Chroma’s official MCP server: vector search and collection management for RAG workflows.
MySQL Legacy is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Inspect and query MySQL 5.0–5.6; opt-in INSERT/UPDATE/DELETE/DDL. Live-verified 5.0–8.0.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --env 'MYSQL_LEGACY_HOST=${MYSQL_LEGACY_HOST}' --env 'MYSQL_LEGACY_USER=${MYSQL_LEGACY_USER}' --env 'MYSQL_LEGACY_PASSWORD=${MYSQL_LEGACY_PASSWORD}' --transport stdio mysql-legacy-mcp '--' npx -y mysql-legacy-mcp
# 2 — ask your agent for something these tools do
# mysql_legacy_ping, mysql_legacy_select, mysql_legacy_insert and 8 more
It needs MYSQL_LEGACY_HOST, MYSQL_LEGACY_USER, MYSQL_LEGACY_PASSWORD: this reads them from your environment, so export them first.
MySQL Legacy costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts MySQL Legacy as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. Claude Code reads MYSQL_LEGACY_HOST (Database host or local tunnel endpoint), MYSQL_LEGACY_USER (Dedicated database reader account), MYSQL_LEGACY_PASSWORD (Nonempty database account password) from your environment each time it starts the server, so the value stays out of its config: export them in your shell profile (macOS, Linux), or run setx MYSQL_LEGACY_HOST …, setx MYSQL_LEGACY_USER …, setx MYSQL_LEGACY_PASSWORD … and open a new terminal (Windows). The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user --env 'MYSQL_LEGACY_HOST=${MYSQL_LEGACY_HOST}' --env 'MYSQL_LEGACY_USER=${MYSQL_LEGACY_USER}' --env 'MYSQL_LEGACY_PASSWORD=${MYSQL_LEGACY_PASSWORD}' --transport stdio mysql-legacy-mcp '--' npx -y mysql-legacy-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
It reaches a system of yours, so it needs your own credential rather than the publisher’s: MYSQL_LEGACY_HOST — Database host or local tunnel endpoint; MYSQL_LEGACY_USER — Dedicated database reader account; MYSQL_LEGACY_PASSWORD — Nonempty database account password. You set them in your own client’s config, on your machine — this marketplace never holds it.
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
11 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Checks the MySQL connection with SELECT VERSION() AS version and returns {connected, version}. Call this first after connecting. For schema use mysql_legacy_list_tables; for row data use mysql_legacy_select.
No parameter schema on file.
Runs exactly one SELECT supplied in sql. Rejects SELECT INTO and locking reads; truncates by MYSQL_LEGACY_MAX_ROWS and MYSQL_LEGACY_MAX_RESULT_BYTES. On MySQL 5.6.5+ wraps in START TRANSACTION READ ONLY unless MYSQL_LEGACY_DISABLE_READ_ONLY_TRANSACTIONS=true. For columns use…
No parameter schema on file.
Runs exactly one INSERT supplied in sql. Off unless MYSQL_LEGACY_ALLOW_INSERT=true. Returns insertId and affectedRows. INSERT ... ON DUPLICATE KEY UPDATE is accepted and can overwrite existing rows. For UPDATE/DELETE/DDL use mysql_legacy_update, mysql_legacy_delete, or mysql_legacy_ddl.
No parameter schema on file.
Runs exactly one UPDATE supplied in sql. WHERE is required and cannot be disabled. Off unless MYSQL_LEGACY_ALLOW_UPDATE=true. Returns affectedRows and changedRows. To empty a table use TRUNCATE via mysql_legacy_ddl, not a WHERE-less UPDATE.
No parameter schema on file.
Runs exactly one DELETE supplied in sql. WHERE is required and cannot be disabled. Off unless MYSQL_LEGACY_ALLOW_DELETE=true. Returns affectedRows. To empty a table use TRUNCATE via mysql_legacy_ddl, not a WHERE-less DELETE.
No parameter schema on file.
Runs exactly one table-level CREATE, ALTER, DROP, TRUNCATE, or RENAME supplied in sql. Off unless MYSQL_LEGACY_ALLOW_DDL=true. DROP and TRUNCATE are irreversible. Rejects DROP DATABASE, views, and indexes. For row changes use mysql_legacy_insert, mysql_legacy_update, or mysql_legacy_delete.
No parameter schema on file.
Lists database names via SHOW DATABASES. Hides mysql and information_schema unless include_system_databases=true (or MYSQL_LEGACY_HIDE_SYSTEM_DATABASES=false). Then pass a name to mysql_legacy_list_tables. Does not list tables or columns.
No parameter schema on file.
Lists base tables and views in one database via SHOW FULL TABLES FROM database. Pass database. For column types use mysql_legacy_describe_table; for CREATE TABLE text use mysql_legacy_show_create_table; for keys use mysql_legacy_list_indexes. To list databases first, use mysql_legacy_list_databases.
No parameter schema on file.
Lists columns for database.table via SHOW FULL COLUMNS, including type, nullability, keys, comments, and collation. Use this for per-column metadata. For the full CREATE TABLE text and default charset use mysql_legacy_show_create_table. For index column order use mysql_legacy_list_indexes.
No parameter schema on file.
Returns SHOW CREATE TABLE for database.table plus the parsed default charset. Use this for DDL text. For per-column types and collation use mysql_legacy_describe_table. For unique/non-unique keys use mysql_legacy_list_indexes.
No parameter schema on file.
Lists indexes for database.table via SHOW INDEX (key name, columns, uniqueness, type). Use this for keys. For column types use mysql_legacy_describe_table; for full DDL use mysql_legacy_show_create_table.
No parameter schema on file.
- Every tool, no call limit
- No card, and mcprush charges nothing for it
- Source published under MIT
- Runs on your machine — nothing of it reaches our gateway
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install MySQL Legacy or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | high | capability blast radius (high) — client exposure if the model is manipulated | −6 |
| verification-discount | source | publisher verification (provenance) — cryptographic build provenance ties the artifact to its source | −0 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tools were statically extracted from the published source (11 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. high is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| mysql_legacy_ping | untrusted-input | untrusted-input: declares openWorldHint: true (interacts with entities outside the server) |
| mysql_legacy_select | sensitive-sourceuntrusted-input | sensitive-source: parameter "sql"; untrusted-input: declares openWorldHint: true (interacts with entities outside the server) |

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.2.1. Pin a release below and the command asks for exactly that one.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish MySQL Legacy can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
