Available components
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 Security0
- Malware scan not yet available for this package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
Provenance & Transparency32
- 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
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 99 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 477 tokens (~59/item across 8 items; 8 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management83
- Stability observed for 25 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 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
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
How do I install the Emercoin Agent MCP server?
Emercoin Agent runs locally as a container image, launched with docker run --rm -i docker.io/emercoin/mcp:0.1.0. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

Background: How many MCP packages publish verified provenance →
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 →
login ~64
Begin GitHub login (device flow). Returns a short code; SHOW IT TO THE USER and ask them to open `verification_uri` and enter `user_code`, then call `login_poll(session_id)` to finish. No GitHub token needed from the user.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
login_poll ~89
Finish device-flow login once the user has authorized. Polls for up to `wait_seconds`, caching the session JWT on success. Returns {status: "authorized", github_id, github_login} or {status: "pending"} — if pending, the user hasn't authorized yet; call this again.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | – |
| wait_seconds | integer | – | – |
No output schema declared.
No examples provided.
login_with_token ~53
Dev/CI fallback: log in with a pre-issued GitHub token (works only if the gateway has raw-token login enabled). Prefer `login()` (device flow).
| Name | Type | Req | Description |
|---|---|---|---|
| github_token | string | yes | – |
No output schema declared.
No examples provided.
node_status ~23
Get Emercoin node sync status (blocks, headers, progress, synced).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
read_record ~45
Read any NVS record by name (e.g. ai:gh:12345 or ai:gh:12345:mem:<hash>).
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | – |
No output schema declared.
No examples provided.
register_identity ~58
Register/refresh this agent's on-chain identity record (ai:gh:<github_id>). `address` is the agent's Emercoin address, later used for signature login.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | – |
| metadata | – | – | – |
No output schema declared.
No examples provided.
store_memory ~65
Store a research/memory hash on-chain (ai:gh:<github_id>:mem:<hash>). Keep the body off-chain (e.g. IPFS); only its hash + metadata go on-chain.
| Name | Type | Req | Description |
|---|---|---|---|
| content_hash | string | yes | – |
| metadata | – | – | – |
No output schema declared.
No examples provided.
store_memory_batch ~80
Store many memory hashes in ONE atomic on-chain transaction (cheaper and atomic vs. calling store_memory repeatedly). Each record is {"content_hash": str, "metadata"?: dict}. Returns one txid for the whole batch. Counts as len(records) against the per-minute write tier.
| Name | Type | Req | Description |
|---|---|---|---|
| records | array | yes | – |
No output schema declared.
No examples provided.
What is the Emercoin Agent MCP server?
Emercoin Agent is an MCP server listed in the public MCP registry as io.github.emercoin/emercoin-agent. On-chain identity and durable memory for AI agents on the Emercoin blockchain (NVS). This page covers its container image (docker.io/emercoin/mcp:0.1.0).
Is the Emercoin Agent MCP server safe to use?
Emercoin Agent scores 46 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Emercoin Agent MCP server expose?
Emercoin Agent exposes 8 tools: node_status, login, login_poll, login_with_token, register_identity, and 3 more. Their descriptions and schemas cost roughly 477 tokens of context every time the server is loaded.
Is the Emercoin Agent MCP server still maintained?
Emercoin Agent is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
