Firecrawl search and scrape tools examples/with-firecrawl-search/.env.example, examples/with-firecrawl-search/src/tools.ts, examples/with-firecrawl-search/README.md |
Adds authenticated Firecrawl v2 search and scrape tools with structured results and errors. Search supports optional Markdown. The tools truncate returned content at documented limits. The README documents tool parameters and content limits. |
Agent setup and example integration examples/with-firecrawl-search/src/index.ts, examples/with-firecrawl-search/package.json, examples/with-firecrawl-search/tsconfig.json, examples/with-firecrawl-search/README.md, examples/README.md |
Adds a LibSQL-backed research agent that uses the tools, along with package and TypeScript configuration. Documents installation, environment setup, usage, and troubleshooting. Adds the example to the examples list. |

Merge Risk: 
8d769
-
The example is mergeable; documented setup and integration paths are supported.
Security architecture risk: 
c1820
-
The example exposes paid search and scraping capabilities without configuring request authentication, while the server listens on all interfaces by default. Callers who can reach it can consume the configured account’s resources. Private network restrictions could reduce exposure, but those restrictions are not established here.
Retained concerns
- Medium · security · inferred: The new example attaches process-owned Firecrawl authority to a server with no configured request authentication and an all-interface bind default. A caller able to reach the listener can submit research requests that invoke the tools using the configured account, creating unauthorized resource-consumption exposure. These server defaults predate the PR, but this example introduces the Firecrawl capability behind them; deployment-level containment is unknown.
Security review details
-
Security Blast Radius
- inferred — The supported resource-abuse scope is the reachable example process and its configured Firecrawl account, including available credits and service capacity. The bearer credential is sent to the fixed provider endpoint, while the requested scrape URL is a body field. Consequently, host-network SSRF or credential delivery to the scraped site is not established by this flow; provider-side destination controls remain unknown.
Security Findings and Attack Paths
- inferred — A network caller who can reach the default listener can submit an unauthenticated research request, cause registered tools to execute, and consume the environment’s provider authority. Repeated requests are not bounded by the tool’s per-call result limit or timeout. This exposure arises from adding the new capability behind existing server defaults, not from changing those defaults.
Trust Boundaries and Controls
- observed — Caller-to-server authentication is not configured, while server-to-Firecrawl authentication uses an environment bearer key. A missing key prevents provider calls. The scrape URL receives string-type validation only, and provider content enters the research workflow without an enforced search-result provenance requirement. This is a boundary description, not proof of provider-side SSRF or a successful content-driven attack.
Resilience and Maintainability Implications
- observed — The tools have no local reservation or multi-step mutation to roll back, and failures terminate locally with structured results. Their fetch signal uses only the local timeout rather than the caller’s cancellation context. Remote completion, cancellation, and charging after an aborted fetch are unverified; repetition can issue another independent provider request. Shared-memory concurrency and recovery guarantees are also unresolved, not established vulnerabilities.
Hardening Proposals
- proposed — Make the example explicitly local-only through a loopback bind, or configure request authentication before wider exposure. For shared deployments, enforce caller-specific usage and concurrency budgets, establish authenticated conversation ownership, and propagate cancellation into provider requests without assuming that client abort refunds or terminates remote work.

Review comments at @examples/with-firecrawl-search/src/index.ts:
- Line 5: Update the local import of firecrawlScrapeTool and firecrawlSearchTool
to use the explicit .js extension so the emitted ES module resolves under native
Node ESM.
Review comments at @examples/with-firecrawl-search/src/tools.ts:
- Line 29: Update the JSON parsing fallback for response.json() so parse errors
are rethrown when response.ok is true, allowing both tools to return their
structured error results. Keep the empty-object fallback for unsuccessful
responses so existing HTTP status error handling is preserved.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick winBuild the workspace packages before starting the example.
The README runs
pnpm devimmediately afterpnpm install. The example imports workspace packages whose ESM exports target generateddistfiles. Installation does not build those packages, sotsx watch --env-file=.env ./srccan fail with a missing-module error.Suggested fix
pnpm install ``` + Build the linked VoltAgent packages: + + ```bash + pnpm --filter '@voltagent/*' build + ``` + 2. **Configure environment variables**:<repository_evidence>
The documented sequence runspnpm installand thenpnpm dev.
The example'sdevscript istsx watch --env-file=.env ./src, and its source imports@voltagent/core,@voltagent/internal,@voltagent/libsql,@voltagent/logger, and@voltagent/server-hono.
The imported workspace packages map ESM imports to generateddistfiles such as./dist/index.mjsand./dist/main/index.mjs.
The root manifest definesbuildseparately aslerna run buildand definesprepareonly ashusky install.
The linked packages definebuildanddevscripts but noprepare,install, orpostinstallbuild hook.
The reviewed checkout contains no trackeddistentries for the inspected linked packages.
The lockfile links the example dependencies to the local workspace package directories.
tsxcan transpile imported TypeScript dependencies, but package exports still select the dependency's declared entry point.
In a clean checkout, the workspace links resolve these imports through theirdistexport targets, and the documented install sequence does not create those files. The example can therefore fail before startup.

Hey, I'm Juampi from the Firecrawl team. Thanks for VoltAgent and for keeping the examples folder open to integrations. This PR adds a small Firecrawl example.

What is the current behavior?
There is no Firecrawl example in
examples/.What is the new behavior?
examples/with-firecrawl-searchis a research agent with two tools:firecrawlSearchsearches the web and returns titles, URLs and descriptions. It can also return each result's page as Markdown in the same call (scrapeContent: true).firecrawlScrapefetches any URL as clean Markdown.The agent searches first, reads the one or two most relevant pages when the descriptions are not enough, and cites the URLs it used. It follows the layout of the other web search example, uses
fetchagainst the Firecrawl v2 API (no new dependencies), and adds one line toexamples/README.mdplus the lockfile importer entry for the new package.Notes for reviewers
How I tested it, with
gpt-4o-miniagainst the published@voltagent/*packages, callingPOST /agents/Web%20Research%20Agent/text:firecrawlSearch, thenfirecrawlScrapeon two of the results, and answered with Node.js 24 and 22 and their end-of-life dates, citing both pages.firecrawlSearchonly and answered with three cited links.I also called both tools directly with
scrapeContent: true, a missing key, an invalid key (401) and an invalid URL (400). Each error returns a{ success: false, error, message }result instead of throwing.tsc(the example'sbuildscript),biome check examples/with-firecrawl-searchand Prettier on both READMEs pass. No changeset, since examples are not published.If a recipe page on voltagent.dev would help, I'm happy to write one.
