How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 31 of 102 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 39 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability71
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 404 tokens (~101/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage92
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 77% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "robyn_cross_chain" implies "execute" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
robyn_cross_chain Move value cross-chain, gasless ~164
Execute a gasless cross-chain move: the server signs ONE Permit2 intent and Robyn fronts all native gas on both chains + the bridge, reimbursed from the token. The agent pays no gas and signs nothing else. Requires ROBYN_SIGNER_KEY in the server env, and a one-time Permit2 approval of the token. Returns a route id — track it with robyn_route_status.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string | yes | amount in fromToken base units |
| fromChain | number|string | yes | – |
| fromToken | string | yes | token address on the source chain |
| toAddress | string | – | recipient (defaults to the signer) |
| toChain | number|string | yes | – |
| toToken | string | yes | token address / symbol on the destination |
No output schema declared.
No examples provided.
robyn_mesh Robyn mesh ~43
List the Robyn gasless chains and the cross-chain route graph (22 EVM nodes + Stellar), plus the relayer/Permit2 addresses. No credentials needed.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
robyn_quote Quote a gasless cross-chain route ~158
Best gasless route to move a token from one Robyn chain to another. Returns estimated output, the bridge used, duration, and the Robyn fee. Read-only — moves nothing.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string | yes | amount in fromToken base units (e.g. "25000000" = 25 USDC) |
| fromChain | number|string | yes | source chain id, or "stellar" |
| fromToken | string | yes | token address on the source chain (0x0000…0000 for native) |
| toAddress | string | – | recipient on the destination chain |
| toChain | number|string | yes | destination chain id, or "stellar" |
| toToken | string | yes | token address / symbol on the destination |
No output schema declared.
No examples provided.
robyn_route_status Track a cross-chain route ~39
Status of an in-flight route by id (BRIDGING → DONE), with the destination tx once delivered.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | – |
No output schema declared.
