## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 6 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool definitions to assess.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool text to scan.
- **Capabilities**: 0/100
  - Protocol version not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we never saw its MCP handshake.

**Unverified: 6 categories.** Categories scored 0 because we could not verify them: 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.

## Install

### How do I install the esa MCP server?

esa runs locally as a container image, launched with docker run --rm -i -e ESA_ACCESS_TOKEN ghcr.io/esaio/esa-mcp-server:0.15.2. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

## Common questions

### What is the esa MCP server?

esa is an MCP server listed in the public MCP registry as io.github.esaio/esa. Official MCP server for esa.io - a documentation sharing service for teams. This page covers its container image (ghcr.io/esaio/esa-mcp-server).

### Is the esa MCP server safe to use?

esa scores 6 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.

### Is the esa MCP server still maintained?

esa is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the esa MCP server?

VerifyMCP ran 5 checks on esa, covering Source repository, Provenance, License, Maintenance and 1 more. 9 items could not be completed, a gap on our side rather than a finding about esa: Malware scan, Known CVEs, Install scripts, Dependency health and 5 more. 6 categories score 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a container image, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
