review \`astrail.yaml\`, \`docs/REFERENCE.md\`, \`docs/RELEASE_MATRIX.md\`, and \`mcp/manifest.json\`.
3. Run \`node scripts/verify-generated-sdk.mjs\`.
4. Run \`node scripts/check-release-readiness.mjs\`.
5. Run any installed language-specific checks for TypeScript, Python, Go, Java, Kotlin, Ruby, C#, and PHP.
6. Merge the generated PR.
7. Publish only from protected branches/tags.
## Package Managers
| Target | Package manager | Credential secret |
| --- | --- | --- |
| TypeScript | npm | \`NPM_TOKEN\` |
| MCP bridge | npm | \`NPM_TOKEN\` |
| Python | PyPI | \`PYPI_API_TOKEN\` |
| Java/Kotlin | Maven Central | \`MAVEN_USERNAME\`, \`MAVEN_PASSWORD\`, signing secrets |
| Ruby | RubyGems | \`RUBYGEMS_API_KEY\` |
| C# | NuGet | \`NUGET_API_KEY\` |
| PHP | Packagist/Git tag | \`PACKAGIST_TOKEN\` |
| Go | Git tag/module proxy | GitHub release token |
| Terraform | Terraform Registry | registry token |
| Docker runtime proxy | GHCR/OCI registry | registry token |
## GitHub Action
\`.github/workflows/astrail-publish.yml\` exposes one switch per package target. \`.github/workflows/astrail-docker-publish.yml\` exposes a separate \`publish_image\` switch for container publishing. Verification always runs first. A publish job only runs when its switch is set to \`true\` and \`confirm_publish\` is exactly \`publish\`, and the job fails early if the required package-manager or registry secret is missing.
## Hosted MCP Source Of Truth
Generated packages call:
\`\`\`text
${server.hosted_endpoint ?? `/api/mcp/${server.id}`}
\`\`\`
Keep upstream API tokens out of generated code. Use \`ASTRAIL_API_KEY\`, provider credentials stored in Astrail, or your own secret manager.
`;
}
function buildMaintenanceGuide(server: McpServer) {
return `# Maintenance Guide
This bundle is designed to be regenerated by PR whenever the source contract changes.
## Update Loop
1. Astrail discovers or receives the latest OpenAPI/docs source.
2. Astrail regenerates endpoint maps, SDK clients, docs, and MCP manifest files.
3. \`.github/workflows/astrail-regenerate.yml\` opens a PR in this repo.
4. Review diffs in generated clients, \`docs/REFERENCE.md\`, \`openapi/endpoint-catalog.json\`, and \`mcp/manifest.json\`.
5. Merge and publish with your normal release policy.
## Breakage Review
Look for:
- Removed endpoint keys or SDK methods.
- Auth changes from public to required.
- Destructive operations becoming newly exposed.
- Response shape or pagination changes.
- New scopes that security should approve.
## Runtime Proof
The generated clients intentionally call the hosted Astrail MCP endpoint for ${server.name}. Logs, trace IDs, auth-required states, upstream status, and rate-limit behavior remain centralized in Astrail.

Generated by Astrail SDK Factory.
## Start here
You do not need to publish a package or understand MCP first.
1. Open \`START_HERE.md\` for the two-minute setup.
2. If you use Codex, Claude, Cursor, or another coding agent, paste \`VIBE_CODER_PROMPT.md\` into it.
3. Or run \`npm run quickstart\` from this folder.
This bundle gives you:
- \`astrail.yaml\` config inferred from the server endpoint map
- TypeScript SDK
- Python SDK
- Go SDK
- Java SDK
- Kotlin SDK
- Ruby SDK
- C# SDK
- PHP SDK
- MCP npm bridge package
- Terraform integration scaffold
- CLI scaffold
- Docker runtime proxy scaffold
- smoke tests
- GitHub Actions regeneration template
- MCP endpoint docs and machine-readable manifest
- endpoint reference docs and endpoint catalog JSON
- publishing and maintenance runbooks
- runnable TypeScript/Python examples
- custom method hooks
## TypeScript
\`\`\`bash
cd typescript
npm install
npm test
\`\`\`
\`\`\`ts
import Client from "./dist/index.js";
const client = new Client({
endpoint: process.env.ASTRAIL_MCP_ENDPOINT!,
apiKey: process.env.ASTRAIL_API_KEY,
});
${tsExample}
\`\`\`
## Python
\`\`\`bash
cd python
python -m py_compile ${pythonPackage}/client.py
\`\`\`
\`\`\`python
import os
from ${pythonPackage} import Client
client = Client(
endpoint=os.environ.get("ASTRAIL_MCP_ENDPOINT", "${endpoint}"),
api_key=os.environ.get("ASTRAIL_API_KEY"),
)
${pyExample}
\`\`\`
## More Targets
Generated clients for Go, Java, Kotlin, Ruby, C#, and PHP call the same hosted MCP JSON-RPC endpoint and expose endpoint-specific helpers plus generic \`callEndpoint\`, \`callTool\`, \`searchDocs\`, and \`execute\` methods. Terraform output is an infra scaffold for wiring the hosted endpoint and API key into agent runtimes.
The generated MCP bridge in \`mcp-package\` exposes an npm package with a stdio server binary for Cursor, Claude Desktop, Claude Code, and VS Code-style \`mcpServers.json\` configs. The generated CLI in \`cli/bin/astrail.mjs\` can initialize the MCP endpoint, list tools, call tools, run docs search, and execute Code Mode calls from CI or a terminal.
See \`docs/SDK_TARGETS.md\` for target-specific files, \`docs/REFERENCE.md\` for endpoint methods, \`docs/MCP.md\` and \`mcp/INSTALL.md\` for MCP client setup, \`mcp/manifest.json\` for agent metadata, \`docs/MCPB_AND_DEEPLINKS.md\` for installer placeholders, and \`custom/custom-methods.yaml\` for custom method hooks that survive regeneration.
## Automate updates
This repo includes \`scripts/pull-astrail-sdk.mjs\`, \`scripts/verify-generated-sdk.mjs\`, \`.github/workflows/astrail-regenerate.yml\`, \`.github/workflows/astrail-publish.yml\`, and \`.github/workflows/astrail-docker-publish.yml\`.
Set these GitHub secrets:
- \`ASTRAIL_SDK_BUNDLE_URL\` or \`ASTRAIL_APP_URL\` + \`ASTRAIL_SERVER_ID\`
- \`ASTRAIL_MCP_ENDPOINT\`
- \`ASTRAIL_API_KEY\` for private endpoints
The workflow pulls the latest generated files from Astrail, runs the TypeScript smoke test against your hosted MCP endpoint, compiles the Python SDK, verifies the SDK/docs/manifest file set, and opens a review PR.
## Publish
Publishing is intentionally opt-in. Review generated code, set package names in \`astrail.yaml\`, then connect npm, PyPI, Maven, RubyGems, NuGet, Packagist, registry, Docker, or release credentials in CI. Use \`docs/PUBLISHING.md\`, \`.github/workflows/astrail-publish.yml\`, and \`.github/workflows/astrail-docker-publish.yml\` as release starting points.

1. Open a terminal in this folder.

The quickstart verifies the download, installs the TypeScript SDK, builds it, connects to:

## Using a coding agent?
Open \`VIBE_CODER_PROMPT.md\`, copy everything in it, and paste it into Codex, Claude, Cursor, or your preferred coding agent. The prompt tells the agent how to integrate this SDK without exposing your API key.
## What success looks like
The final terminal line is:

After that, open \`examples/typescript.mjs\` or \`examples/python.py\` and copy the example into your app.
